I've a few questions for you guys about a rifle I'm cobbling together.

1) What are you 243 A.I. guys using for dies? I'm looking at the 2 die Redding set (neck sizer and seater). Will I want to have a body die, or will touching the shoulders be completely unnecessary?

2) For those of you that have had 700 barrels punched out, are you having them set back to kiss lands from the mag? Looking at some 243 Win dummies with 105 A-Maxes, it seems that a 2.8" COAL leaves the base of the bullet right at the Neck/Shoulder junction.
Redding FL dies and LCD. The FL die is for bumping the shoulder every few loadings, which does need to happen, LCD for neck-sizing, and the Redding seater works for me when it comes to bullet seating.

Yes, set back a thread, punch AI to kiss the 105AM at mag-length. An OAL of 2.813" kisses the AM for me, and the junction of the boat tail and the bearing surface sits right around (just a hair under) the neck-shoulder junction of the brass. An OAL of 2.820" might be perfect for lining up those two reference points.

If on the cheap, a take-off 700 barrel in .243 can be worked to a pretty decent outcome. If screwing on a premium tube anyway, I'd skip the crap and go right to a .260 if you plan on using the rifle a lot on game larger than deer. Not that the .243 can't handle it, just that the 140AM type bullets might be a bit better choice for the task of elk/moose/bear.

Both of these pics are at 2.813"

Jord, someone graciously offered me an SS 24" 700 tube that's already been punched out A.I.

I'll have my smith check where it's at in accordance to lands/mag restraints when he puts the sucker on there, and if it doesn't jive I'll ask if he can set it to a kiss at 2.815", so my loaded rounds sit around 2.810".

You're using IMR 4350, correct? I was thinking 78282ssc as a first thought, but if 4350 will do it...
Posted By: Tanner Re: Sporter 243 A.I. Revisited - 01/18/13
BTW... those loaded rounds are absolutely dead sexy.
Sweet! That's a nice fella, whoever it is!

Why load your ammo 0.005" shy of a kiss? Unless it shot better that way, of course, but there's no reason not to start at the start...

Yup, 43.5gr of IMR4350 for around 3113fps on the chronograph, but my drops match the data for 3157fps. I have lots of 7828ssc, but I also have about 8lbs of IMR4350, with nothing but the .243AI to use it in. So far, I can't really ask for more than IMR4350 gives me, except for maybe 100fps more velocity wink Absolutely great accuracy, pretty good velocity, and I haven't noticed any real temperature sensitivity in this application. Once that IMR4350 gets burned through, I'll likely try H4350 or even H4831sc. I'm sure 7828ssc would work wonderfully, as well.
Posted By: Tanner Re: Sporter 243 A.I. Revisited - 01/18/13
Just in the last couple months I've found my A-Maxes like jumping .005", but the 105s could be totally different. You can bet I'll start at the start and kiss 'em... grin

I only lean 7828ssc because of my obsession with consolidation, and getting down to 3 powders for all of my reloading would be spectacular laugh ... although I use 4350 in the 25/06, as well.
This is going to be THE year of the .243 AI...
It's like the plague.

Tanner,

As long as the tube headspaces properly, I wouldn't worry about mag constraints on a factory tube. If it's too long, it'll have to be set back, and the new reamer run in again, and/or use a throating reamer. Also, many rounds down the barrel at this point is tough on reamers. Just throwing money down a [bleep] hole. Plus, you want it under 2.800" so you can chase the lands.

Burn it up, and you'll have brass for the new tube.

But then at the rate you've been moving, it'll be down the road and you'll be on to the next adventure before you know it.....


grin





Posted By: Tanner Re: Sporter 243 A.I. Revisited - 01/19/13
Thanks aalf. It sounds like there's around 200 rounds on this barrel, which doesn't seem to be too bad, but I'm sure you're right on the reamer thing... I'll see what the Dr. says.

Hey, as long as I keep the action it doesn't count as tripping it laugh

And I won't say you told me so on that 6.5 Lapua.... grin

You should be able to massage about 0.020" of headroom in the mag box to chase lands if you throat to kiss the 105AM at 2.815". Go to AICS mags, and you won't even have to concern yourself with mag length- just throat to seat the bullet's BT/bearing surface junction at the base of the neck...
Posted By: Tanner Re: Sporter 243 A.I. Revisited - 01/19/13
Spill your guts!

I just bought 800 105 A-Maxes for 18/100 so they better 'effin' shoot.
WHY CAN'T I FIND A DEAL LIKE THAT?!!!

I hate you.

I pay about 50% more than that, when/if I can ever find any!

Would a Wyatt's be a pretty easy install and function well with a BDL Bottom metal?

I run one on my 260...works just fine, and it'll go to 2.995", give or take...
Based on the comments of several very trusted individuals, including a couple of well-respected guys from the 'fire, Wyatt's doesn't seem to have the same quality and fitment as the AICS BM's, such as the Atlas...*hint*

My AICS mags are 2.920" with the re-enforcing plate installed (more of a concern for military applications), and 2.995" with it removed.

I agree with that assessment... the Wyatts feels like a lighter metal is used over the factory mag box. I did have to tweak it a bit to keep the rounds in the box IIRC, but regardless, it wasn't a big deal.

Weight and cost over the other BM's was the deciding factory for me on that build.
Posted By: Tanner Re: Sporter 243 A.I. Revisited - 01/19/13
I'll probably run the factory mag box until I upgrade barrels, and then get fancy from there.

A tumbler, Lyman moly, and 800 105s sit atop my bench... McM Mountain Rifle w/ BDL bottom bondo finish sans recoil pad is inbound, along with an SS 24" 700 takeoff already punched 243 A.I.... I'm told this tube kissed 105s at 2.762" on the previous action, so I'm interested to see where it's at once headspaced onto my own. If I can control it whatsoever, I'll have the Dr. set it to kiss at 2.8", in order to use up allllll that good powder column.

I will likely clear coat the stock, and run it as long as I can stand the Ugly Duckling Bondo look, glue on a pink flip flop pad, and bed/float the sucker. Talley LWs with a 3-9x40 M1 ele in the saddle will do the lookin'.

Anybody got's a weight guess? By my best estimation, it should be a skosh over 7.5# with 3 in the gut.

For anybody that GAF...

Tanner, what contour is the takeoff? Sounds like its going to be a great project. Have you Molly's before or is this your first go?

I would think your smith can throat that to whatever the hell you want. Those 105 Amax kick ass.
Posted By: Tanner Re: Sporter 243 A.I. Revisited - 01/26/13
Sporter tube, and this'll be my first venture with moly. Hopefully it works out nicely.

The only reason I question being able to throat where I want is because like aalf pointed out, the barrel has had some rounds down it and might be tough on a reamer. I doubt that'll present an issue, though...
I wouldn't overthink the throating issue, it will fit it your magazine and shoot basically the same velocity regardless.

Might try moly coating only a hundred or so bullets first, to see if you like it. It's not too hard to remove, but still....
I quit using moly years ago, and wish I would've stopped earlier, as sacreligious as that sounds tired.
Posted By: Tanner Re: Sporter 243 A.I. Revisited - 01/26/13
Why'd ya quit using it?
It seemed like the advantages were mostly in my mind, while the disadvantages (dirty to apply and deal with, cleaning cycles weren't much different) were enough that it just wasn't worth it. Mostly I just got lazy, quit applying it and didn't notice any difference, so I left it behind.

Then I tried UBC, which seemed to work better as far as helping out with less cleaning, and was a one time deal. No more moly for me!
Posted By: Tanner Re: Sporter 243 A.I. Revisited - 01/26/13
Gotcha'. I didn't plan on chuckin' all 800 in the tumbler at the same time, so I'll definitely see how the first 100 or so work and shoot.

If I can find enough powder to shoot some bullets, I will be a happy camper.
I'm with PG, as for me and my barrels they won't see moly...grin

Short story, while back my 700/Mash took ill. I took it to my smith, he scoped it and proceeded to cuff me. Told me to look at the moly build up. He said if you can get rid of it it'll go back to shooting. Took some time but I got rid of it and low and behold the Mash went back to playing nice.

Now my 223 Ack didn't handle it that way so maybe all don't. But one very good tube did so that sealed it for this old perro.

Dober
Posted By: Tanner Re: Sporter 243 A.I. Revisited - 01/26/13
I'm going to at least give the stuff a shot and see how the barrel reacts to it. If it doesn't jive, I'll scrub the sucker out and start naked,
Posted By: rflshtr Re: Sporter 243 A.I. Revisited - 01/26/13
Mine is a rem 700 short action with a new take off sporter
Rem 700 barrel like yours set back and reamed to seat bullets at 2.80" initially. I have been fireforming and tried a few newly formed brass with 105's and RE 15 with great results. No moly yet for me. Redding 3 die set and this is my second .243 AI. Still working up loads but just under 3000 fps now. Anybody using Retumbo powder for this one? Target is around 3100 fps depending on best accuracy. Check out the 6mm BR website if you have not already done so.
If all you want is 3100fps, then I'd suggest you load up 43.5gr IMR4350, and I bet your groups will be impressive. Speed should be right close to 3100.

I would forget about moly and just Dyna-Bore Coat.

+1. The 2.762" will not take any noticeable volume over a 2.8" on powder capacity and the 2.762" will allow you to chase the lands a little more.

John
Posted By: Tanner Re: Sporter 243 A.I. Revisited - 01/26/13
Thanks for the thoughts. I'll be interested to see how close it headspaces out and what adjustments are needed... Leaving it short of 2.8" is probably a good idea I suppose.
aalf,

Yes, moly can build up. Kevin Thomas proved that years ago with extensive tests at the Sierra lab.

He found out it built up in the throat area over about a 50-round cycle to the point where accuracy suffered, then the excess blew out and accuracy came back--sometimes.

I often saw the same thing when I was fooling with moly a decade or so ago, which is why I also much prefer DBC .

I was hitting 3000 today in a standard 243 with a 22" barrel. Didn't see any signs of pressure, but I was a little surprised with the velocity. My first go round with the 105...
SAS-how much and of what were you driving?

Thx
Dober
41.5 of RL17. No pressure signs, but velocity was a little higher than expected.

[Linked Image]

[Linked Image]

I stopped there when I saw the velocity. I've loaded a few at 42 to try in the morning. Plan on running them over the chrony and will examine the brass.
I will add that I ran 3 through the screens at that charge and 3017 was the fastest. I also saw 2991 and 3003. I'm gonna play around more tomorrow.
Thx, I must of missed it but what'd you get for a .243? Also would be interesting to see how long the primer pockets stay reasonably tight.

I believe that the Aliant site calls for 40.8 with a 100 grainer. So far my experience with R17 has been that with every cartridge I've tried it with the load on the site was Max in my guns. Some of my loader friends concur as well.

Keep me in the loop as to how many loadings you can get thru and keep the pockey's tight.

Thx
Dober
Mark,

I try to always keep a 243 on hand. You might laugh, but I was shooting a Ruger American Rifle. I had one in 243 when they first hit the shelves, sold it and bought another a few months later. Both have been tack drivers.

I wanted a 9 twist 243 to try this bullet and this was all I could find locally.

I started at 39grs and worked up. I have some loaded at 41 I'm going to try too. I'm guessing 41.5 is on the warm side. That's Hornadys max for that bullet, but velocity is in the 2900's out of a 24" barrel.
Does the newest Horn manual carry R17 data?

And the .243's long been a fav of mine as well. One heck of a good round!

Dober
My 8th edition has lots of RL17 data. Primer pocket life interests me too! Actually, I'd be happy with an accurate load at 2900.
I've not done much with a .243 for some time but from the old school powders like 4350 and 4831's I'd be very happy with 2900 out of a 22" with a 105.

Dober
Posted By: rflshtr Re: Sporter 243 A.I. Revisited - 01/27/13
In the sporter barrel, I will take whatever I can get over 3100 but not at the expense of accurracy, barrel life and case life. I have another one with a varmint barrel that I push harder and the throat is eroding after only about 1000 rounds. On the fourth loading of the cases and primer pockets still ok in that one. I will try the IMR 4350 load you suggest and see.
Posted By: rflshtr Re: Sporter 243 A.I. Revisited - 01/27/13
Dober, the 9th Hornady manual shows RL-17 for the .243 Win with 24" barrel in their rifle and powder charges range from 35.9 to 41.5 and velocity with the 105 grain A-max ranges between 2500 at the low end to 2900 at the high end.
Posted By: Tanner Re: Sporter 243 A.I. Revisited - 01/27/13
SAS, how was the accuracy with your first couple loads?

Retumbo spat out 3030fps from a 24" tubed SAAMI 243 for me... looks like '17 is kicking butt.
Not bad. First group was low and off the paper (but on the target backer). It was probably 1.5ish. I mounted a new scope and had shot it at 25 with another load. The second group was better, close to an inch. I'm going to shoot a little more this afternoon. I'll have a better idea then.

Yesterday's group after adjustments.....

I plan to shoot at 200 today. Maybe that will tell me more. Hopefully by next weekend I'll be ready to start walking it out a little.

This stuff cracks me the [bleep] up!

I've shot/shoot moly in over 100 of my own barrels and have yet to see a downside...but I'm of course all ears and look forward to naysayers.(grin) Pards are good for a few hundred more spouts,if only as a gross understatement and I'm thinkin' all case capacities and bore sizes,are more than comfortably covered in the extrapolation.

I know,I know...it's hygroscopic too and the bane of a "moist" climate. I love all of that schit,which is why I reside in the Desert at a lofty elevation as a safety net! Laffin'!

Now as to a SAAMI 243Win and twist rates,both Rem and Ruger will easily stabilize 105's and are routinely throated nicely in conjunction with their magboxes,so as to allow a VLD 'Max kiss. Them is good things.(hint)

'17 is a very nice way to fly in the SAAMI hull with 105's,but I jump to '22 in the AI version with same.

(addendum for 'smoker)

42grs of '17 in R/P hulls lit with 200's and a moly 105'Max kiss,makes right at 3K fps in a SAAMI chamber/OEM spout...though a guy could certainly lean harder on 'em. ES/SD is in the 10fps realm,with .003" neck tension.


(Re-addendum for works)

Now saltwater and hard use in a wet climate,will affect CM parts/pieces and that's for certain...why is why I [bleep] HATE same. The Rocktucky had an OEM CM follower spring puke the other day,though it's bore hasn't seen so much as a mop in 1500rds + of 75A-Max. I've broken springs before,but never into 3pcs,which is currently my "record".(grin)

I remain a fan of shooting bores dry and the use of multiple applications of tape,throughout the day,upon muzzles.

Also a fan of an opening stance that states: "My Gunsmith says...". Cracks me the [bleep] up,that folks who cain't even shoot enough to inform themselves,feel compelled to give "answers" to others. Dumb [bleep] couldn't knock the new offa used pair of boots.

Amen. I'd shoot moly rim fires if they were available. I've only one rifle left to convert to moly but the thought of scrubbing to bare steel first makes me want to donate it to Goodwill instead as I'd rather have trigger time with the others.

Still waiting to see the carnage from salt water and moly but my hunch is that I'll kill bigfoot first.
Boxer,

When shooting jacketed bullets my default dies are Redding Type S Full Size Bushing Die, RCBS Competition Seater die (I like clicks), and Redding Competition shell holders..
You control your headspace with the various sized (thickness) shell holders..
Midsouth often sells Redding and RCBS dies individually...

No need for a body die, although they or a form & trim die are handy for necking down larger caliber and or longer brass to better fit/fill your chamber on initial fire forming..

Already [bleep] up and ruined 2013,by catching the biggest [bleep] fish of the year...right outta da gate,which sorta sucks.

I don't have to worry about topping a 43" Hen this year(or any other),though I reckon I'll bump a few pickle Bucks before all the dust settles. The Old Gal was heavy and deep and 23" girth is slighting her,but I didn't find the tape in my pack,until after the fact and she swam away. So I gotta sandbag conservative with the girth,beings I didn't quantify it. 43"x23" is some SERIOUS heft. Shame I didn't catch her on the GL3 1141S I had in tow,instead of the POS Sage,as it was in the cards and I'll kick myself forever over that one.

PowerPro braid has no equal and I drive it expressly. Leader material is always Maxima Chameleon,because it too has no equal and fends abrasion like nothing else. When sumptin' new comes out,I drive it hoping for it to take the cake,but nuttin' has as of yet and I'm still waiting. I run 30# PP even on my beloved 4-8# UL 1141-S's,whether it 2500 or 3000 series Stradics. A nice combination of capacity,muscle and minimal memory. I run 30# PP on 5000 Stradics too,on a few Loomis Float rods,for fending big water after a gullywasher of a rain storm. Same goes all my Curado's and ABU Revo's,30# PP across the board. All the Pip's are stoked with 15# Chameleon typically,though I do like 18# and will slum 20# in big water or Tourney Fishing Coho for sheer volume numbers and braggin' rights with a herd of like minded azzholes trying to outnigger eachother.(grin) 20# will bank more fish before it pukes and Tourney volume is ALL about keeping a hook wet. If I can grind out a dozen fish on a single leader,before having to re-tie,I'm upping production.

I'm a grinder and never was much into [bleep] around and I tend to go for the throat,whether it Castin' or Blastin' and especially in conjunction. I've lonnnggggggggg been a believer in GOOD riggin' and lots of it,as I tend to puke alotta schit in a typical year,so spare spares interest me a bunch,as I'm tough on riggin' and cain't want a second of down time. Every day is R&D in my book and if you ain't trying sumptin' new,you can get stuck in a rut and miss the boat...and it sure as [bleep] ain't gonna be me,behind the curve.

There's method to the madness and I drive an open mind,always scouring to find a better way....while simply spending the time to ascertain what do what and more importantly WHY.

Now as to CM parts and their failures,I've had several magboxes,followers and springs,coated with various schit and have long been of the anti-coating establishment(save CL bores,which I love and Robbie's NP3). Gimme S/S and [bleep] all the CM Window Licking bullschit,because it cain't begin to hang in hard use applications,which is all that I do. Tape muzzles,shoot bores dry at the end of the day and whistle moly for MUCH longer shot strings of consistent POA/POI intersection and keep all swabs,brushes,jags and fluff outta the [bleep] bore.

[bleep] the fluff,pass the good schit and get the [bleep] outta my road...because I'm going right ahead on schit,WFO and then some. This R&R is a wrap and it's back to the Salt Mines,so it'll give others a chance to try and catch up.(grin)

I went down to 90 grain bullets in my AI as I liked the choices better in terms of a hunting bullet, and quite frankly, they shot little bitty groups (90 AB, 90 Scirocco). I'm running 44.5 of RL17 out of a 22.5 inch #1 Rock tube at 3300 fps. As Forest Gump would say, I like it uh lawt.
Posted By: Tanner Re: Sporter 243 A.I. Revisited - 01/30/13
I'm definitely going to feel inclined to shoot some 85gr TSX out of this little beauty. It'd be nice to pop an elk or two with it!

Those Scirocco's are pretty wicked looking little suckers! Too rich for my blood, though.

'48,

Talk is cheap and actions speak louder than words.(grin)

The main thing is to just shoot,as there is correlation to good practice upping one's "luck".




'traylor,

It's tough to beat the 85X/87V-Max swapaloo...if a guy is gonna stay shy of upper echelon BC's. POA/POI intersects nicely,load data shares nicely and both will perform in all things OEM,regarding twist and throating.

Never could like AccuBomb's,though I do suffer some S2's now and again. Were I unable to fling 105's,it'd be the 85/7 melding for me.

At quite a bit better than 3300.





'smoker,

The .224" 75S2 by and large,has a purty schitty profile and alotta bearing surface...though it do have a fairly rugged jacket.

L-R: 50V-Max,75HPBT Hornie.75S2,75'Max


[Linked Image]

S2 22-250AI Buck.

[Linked Image]

It's the 75A-Max for me and were I to deviate,it'd be to the 62TSX(not TTSX). 62TSX amidship,with a nekked 60V-Max to it's left and the 62TTSX to it's right,if only for conversation.

[Linked Image]

I'm done with S2's.






Tanner,

If I could save the jack to visit Alaska,I'd take sumptin' 30cal at least and prolly more likely a .338".

It'd give me a reason to buy a new rifle.
I have several 62TSX's for the 223AI. I have no 75S2's....nor have I done the mag box modification yet. That's my next project for the AI. I do have several of the 75A-Max's to play with.

Having never shot either 75 from the 223AI, I'm guessing the velocity/pressure edge goes to the A-Max because of bearing surface. What's the real world velocity difference between the two?

I know I'm not guessing that you've tried both. You chose the A-Max for a reason.....

'smoker,

The Box Mod is both a mandate and a breeze. Most of my 223AI's kiss the 75A-Max shy of 2.500" COAL,though my LTR punched out,do Linda Lovelace things greater than that dimension...but still feed/functions fine despite the smallest spacer of the fleet.

The 75 S2 will make quite a bit more pressure at a like powder charge and I tend to skin it .5gr or so. The A-Max is just oh sooooooooooooo svelte. The difference in speeds ain't huge,but you don't wanna swap 'em to/fro and like for like.

The 75A-Max rates building a rifle aropund.

I have a couple pictures for ya. Here's my Ruger American Rifle with the free bubba buddy and the Redfield Battlezone scope. $535 all up! Far from the most expensive tool in the shed, but it shoots.

Moly's easy and it sounds like you did it as I do. I've found that it doesn't take anywhere 45min. Just in case you don't want to wait that long next time. Did you degrease first? I've not found that to be super necessary, except for Nosler B-Tips.

2) For those of you that have had 700 barrels punched out, are you having them set back to kiss lands from the mag? Looking at some 243 Win dummies with 105 A-Maxes, it seems that a 2.8" COAL leaves the base of the bullet right at the Neck/Shoulder junction.


As an alternative.


I punched an ADL 243 24 inch to 6mm-284. It fed better after the follower was switched out and replaced with a WSM follower. No need for set back.

The original magazine works well with the 284 round and bullets up to 95 gr ballistic tip are not seated too deeply.


So far accuracy (with this barrel)is disappointing. Definitely lethal on deer to 300 yds, but still not moa. Unfortunately I never fired the rifle with 243 ammo so I do not know if it might have been better in its original configuration.

Federal 6.5-284 brass is easy to find and necks down easily.

A Pacific two die set with a 25 cal neck die was purchased from a 'fire member.

My rifle makes 3300 fps w/ a 95 gr bal tip & H4831 or 3500 fps w/ the 85 gr Sierra spbt and RL17.

The lube from making the bullets will eventually contaminate the moly, s/s balls, and the container that you use to moly plate with. It'll get to the point of not plating any more, just kind of a [bleep] coating that'll wipe off with little effort.

I use two plastic containers, chip dip/cottage cheese type, a couple of generous squirts of Dawn, and hot water. Play the mad scientist, pouring them back and forth in the two containers 15-20 times, eventually doing it under the faucet till the hot water runs clear. Dump them on a towel, hit 'em with a blow dryer till they're too hot to touch, and into the bowl, ready to plate.

Tan Man-

I am just starting to play with moly as well. Yours look better than mine!

I put about 350 bullets into a brand new tumbler with a lil less than 1/8 of a Tsp of moly for about an hour and a half, checking every 15 minutes or so. They look like [bleep]. Ain't coated to well and stil look copper hued.

I'm guessing the fact I didn't de-grease is the reason. New tumbler bowl prolly had some oil on it as well as the fact I had my greazy dik beaters in all the bullet boxes, as they were mostly full partials boxes I had loaded out of previously.

My plan is to wash out the bowl and bullets with some Dawn and start over.

Sweet. Those are the 2 bullets I'm most interested in, kind of funny you shoot 'em too.

Tan man,

You already know about my A-Max load, so I'll spare you the pics.

These squares are 1". Seated 0.050" off the lands, this was the first load tried with this bullet. Velocity is 3485fps from my 25.5" barrel.

[Linked Image]
Posted By: Tanner Re: Sporter 243 A.I. Revisited - 02/05/13
Phew! That sucker shoots... Funny how those X bullets love to jump like that.

That's one I might have to give a try... definitely nice insurance for closer shots on game.
Yeah, that's a 0.56MOA group. I stopped development there. I might be just a wee bit sad when this factory Rem 700 barrel pukes. Then again, I can't shed a tear when screwing on a Krieger or Bartlein grin

I plan to carry the rifle with a 5-round AICS mag full of those TTSX bullets when hiking in to a stand, and the potential for close or jump shots exists, and then swap out for a mag full of the 105AM when I expect to shoot long.
Posted By: Tanner Re: Sporter 243 A.I. Revisited - 02/05/13
It hits dead center POI wise compared to the 105 too right? Just a bit higher? That's awesome.

Blasphemy, I bet that factory 700 is cobby and has a TERRIBLE crown. I can see those powder burns on the target.

I like your thinking.
Yup, just 0.5MOA higher than the 105AM.

Surprisingly, nearly all of my rifles behave this way when I get it right at the reloading bench. A TTSX and a good LR bullet (usually an AM) hitting either the exact same POI, or the TTSX hitting just a tiny bit higher.

For conversation- The low shot was the fouler following a tube full of WO being swabbed from the bore. The next 2 TTSX bullets went into the same hole 1.5" above the fouler. 7WSM Montana and 140gr TTSX. 100 yards.

[Linked Image]

That group was immediately followed up with three 162gr AM fired at the next target over. Note POI compared to the 140TTSX.
[Linked Image]

When I work it just right, I can swap ammo completely interchangeably. Which one I grab simply depends on the application.
Posted By: Tanner Re: Sporter 243 A.I. Revisited - 02/05/13
Sweet shooter.

What steps are you taking at the bench to try to achieve POI intersections between different bullets?
Jordan,

I'm not doubting your experience, but most rifles I've owned don't behave that way. It doesn't matter if its a 223AI, 243, 260, 7-08, etc. I shoot a bunch of TTSX's and my POI hasn't been the same with other (heavier) bullets yet. This being with all things considered --low SD/ES for each load.

I don't know why, but I've seen a trend of TTSX's being up and to the left. Not a bunch, maybe 1" to 1 1/2" both ways.

Your thoughts on this?
I've been able to achieve these results with the last 6 rifles that I've bought, as well as several more that I work on and load for for friends and family. I can't profess to have any sort of magic secret up my sleeve, but I do a few things that may contribute to this.

- I always bed the receiver, and make sure the barrel is completely floated

- I always make sure the barrel has a clean crown

- I tend to use medium-to-slow burning powders for any given cartridge, selecting appropriate powders for both the lighter TTSX bullets, and the heavier target bullet loads. I push the light TTSX and heavy AM/MK/Berger loads fairly hard

- I use DBC in the bore of every rifle I get my hands on

- I first establish the max powder charge for the powder and bullet I'm using, with the bullet squarely touching the lands (except for the TSX/TTSX bullets, which I start, and usually stop, at 0.050" off the lands), and then I fine tune groups by varying seating depth. If seating depth doesn't give me enough adjust-ability in finding the accuracy node, then I'll adjust the powder charge down by a couple of grains in 0.5gr increments for anything larger than .223, and 0.2gr for .223-size rounds. This often consequently changes POI, and you can select a load that has the same POI as your LR load

I'm very picky about the accuracy and consistency of my LR loads, but if I can achieve 1MOA or under with a TTSX I'm happy, since I don't expect to use the TTSX for anything over about 400 yards

My methods may not work for every rifle, but I've either been extremely lucky, or else something is working for me to get POI intersections between TTSX and heavy target bullets. I'm not sure which grin

Thanks, good info. I have a couple of new rifles to play with. Maybe my experience will mirror yours with these guns...

Have you tried RL-17 in your Ackley or has anyone for that matter?

I get 3400+ with stupid accuracy in my wife's 22 1/2" vanilla .243 with the 80 TTSX and a max load of RL-17 (I "think" it's 45 grains by memory).

Imagine what your 3+ inches of tube plus your Ackley chamber may be able to achieve - grin...
I haven't. I don't have a lot of it on hand, and I have several pounds of IMR4350. I'd like to try it at some point, though. I'd not be surprised to see 3500+ with the 80TTSX and a max charge of R17...

'17 is one of the powders I plan to focus on with my rifle. I'll post all the results, and you can bet I'll try out some 80s-90s. This 80TTSX you guys are talking about has caught my eye.
+1 on the R-17 and the 80 TTSX. My sons SPS Varmint gets smoking velocity and outstanding accuracy with that mix.
Posted By: GregW Re: Sporter 243 A.I. Revisited - 02/06/13
I shot a ladder with RL-17 and the 80 TTSX with a Leupold 6x42 the first range trip I shot this combo with just to get a feel of accuracy /velocity potential.

At 300 yards, the last 5 charges went into less than a 2" cluster and the max was 3,400+. I think I even wrote "holy chit" on my range notes that day because of the accuracy/velocity combo.

Tuner, Im shooting the 80 TTSX out of a std 243 @3420 fps...super accurate, but I have not shot it at any distance past 300 yds...

Thanks ingwe. Mind if I ask what you're using to push it that quick? That's a smokin' load!

3420FPS from a standard .243 - W/80gr. TTSX is "SMOKIN" I too hope that recipe is shared!

Yall gonna talk me into doing another 243AI...well actually the pile of parts that I have accumulated is gonna necessitate it. I got a Short 700 a MCwoodie hunter with a red pad and a rock sendero contour 7.5T carbon fiber wrapped blank just laying around. Might have a jewell needing a home somewhere in some of the piles of junk. I don't need another 6BR or 6x284 right now, sooo. Probably do some scope swapping so I end up with leica scopes on both. I really like the leicas but hate being limited to 18 MOA of travel because of the zero stop.
Posted By: Tanner Re: Sporter 243 A.I. Revisited - 02/12/13
Do it up Eddy! Sounds like you've got a couple "decent" pieces to toss together... grin

Wish I had crap like that laying around! Laughin'!
I'm looking forward to putting mine together. Actually, I'd like to put two together. One light and one a little beefier. To be honest, I usually grab the 243 for deer season around here anyway. A 243AI would just make it more better...
Posted By: Tanner Re: Sporter 243 A.I. Revisited - 02/12/13
That Brux you just bought is saweeeet and I bet you could put a rifle together using it and have it come to about 8.5lbs all up if you are careful... kind of a midweight?

Two is better than one, though... grin

I will definitely be carrying mine on hunts next year, pending on how it ends up shooting.
8.5 or even 9 all up wouldn't bother me for the heavier rifle. The McMillan (Sako) Hunter would be a nice stock for that rig.

The light rifle would be a MR contour in an Edge....or maybe Faux Ti....somebody told me they didn't suck.

I'll have to go the heavier route first since I just bought the barrel. I'd be waiting a few months on the lighter barrel anyway.
Posted By: Tanner Re: Sporter 243 A.I. Revisited - 02/12/13
I really like the looks of the Sako Hunter, that'd be a great rig if you weren't going to do a bunch of steep hiking.

I like the faux-T.I. idea myself, too. I'm very interested to see what mine will weigh.


I hope you're stocked up on 105s!
I have a few (500ish) and will pick up more. LGS has a few boxes left. The 105's and TSX/TTSX's will probably be the only thing that goes down the tube.

I have plenty of RL17...for now. With the way things look now, I'm glad to have what I've got! I'm saving all my H4350 for when the 260 gets back.
Posted By: Tanner Re: Sporter 243 A.I. Revisited - 02/12/13
My tax return is going to be spent %100 on gunpowder... If I can get a good stock of 7828 and RL-17 I'll be good! I'm putting some major blind faith in '17, but what the heck... if it doesn't work I'll trade it or somethin'.

What are you doing with the .260?
Eddie F has it. He's giving it a coating/bedding job. I had a Douglas screwed on last spring and it shoots great. Decided it needed a little bling. Ordered a Ruger MKII Hunter (McWoody) and coating all the metal in graphite black.

It's my Faux Old School rifle! It should be coming back very SOON...
Posted By: Tanner Re: Sporter 243 A.I. Revisited - 02/12/13
Sweet! The Faux Wood and Blued rigs are awesome... the best way to use a wood stock is to make it a Mickey grin

Maybe someday I'll pour out the pennies to get sweet coating jobs, but my clown-school Krylon jobs will have to do for now... grin
Posted By: EddyBo Re: Sporter 243 A.I. Revisited - 02/14/13
I plumbed a 243AI last night. 7,75T sendero contour interrupted fluted Brux on a trued up 700 in a HS. I started trying to get a few out of the way so I can work on my own crap. Waiting on my buddy who owns the gun to drop off a bolt stop return spring, and a wyatts mag box follower and spring. Then it is off to birdsong for some Black T.

Jordan already told me he was getting me one. So you'll have to wait. He cant just go buyin' schit for yankees before he takes care of his distant Ontarian son.

BDL SS Take offs in .243 and 7 Sham-Wow sitting at the ready, and an Atlas waiting to rock. Gotta order some more, those DBMs are nice for the hundred and a half you shell out.

Looks nice! I'd go with a little more tube weight for balance with the DBM.
I've been pondering the same thing. Which is why I keep throwing the idea of the SAUM takeoff in there, as its a Mag contour.

I'll eventually screw them both together and find out for certain. But as Tanner mentioned earlier, my priorities are [bleep] laugh

I'll probably hack the green pad off and grind the stock down a bit so my sister and girlfriend can use it, too. It's got a 14" LOP currently, and that ain't going to work.

The whole point to this sako hunter was to be a rez build. Its got a 50$ barrel. I can't go putting a douglas, brux, kreiger etc on this thing...then it wouldn't be a budget build anymore laugh

It will be THE ultimate road hunting gun. I will patent it and sell it to Cummins 1 ton owners out West and in Northern Ontario by the thousands.

Very true, but the magazine weight (especially the Atlas type 2 10 rounders), as well as the Sako Hunter having much of it's weight aft will push the balance point back. The 6x42 and Talleys will help some.

I say try to find a SAUM/WSM action, and throw the 7mm SAUM barrel on there.
Working up loads in a vanilla 243 with '17 and the 80 grain TTSX. Not much of a long range load, but I'll conjure up something with the 105 A-Max as far as that goes. Going to have this rifle punched AI eventually, just need to figure out when.

No pressure signs whatsoever. Safely worked up to 46 grains of '17 thus far, might see how far I can push it for the sake of curiosity. Hunted with this rifle shooting 45 grains of '17, which pushed the 80 grain bullet around 3350 fps. I can vouch that the deer did not appreciate this load in the least. Accuracy was there, too. Shot two groups at 100 yards in haste after getting it on paper before the season. First was off a pretty unsteady rest and was 5/8" center to center. Second group was a CH larger than 1/4". I highly doubt that I'll be able to replicate the 1/4" group, but I'm not going to complain.

[Linked Image]
That's scooting! My hunting load with the 80TTSX is 44.5grs of RL17. I get 3350ish from a 24" barrel.

I tried a few at 45 and 45.5, but the accuracy node for me was at 44.5.
We'll see how things pan out in the accuracy department, I'm hoping it works out.

If not, I've got no qualms gunning my 45 grain load at critters.

Guessing is probably an exercise in futility, but 3150 would be my closest estimate... seems like moly really keeps the pressure down.

FWIW -- Barnes lists 45.5 of RL17 as their max with the 80gr TTSX.
Posted By: Tanner Re: Sporter 243 A.I. Revisited - 02/17/13
I dunno' if anybody else thinks this way, but it's tough for me to relate Barnes bullets with others when working up a load... meaning that sometimes I'll take a look in a manual, locate a given weight bullet, and use their data for another bullet (given that work up is involved)... but with TSX and TTSX, the charges just don't seem to line up, and sometimes it takes a bunch more or a bunch less powder to get where you want to be (maybe the shanks, or small bearing surfaces?)

Could just be very amateur handloading, as well... grin
One trend I've noticed with Barnes bullets -- they liked to be pushed. I've yet to find an accuracy node with any cartridge that wasn't near max using the TSX/TTSX.
Yeah, I'd say from the looks of it he's more than into the world of pressure. But, as one of my best friends likes to say don't let anything but fear and a bit of common sense guide you... wink

The Alliant site calls for 44/17 with an 80 @ 3362 fps. To date I've not found a load yet that wasn't pretty much top of the tier that was listed for them and I had no personal interest in going any further.

But, Powder River let er buck...

I've noticed similar results. For me they've shot ok with medium loads, and great when pushed to max pressure/velocity, in several rifles.

Agreed. 3500 with 80s would be pushin' it hard!

Very true, but the magazine weight (especially the Atlas type 2 10 rounders), as well as the Sako Hunter having much of it's weight aft will push the balance point back. The 6x42 and Talleys will help some.

I say try to find a SAUM/WSM action, and throw the 7mm SAUM barrel on there.


It's easy enough to just run a couple of AICS 5-round mags, which don't weigh near as much. I only use 10-rounders when shooting from prone or off bags.
Is it possible to remove the reinforement plate on the 5 rounders and get to 2.95" OAL or so? AFAIK, the type 2 10 round mags are the only mags designed for the longer OAL? Pardon my ignorance, I have a 223 AI with AI mags, but haven't really been around the .473 bf mags.
Yessir, it is possible.
Nice! Thanks. The longer OAL would be about the only reason I would personally run AICS mags on a sporter weight hunting rifle. The 5 rounders are much more appealing for such an application. It would be really nice if they made a flush fitting 3 round mag.
Yeah, that and the reliable feeding compared to the factory BDL problems that sometimes pop up. Your numbers are pretty much bang on. With the plate removed, the max OAL in my AICS mags is 2.990-2.995", depending on which mag you measure. Knock off 0.020" for reliable feeding, and you end up with a max usable OAL of around 2.970".
Thanks Jordan. The feeding issue is why I went with the AICS mags on my heavy 223 AI. Those centerfeed mags feed 75 Amaxs smooth as can be.
So lets say I just bought a new Stiller Predator action and 6mm Brux blank. Which bottom metal (or none -- ADL) should I be looking at? I'm not opposed to use something that affords longer OAL. I can have the chamber throated to my liking, but I don't want to rob case space either.

After the first barrel is burnt, I may want to jump to 260 or 7-08. Kinda looking post 243AI too. You never know....but now is the time to consider options.
Posted By: Tanner Re: Sporter 243 A.I. Revisited - 02/18/13
Oh man... custom actions and everything. In case you didn't notice... this thread is for beater rifles, not nice ones laugh

What's the length on those Predator boxes? 2.85"ish? I'll be the dissenter and say that I really like ADL setups (105 at 2.8" puts the base of the bullet in a pretty nice spot), but in all fairness, I have never run a really nice DBM like the one Jordan is using.
I bought a 700 ADL that was going to be the project. Then I stumbled across the predator. The action doesn't come with a box, just the cut out. They do offer options, but I don't know if I want to use theirs.

I like the ADL set up too. That's why I'm asking. I've never used a nice DBM either and wonder if something could make it more better!
I'm with ya Tanner, I'm all about ADLs (BDLs don't bother me too badly) for a hunting gun. DBMs freak me out a little, I really would hate to try to chamber a round on a hunt and find my magazine missing. Those babies aren't cheap, either.

Side note: We had a guy lose his factory 700 DBM magazine on a hunt. He didn't have a spare. Had to backtrack and fortunately found it at the last glassing spot. Dumb.
Posted By: Tanner Re: Sporter 243 A.I. Revisited - 02/18/13
My old .280 had the factory DBM and it always kinda' freaked me out. I considered glassing it in, but it never really gave me real trouble. Much happier running a blind-mag 7RM now, however.

I know it's been discussed ad nauseum, but what is everybody's final verdict on a Wyatt's box in a SA 700 BDL setup?
I'm digging the one I've got in an ADL.
If money and availability were no concern, then I'd be tempted to try out the APA bottom metal. A lot of guys really like the design of that unit, and it will take AICS or AW mags.

If you're running the 105AM, then an OAL of about 2.820" puts the base of the bullet's bearing surface right at the base of the .243AI's case neck, so a mag box that measures 2.840" would be plenty.

Without having the 140gr Berger VLD or Hybrid in my hands, it looks like, based on calculations, an OAL of 2.977" would put the base of the bearing surface of the 140 VLD at the base of the neck on the .260 Rem. That means that if you're using AICS mags, you'll want to remove the reinforcing plate in order to get enough space for that 2.977" OAL. You'd have to throat accordingly, of course.

ADL isn't a bad way to roll for a hunting rifle, but it's nice to have the M5-style BM and AICS mags for a rifle that is used for both hunting and a lot of steel/paper.
Tanner-can't recall for sure what it was but it seems to me that SU35 had some issues with the Wyatts on a short action.

Dober
Took a little tweaking of the magazine spring, but once I got that done, my Stiller/Wyatt combo feeds as well as any factory 700 I have ever had. Edited to add that, IIRC, the internal length is 2.995", pretty nice with VLDs...

I have no idea of tellin' how fast the 80's are going. I'm really anxious to run it over a chrony.

Looks like from my 500 yard drops, the 105s are going right at 3150.

My old 3-9 is kind of lacking, optically. Might need to upgrade that.
I get 3350ish from 44.5grs of '17 in a standard 243 (24"). I bet you're pushing better than 3500...
Tanner, I'm running the same load as your Berger VLD load. Shoots pretty good in mine. The 80 gr ttsx are going to get worked up when the weather gets nicer.

No pressure signs whatsoever. Safely worked up to 46 grains of '17 thus far, might see how far I can push it for the sake of curiosity. Hunted with this rifle shooting 45 grains of '17, which pushed the 80 grain bullet around 3350 fps. I can vouch that the deer did not appreciate this load in the least. Accuracy was there, too. Shot two groups at 100 yards in haste after getting it on paper before the season. First was off a pretty unsteady rest and was 5/8" center to center. Second group was a CH larger than 1/4". I highly doubt that I'll be able to replicate the 1/4" group, but I'm not going to complain.

Figured that load was very likely near maximum in that rifle, and it appears that it is from your QuickLoad data. I should probably go ahead and get a copy of that. Going to load up some more TTSX's with 45 grains of '17 and reevaluate everything. Once we get warmer weather, I will be sure to ascertain as to whether or not this load is safe in higher ambient temps.

As someone mentioned, Barnes lists a maximum in their book as 45.5 grains and that is the data that I used to work up to that load. The QuickLoad data with 45.0 gr RL-17 is spot on with my empirical results.

prairie goat - FWIW, my rifle has a 24" barrel and the COAL was 2.755", would be curious to see if that changes the QL data by much or at all.

Leave it a 243. BTDT on the factory barrels set back and made AI. Not worth the cost and time for 100 fps. Won't see any difference in the field. Trimming is about eliminated. Big whoop.

If you are rebarreling, go for it.

I'm in support of this as well. If this barrel hadn't ALREADY been punched AI, I wouldn't have gone that route. But, it was so that was just an added bonus.

As far as I'm concerned, a vanilla 243 will drive the 80s to 3350(ish), and the 105s a bit under 3100. That's a lot of smack from 45-49gr of powder.
Yeah, it's one of those deals that seemed like a good idea at the time, and later I kinda scratched my head and asked myself "why did I do this"?

It was about this time of year, 11 years past that I sent in a Sendero 25-06 and a KS mountain rifle 280 and had them punched AI. Had some fun with them, but I didn't gain anything - and spent at least 400 bucks getting them both set up as Ackleys by the time the gunsmith was payed, rifles shipped, and new dies were bought.

Like I said, worth doing if you need a new barrel anyway, and if you're not set up to load for the rifle in the first place.
Posted By: Tanner Re: Sporter 243 A.I. Revisited - 02/24/13
For that much coin, I'da just had a new tube screwed on one of them! laugh

I will say that if you've got a gunsmith buddy that'll punch it out for a 6 pack or whatever, then it'd be a good idea. But, there are a few benefits to doing it besides the new chamber... Jordan had his throated in accordance with his 105s when his was punched out (I believe?), and that's a huge part of this 243 AI and 700 action equation...

I think it's almost time for me to order up a Douglas for this rig laugh

I'd be thinking more like:

6 Rem AI

In that order.

Did you compare it the Leupold 3x9 AR Mod 1?

Mil/Mil does take some getting used to if you learned MOA/MOA, but it is great once you get used to it.

I checked out one of the AR Mod 1's at a Sportsmans. Definitely a nice little option for a lightweight rig, but I wasn't too fond of the BDC numerals with the Mil designations written really small below. And it doesn't have hash marks to designate which turn you're on, so those kind of blew it for me.

If a 10T would do what you need I could get you running fast and cheap with a SS rock.
Posted By: Tanner Re: Sporter 243 A.I. Revisited - 04/07/13
I appreciate the offer Eddy, but I don't know if a 10T will spin the 105 A-Maxes like I want it too, and that's really my main bullet of choice in this rig. I've heard of some doing it, but I'd rather just do it right the first time.

I think I'm going to order the #3 Shilen and fling a package your way. Trying to see if Kenny can give me an idea how long the throat is on the one you built him.
Posted By: EddyBo Re: Sporter 243 A.I. Revisited - 04/07/13
At your altitude I think the 10T would do the job, but here at sea level they are iffy. I kinda like to be better safe than sorry myself, so your probably doing the right thing. I can tell you that 105 scenars will jamm and feed with my reamer.
Posted By: Tanner Re: Sporter 243 A.I. Revisited - 04/07/13
The 105 Scenars will jam and feed from a 2.8" box?
MOA/MOA and mil/mil are the same thing, they're just different incremental angular measurements. You already know that.

Simply put, 0.5 mil is about 1.75MOA, 1 mil is about 3.5MOA, 0.1 mil is about 0.3MOA, etc. The only time you will likely even have to think about that is when holding off for wind or elevation. If you're dialing it in, just tell your ballistic app to spit out the corrections in mil's, and twist the knob to the requisite marking wink

FFP does take a little getting used to, but I have a feeling you're going to love it once you get your head wrapped around it.
Posted By: Tanner Re: Sporter 243 A.I. Revisited - 04/07/13
I'm getting the mil/MOA conversion down pretty quickly, but it's still just a little odd seeing .10th mil clicks vs. 1/4 MOA. I AM loving being able to see misses on the mil reticle and not have to convert it back to MOA to make an adjustment on the turrets. Shooter's already been converted to MILs for this rifle.....

Yep

I would tell you how a 105 A-max would seat but apparently I sold them and cannot remember doing it.
Posted By: Tanner Re: Sporter 243 A.I. Revisited - 04/07/13
They're only .013" longer than the 105 A-Max, can't imagine that the ogives are much more than a blonde CH different?
If you have a bullet comparator, have Eddy give you the base to ogive measurement for the scenar and you should be able to load an Amax to the same OAL and make the comparison. That should tell you if it will work or not.

How does the 3-9 SS do at longer distances without parallax adjustment? Non-issue?

Posted By: Tanner Re: Sporter 243 A.I. Revisited - 04/07/13
Wish I had a comparator around, that'd make things easy. I do believe Scenars have a longer ogive than the A-Max, so the 105 should work from the box pretty handily. Maybe Eddy will find an A-Max or two and give me an idea.

I shot the SS 3-9 at 900 today, and I will say that the reticle was a bit hard to use with the way the sun was shining. Very clear and bright though.... might have to mess with the focus a bit and see what happens. The no parallax adjustment doesn't bother me at all.
Posted By: EddyBo Re: Sporter 243 A.I. Revisited - 04/07/13
Do you have a way to measure base to ogive on a round loaded to the dimension you want? You need to get one of those sinclair nuts for measuring if you do not have one.
Take a steel caliper and set it at bullet diameter. Score the bullet at the ogive and then measure the distance to the score mark. Can't take credit for the idea. Mule Deer's, IIRC.

Got a few measurements, but I don't know how good they are...
Posted By: EddyBo Re: Sporter 243 A.I. Revisited - 04/07/13
I ran out in my shop (Well limped my crippled up arse out there) because somewhere in the back of my mind I remembered I had another 243AI out there. I checked the twist but it was a 10T as well frown

While out there I took some pics of that 243AI and of the bullet along with some measurements that could help you out. The little piece of barrel stub on the bullet is one of the greatest reloading tools ever. I have started making one for all the guns I build.

Here is that 243AI cute little thing but it needs a shortened action screw. It has a pillar in there that has a bolt holding the gun together, the screw hanging out is just hand tightened into the screw that is halding the gun together.

Here is the dummy round inserted in the doo dad after I spun it to make some marks on the bullet.

Here is a pic of the dummy sitting in a SA mag box I keep around for size checking.

Here is the bullet being measured with one of those sinclair nuts on it. Subtract one inch to know base to throat measurement.

Here is the COAL of the dummy round with the 105 scenar.

My 105s are at 2.18 when seated to 2.805" COAL. Does that make any sense at all?
Posted By: EddyBo Re: Sporter 243 A.I. Revisited - 04/07/13
Yep. If it will feed at 2.805 you should be good to go.
Posted By: Tanner Re: Sporter 243 A.I. Revisited - 04/07/13
Did some calculating and it looks like that reamer will jam A-Maxes at 2.815".
Posted By: kenacp Re: Sporter 243 A.I. Revisited - 04/08/13
Looks like with 105Amax"s to the lands is 2.768"
Damnit I've wanted a 22-250 for a while but all this 243 ai talk has got me wanting one, good new is the donor is staring at me, leaned on the wall right now. Is It bad to want one with a #3 in an Alaskan at 23 inches
Posted By: Tanner Re: Sporter 243 A.I. Revisited - 04/08/13
Sounds about perfect to me.....

Kenny, any idea how close 2.768" puts the ogive to the case mouth?
Posted By: kenacp Re: Sporter 243 A.I. Revisited - 04/08/13
Sorry,I don't have any way to get an exact measurement.
But,with my brass and 105Amax looks to be .100"
Here's 1000 words for you, Tuner...

Thanks man, I was actually going to PM you to see if you could hook a brotha' up with a picture. Looks like I'll be just fine.

Up to refresh a classic thread that has lots of EddyBo in it.
Great read, thanks for bringing it back
