I want to order one of these for prairie dog and target shooting? I wanted a 1:8 twist in a 18 or 20" version? Also thought of a 1:7 twist rate? Any suggestions which is more ideal for twist and length for this type of shooting?

I'm not interested in stuff that heavy, but WOA is now making their Competition Uppers (which can be nearly identical to the Varmint version & take an optic) with Shilen 5R Ratchet rifled barrels, which IMO, is an upgrade to their standard Wilson blanks.........for a little more money.
I talked to them recently to try to get them to contour one of those blanks for me into an 18" SPR configuration, but they said they were only going to use those blanks on the Competition uppers for now so they would not do it.
As for length & twist on the varmint rifle, if it was me, I'd go with the 1-8" twist, 20" barrel............actually, I'd go slower on the twist if it was available for the reason that I'd only be shooting lighter bullets for varmints, if that's all the gun is intended for.
But you do get more versatility for heavier bullets with a 1-8" for hunting bigger stuff too. You will be good to 77-(maybe)80 grain bullets with the 1-8".

MontanaMan, the Rainier SPR Ultrmatch we were discussing the other day is the same Shilen blank with 5R ratchet I do believe.

MM, I will take a look at the Shilen 5r Upper. Thanks for the info on it.
I see they offer it in 1:7 twist rate for the competition, I wish I could get that model with the Varmint Handguards. Guess I could call and ask them?

You seem to be pretty good at finding those steals...........seems like I remember you picking up a new Leupold MK6 (or was it a MK8) for a go-to-hell price not too long ago.  MM

MM Maybe an 80 with an 8 twist 20 inch? My buddy runs 9s on purpose with 80 bergers and has never had an issue...Although I lean the other way. I"ve never seen a true 8 that would not stabilize an 80. Maybe a 16 inch possibly. The 8 is an awful versatile twist. I"m with you though, if all I was shooting was light, I'd have no problem slower, though I have no reason why I'd want to limit myself to light bullets.

I'd suggest the 20" sdm barrel. I assembled the upper myself, easy enough. ![[Linked Image]](http://forums.accuratereloading.com/evefiles/photo_albums/3/4/4/344100033/6731061612_2A820DF52BF175ACDB95B77752DCE849.jpg) The fluting makes the barrel balance perfectly and I prefer the 20" tube to reduce muzzle blast. I think I went with the 1-8 twist, it's been a few years and I'd have to check the barrel to confirm.

Nice! I'm thinking of running 69 SMK for the AR. Not sure if the 80's will fit the magazine? Maybe run a 75 grain Amax or similar for all around varmint shooting, still thinking but really want to start with the 69 SMK.

The Hornady 75 gr hpbt is more amenable to AR mag constraints. You might also want to consider the 55 gr v-max for the smaller varmints. Something to be said for speed and soft bullets

The 69 SMK (& 77 SMK) will fit the mag.
The 80 SMK or Berger & the 75 A-Max will not w/o some of the ogive being into the neck.
Those can be loaded singly if seated long.
Berger also makes a 77 OTM Tactical bullet with a different ogive that will fit the mag & not be seated into the ogive, FWIW.

80's are single feed only.
75gr. A-Max will have the ogive inside the case neck if you want them in the magazine.
The new 73gr. ELD Match bullets are supposedly good for mag length. I just got some but haven't had a chance to load any yet.

MM, the Rainier barrel cost me $225 in the wrapper so a pretty good deal. The Mk6 3-18was $1350 NIB so better score there.
Both items live together on the same rifle now and I'm beyond happy with them both.
77 OTM's shoot well in it but the 69 steals the show for all around. 55 vmax didn't suck either

You should have a guilty conscience when you go to bed tonight, stealing stuff at those prices.
I'd probably go ahead & use the Ranier Shilen barrel on my gun but they don't make it fluted & WOA's (Wilson)fluted version is about 7 oz. lighter.
Just haven't decided or bought a barrel yet, probably just go the WOA route.

I don't have any of those yet, but I believe the ogive is the same as the 75 BTHP which are fine for mag length & have shot very well for me. Probably won't get any of the new ones for a while as I have about 3K of the others & the Bergers on hand now. I think Wareagle 700 is doing some testing on the new tipped Hornady's now. When he get through, maybe he'll let us know how they work for him. MM

Hoping the 1:8 will do the 69 grain SMK or even a 55/60 V MAX. I don't want a single shot AR for my use. I think I will be able to get the 69's to shoot out of a WOA barrel? I will have to see if my hypothesis is right?

1:8 should be plenty for all of those. I think you could get away with 1:12 with the 55 v-max.

69s generally stabilize out of a 10 twist, at least the non tipped ones did. 9 for dang sure.
55vmax should go 12, not sure about 14, that might be slightly iffy.

Thanks, I want to have a little versatility in case the rifle is finicky so between 60 to 77 should get me something with decent accuracy, even though a little "big" for poodle shooting.

I prefer something like the 55 Vmax for maximum aerials on pasture poodles and prefer the improved ass of the 69 and 75 bthp's for coyotes and the like. That said the 55's are no slouch on coyotes and the 69 and 75's fling parts just fine on prairie dogs and ground squirrels.
Any of them will work great assuming proper insertion.

I've got a complete rifle Jp upper (never been shot) with daniels lower, with the geiselle two stage trigger. Never been shot, 20" medium barrel. I'll sell you for $1025.00 shipped to your ffl. If you're looking for accuracy this will be hard to beat.

John Holliger makes as good an upper as anybody. Nez Rongero built the uppers for the Presidents 100 winner and 3rd place I believe at Camp Perry this year. The Texas team also set a new record. Nez uses Shilen 8 twist 4 groove ratchet barrels. Shilen has never made a 5R barrel.

John Holliger is a first class builder and person. He recently built this for me. It's going on a venison tactical rifle. All the parts are integral. ![[Linked Image]](http://photos.imageevent.com/lucky/stillerxtrifle/large/barrel%2045554.jpg)

I have a WOA Varmint upper and love it.
While on a coyote hunt around New Years my friend I was hunting with had just switched out his conventional upper with a side charge upper, after using his gun for a day it made a side charge a must have for me. only problem with the swap is that you wont get the barrel nut off a WOA without buying a barrel nut tool from WOA for $39 it is unlike any other barrel nut.

Put the order in today on a WOA Upper 1x8 twist SDM Fluted Barrel with varmint upper. Now just need to pair it with a lower? Any suggestions on a good lower for this?

Sorry............wasn't thinking.
You asked about a lower & I was thinking upper.
Lower doesn't matter much; I've had good fits with Aero, PSA & Anderson.
Aero has an adjustment screw to help tighten the fit to the upper if needed.

Lowers are pretty much generic IMHO. Not nearly as important as the barrel etc...
I've set some range records with an EA lower.. the cheapest there was around in the 80s IIRC.. fugly but workable
I"d spend the money on the best trigger you want. And the rest is just what floats your boat, stock type etc..
Whats printed on the side of the lower isn't goign to matter IMHO.

I have a Wilson 20" fluted varmint barrel w/1-8 twist on my coyote gun right now and it will put 10 shots at 100 yards into a 3/4" hole if I do my part correctly. I had a 24" Olympic Arms SUM barrel that would do better but carrying it in the field was a pain. I only shoot 55 grain V-Max from Freedom Munitions and have had very good luck with their product.

Going to unleash this thing on a prairie dog town! Thinking a Stag or Spikes lower and maybe do a PRS Magpul stock with a Geissle Trigger.

Or you can do a Magpul ACS stock. That is what I use so I can collapse it for easier transporting. And to not start a trigger war, you might want to look at a Timney single stage. I have the 3.5# and really like it. But there is also nothing wrong with a good two stage either.

I wouldn't consider an ACS (or my preference, the ACS-L) an adequate substitute for the PRS in that role; they are not at all the same type of stock and don't have similar features. Esox, have you seen the small monopods you can attach to the PRS stock, to take the place of a rear bag? They aren't cheap, but make a lot of sense for the usage you have in mind.

Yes, for a dedicated LRP type of rifle, the PRS is a great stock if you can put up with the weight & the cost............sounds like that rifle will be heavy anyway, so a little more doesn't matter much.

Not planning on carrying this rifle for miles, so a couple pounds won't hurt and it will add stability for shooting. I haven't seen the monopods but will look into them. Thanks.
