Folks,

I've been extremely interested in this cartridge for a while now aand am impressed with what this package can do in a short action.

It seems like nobody makes a rifle chambered in .284 or at least I cannot find any.

I've no idea what it takes to screw together a rifle or to have a gunsmith do it for me...

What exactly would be the steps to take and the approximate costs of putting a rifle together in .284?

This will strictly be a hunting rifle and no more...

Any blueprints, associated costs and ideas for putting together a .284?

Thinking 24" synthetic stock, 2.5-8 Leupy in TLW for starters but this is negotiable...grin...

Appreciate it tons....-Greg

Greg-if you've got the Cheddar make it easy and call NULA.

Mark D

Do like I did. Buy a 7-08 and send it off for a rechamber.

Dave

The easiest way to get a 284 is to rechamber a Remington 700 LSS MR or 700 Ti. Although I have been shooting the 284 since 1974, it became just a case donor for me when the 270 WSM, 7mm SAUM, and 7mm WSM were born.

Jeff

I had a Model 70 SA Stainless, 23" Pacnor tube, Bansner stock.....it was a hell of a nice rig....not sure why I sold it...lol

I have an LVSF in 7-08 that I've thought long and hard about re-chambering to 284, but I may just keep it as is, for feeding issues alone....

Smart move Rack!

Mark D

I dont have many of em....but every once in a while one comes along.....

So ya'll thinking a .284 is a bad move as it does not offer a lot over a 7-08?

If this is the case I already have a .260 and you can compare this with a 7-08 as well....

Rechmabering sounds the best as that kind of cheddar, Mark is not available at the current time...grin.

How much does a rechambering usually go for roundabouts?

Gmoney,
The 284 does offer some gains over the 7-08....just depends if you want that extra little bit or not. Its a great cartridge and overall I enjoy it a lot. I also like my 7-08 a ton, and like the fact that I CAN buy good factory ammo if needed.
The only reason I wouldnt rechamber my LVSF would be for feeding issues, as some of them can be a problem it seems. I think the 7-08/260 does it nicely, so it might be for personal kicks to go to 284. Really if you wanna compare, a ton of cartridges are really close to one another.....
Tough choices.....but still dont overlook the 284 if you have the hankering....

I went the Remington 700 SA Titanium 7mm-08 route to get to 284 Win. Mine is still very early in the works. Basically 280 Rem in a short action.

Exactly the attractiveness from this end....

Definatly an attractive cartridge.....

OldCenterChurch,
How well does your Ti feed the 284 round?

It's not even that far along yet. Still in the phase of collecting the parts.

The 284 is a very good cartridge. When I had mine made, I did a lot of comparing of it with the 280, and decided on the 284 cause I like the case. Both chamberings give the same performance, I just liked the shorter case. The thing is accurate too. A 284 on a SA is the best route you can go in a 7mm, with a non-belted case.

By chance I had a 284 made up in the late 70s. I had a M77 short action in 6 mm rem that was shot out. I went to Harry Lawson and asked for an inexpensive rebarreling option. He suggested rechambering a new takeoff Rem 7 mag barrel. I shot the heck out of that rifle as it was my only one at the time. The Ruger had absolutely no feeding issues. The threads of a Rem barrel are the same number per inch as a Ruger, just slightly smaller dia. Approx 1/2" of setback is required to rechamber to 284. The barrel is slightly heavier being a magnum barrel. I am on barrel #3 since then.

Used to shoot 140s and now shoot 120s. Had the magazine lengthened to 3" and it sits in a discontinued Ruger Ultralight stock with a 3-9 x 40 VX II with S and K Rings. Weight is 7 1/2 lbs. Moly coated 120 nos bt and RL-15 yields 3325.

Go forth and make one if you want it, you'll enjoy this case.

I recently looked hard at the 284 win, it really is an excellent cartridge design and makes great use of the short, fat design. NULA chambers lots of rifles in this cartridge. In the end, I was able to cool my fever and I just built another 257 bob. For me, I am just too tired of losing interest and money in rifles. the 7mm-08 is so close that you really have to want a 284.

my three sons all have 257s. If I had to do it all over again, i would have build three 7mm-08s. I could olat them with 120 until the get bigger.

I'm just thinking a .284 will go mighty fine with my .243 and .260. I like to be a little different, and I was when I first acquired my .260...Now it seems everyone is picking up one ans shooting it after the realize what an awesome cartridge it is...

In a lightweight, short action package shooting 160's at 2850+ for anything up to and including elk one day hopefully...Looks like RL-19 would be an ideal powder...

Sounds like I may get my hands on a stainless 7/08 and get a rechambering job....

As far as being similar to a 7/08, 257 Bob, you are correct sir...but that 100fps gain in every bullet weight and even more-so with the heavies to me is a big difference, especially shooting across canyon...

As I said previously I'm not exprienced in what all entails a rechambering....

Someone want to give me a basic idea what occurs in a rechambering before I do my own research?

What kind of specifics would the crowd suggest for a starting point in putting together a .284?

Much appreciated fellas...

-Greg

Find an older Browning or Ruger in 284.Shoot it for awhile to see if the cartridge trips yer trigger and then go from there.You won't lose much if any when you go to sell your "test" rifle.

I'm trying to rebarrel a Rem 600....

I"m between 7.08, 7.08 AI, and 284

Pluses and minuses comparing? Is the AI round a better feeder at the same speed as the 284?

I have a 788 to rebarrel also, but was thinking of going 308 and keeping this 600 a different caliber. There is also the chance that the 788 goes to 6.5x284 for long range shots....

Jeff

I would encourage you to get a 284 if that is what you want. I always tend to lean towards off-the-wall stuff too. If I were leaning toward another 7, I would have me a 7 SAUM made if I couldn't find one.

I say, if you want one...get it done!!

If anyone has a 7 SAUM....let's talk.

the 284 is cool for sure and an excellent design. my local shop has 284 ammo on hand and it is very tempting to build a rifle around a box of ammo. If it were me, I would pick the action of choice and send it off to it&d custom gun. they could send you back a new 284 in the barrel material and dimensions you desire for roughly $400. they have done three for me in the last 6 months. the latest was the 30-06 that can back 257 roy.

Speed comparisons anyone?? 7.08AI vs 284?

I don't have any 7-08AI loads available. But, you can get very close in comparing the two by adding about 5-10% to the standard 7-08 velocities comaping those to the standard 284 in your manual. The 284 velocities are very close to the 280 Rem, close enough for practical purposes.

Don

My best SWAG is that they would be pretty much a wash.

The big diffs would be dependant on different lots of powder, different tubes etc more so than any big diff between rounds.

I would personally do the AI well b4 a 284 even though I do really get tickeled by the 284. But I've been there done that and bought the t-shirt and hope to go back.

But...I am a gun looney so one never knows. A while back I had the wet dream of taking a 7/08/Montana to a 284.

Later

Mark D

I wanted to sneak a 284 into a K. 84M. It would feed but the action is just too small otherwise. While the 284 is a cute round its not all that special when held up to the light what with the rebated rim and its lack of popularity. If it must be a 7mm then the 7-08 is just fine for lightweights and the others will fill the longer actions.

I read that NULA discourages the 284 due to feeding problems?

Consider a 7-57 AI for 3" magazines!

Zander's had some Remington 7 stainless synthetics on close-out for $428 wholesale the last time that I looked. I bought 1 and installed it in a Remington 673 factory laminated stock, but haven't had time to play with it yet.

I have discussed the pros/cons of the common short action .284" bore cartridges off-line with 'Stick and he was of the opinion that there was about a 200 fps incrimental difference between each cartridge in the 7mm-08AI, 284, and 7mm SAUM sequence. Since he had rifles chambered for all 3 cartridges, I'd be will to accept his professional testimony on this issue.

Jeff

Please explain how there can be 200 fps between a 7-08AI and a 284?

I can't see that either. I'm betting it's going to be a wash at best between the AI and the 284. I have two 7-08's (22" and 24") and a 26" barreled 284 for my T/C Encore. My max load for 140 gr Nosler Accubond gets right at 3000 fps in the 24" barrel, 2940 fps in the 22" barrel. The 284 goes 3120 fps using another max listed load for the same bullet (Hogden lists 3079 fps for a 24" barrel with this load). Not really all that much difference when you consider the difference in barrel length - the 24" 7-08 is right there - the 284 also takes 6 gr more powder to reach that 70-80 fps advantage - usually not going to be worth it. However, when the weight of the bullet goes up to 150 gr TSX, the 284 starts generating some separation. Velocities right up to and just over 3000fps were obtained with the 26" 284 - all within the published load data limits - 2966 fps was the published velocity for this load. The pulished number is 120 fps more than I can get with the 24" 7-08. One thing to note is, Hodgdon now lists COLs for the 284 that are not going to work with most short actions. IMO, the only time the 284 is really going to do much more than a 7-08 is going to be when a Wyatt's box extender is used or, if one of the longer short actions (i.e., Winchester) is used. I bought that 284 barrel just to see how I liked the cartridge. I like the 284, but the 7-08 is pretty close to it. It does provide a little more confidence for use on larger game, and I will probably someday get one made. If you're looking for a mostly deer gun, but want to feel adequately gunned for that occasional elk hunt, then I'd pick the 284. Hope this helps.

284 would be normal dies, 7.08 AI specialty.... as much as I like the 6.5x284 round......Rebated rim hasn't hurt it one bit in 1000 yard shoots. So the case itself is ok. And will be no shortage of brass even if I have to neck up...

I suspect the 7.08 AI is gonna get the nod.... But I"m not done researching yet.

24 inch tube?

I'm probably wrong on that, as I am relying on my memory. Maybe it was a 200 fps difference between the 7mm-08 and 284. BFD. IIRC, the 7mm-08 has about 54 grains of H2O capacity, while the 7mm-08AI has about 58, and the 284 has about 66.

Edit: The only 7mm-08 rifles that I own are Savage 99Cs and they are too valuable to shoot, so I don't. I don't, never have, and never expect to own a 7mm-08AI. I currently have a dozen or so rifles in 284, but again they are mostly Savage 99s and I have very little interest in shooting them. The only 284 that I shoot regularly, which isn't too regular, is a stainless Remington 700 that was rechambered from 7mm-08 to 284 and installed in a 700 LSS MR stock.

Jeff

Jeff,

How much did that rechambering job set you back if you don't mind, and do you have feeding issues with your .284?

I'm guessing you like what the .284 brings to the table?

Appreciate it....

I bought a used Clymer reamer for $30 and did the rechambering job myself. 'Gotta have some justification for paying rent for space to keep the Bridgeport mill and the Delta lathe.

Unlike some folks, I've never had a feeding problem with the 284 in a Remington 600/660/7/700/722 action. If I do, I stone the feed rails to smooth the sharp edges and then they feed quite nicely. The only rifles that I've ever had 284 feeding issues with were a few Winchester 100s, which would feed with some magazines but not with others that appeared to be exactly alike. That said, I'm sort of a 1 shot man, so the ability to cycle a full magazine as fast as I can work the bolt is lost on me.

I sincerely wish the 'Stick could answer the 7mm-08 v. 7mm-08AI v. 284 v. 7mm SAUM questions for himself, but he can't and I'm not sufficiently motivated to dig up our correspondence on the issue.

Jeff

Savage 99:

Not sure if Melvin discourages getting the 284. I have read on several occasions his best seller for that length action.

To continue: A friend recently agonized over the 7-08 vs the 284 when he ordered his NULA. Melvin said unless my friend was willing to neck turn the 284 brass don't do it. 284 brass necks are a bit off and while they shoot quite well in sporter rifles I think a tiny bit of neck turning can make the neck tensions more consistent. Of course one could get some 6.5-284 norma and neck it up to solve that issue.

Why can't a 284 chamber take the factory brass or ammo? Lots of cases vary in other chamberings as well.

I don't see many ULA's here. A outdoor writer by the name of Hall had a ULA 284 in Vermont. It was his favorite rifle. At the time the light weight did not matter that much to me.

Looking in the dozen or so reloading books I had, I found that the AVERAGE increase in bullet speed between a 7mm-08 and a 284 to less than 100 fps, when similar barrel lengths were used.

I have a Remington Ti, and the idea was intriguing.

Then, for me, the cost factor, the difficulty getting brass easily, the fact it would be hard to get factory rounds if I wanted to, and most of all - the fact I can throw a bullet as fast as that difference, convinced me to leave well enough, alone.

It would amount to close to an an inch flatter trajectory - at 400 yards.

Everyone has different thoughts though.

FWIW
In my 284, in R77LA, with 20" Shaw barrel, taper bored .0005", chrony 6' from muzzle, I get:
120BT / 52.5/RL15 / 3150 fps
139SP / 55.5/I4350 / 2900 fps
150NP / 49.5/RL15 / 2900 fps
160NP / 54.5/I4350 / 2850 fps
For brass, get on the waiting list for 500 pcs (if not in stock)thru one of the outlets. I use 284 brass in 284 and 6.5x284 and have no problems---last lot received last fall.
mrk

Yepper you pretty much covered my thoughts as well Brian.


Mark D

A friend had a M7 barreled with a 23" Hart that was fluted and chambered for the 7mm-08 AI by his BR smith. The rifle shoots very small groups and the velocity is up there.

The 284 never got off the ground. The 7mm-08 is quite popular. This particular discussion was tangent with a 7mm-08AI vrs 284 comparison for a moment. To each his own.

Guys- two things.
Most manuals are soft on the loads for 284 and a 284 case is within a few grains of a 280Rem capacity, basically the same.
So do you think a 7-08 is within 100fps of a 280Rem?

See this...

Here are the targets that he sent me. The 120 gr load lists 3150 fps over the chrono!

This man was the 5th ranking Br. competitor (for score).

This is what I was thinking....
I'm no expert by any means, I'm just going by what my manuals say and word of mouth...
Seems to me there is much more than 100fps between the 2, especially in the higher bullet weights...
To me this is a lot when we're talking about a short action, no magnum comparison...

My manuals list a top load in 7-08 with a 139 with H4350 at 2906fps with 55,721PSI..
Same manual lists top lod with .284 with a 139 with RL19 at 3075 at 53,500PSI...

With a 160 in 7-08 I've got 2684 with H414 at 58,185PSI...
With a 160 in .284 I've got 2888 with RL19 at 54,600PSI...

Like I said, I'm just asking questions as well but would love to hear someone who has chronied both the 7-08 and .284....

Greg-what were you using to measure your pressures?

Thx

Mark D

Ya know, everyone touts bullet drop. Frankly who cares about bullet drop? Thats so easily overcome correctly and easily.

Wind drift is another issue, I"m good at high BC numbers in 223 wind drift. Not good at anything else. Generally though you boot the same bullet 200 FPS faster, its a fairly significant wind drift number in my mind, especially further out. Wind is the iffy factor, not drop, IMHO.

I'm really rolling towards 284 now, the AI round almost had my vote but recent discussions and reading, especially that feeding can be overcome(I saw a few XC rapid fire bolt guns in 6.5x284 some years back-- but they were barrel burners-- but it tells me feeding can be handled...)

Jeff

I'm really sold on the 284 case, so much so in fact I prefer that case over the short mags. One more in the belly and a slimmer stock to boot.

Mark, Those pressures are out of a load book, probably Alliant although I can't be sure but that's the way I read his post.

Greg,
Meant to add I have not chrono'd the 7-08 but will and have chrono'd the 284. For mine, max was
120BT's at 3200
139's at 3000
150's at 2900

The 150's were of interest to me but sold it prior to further investigation.

Dave

Hey Mark...
They were out of a Lee reloading manual published in '04...

However, consulting Hodgdon's website I'm getting the exact same loads and velocities for each caliber but the pressures are in CUP...

Not sure on the conversions on these FWIW...

Figure I'd quote the pressures along with the velocites....

This thread really makes me miss the two .284's (1- Ruger Tang safety 1-Browning Micro-Medallion) I traded off.

HBB

This thread makes me very happy that Rackmaster decided to sell his .284 Model 70! Monashee

Haha...this thead makes me miss that damn gun........

A few random 284 thoughts..........

Mine is on a slimmed Ti action with a Wyatts box @ 2.975" Barrel is 21" Kreiger FW. The rifle weighs well under 6 lbs depending on the scope set up etc. Velocities top out comfortably in the 2935 fps range with various 139-140 gr bullets. FWIW.....I got well over that velocity but backed off because I just couldn't find a consensus of data that indicated that I should be getting any more than the range that I settled upon. My experience so far is that the 284 case is exceptionally strong and that it probably has the potential for equal velocities and greater case life than an improved case off of the .308 family. I have also owned a fair group of 7-08's and I'm of the mind that the average velocity difference is more or less maybe roughly 120-150 fps or so give or take a touch.

Who dat say who dat when I say who dat??..........

JimF

You had me till here....grin....

Yeah, just when you thought he knew what he was talking about.

Hey!!

I knew lotsa stuff about lotsa stuff.........once.

JimF

JimF- Glad to see you're still around!

Who dat got dat .284 Winchesta?

Approximate H2O capacities of the 7mm-08 and .284 with a 140 spitzer seated (measured with fired brass I have on hand):

7mm-08; 49 grains
.284: 61 grains
.280: 63 grains

According to the 1/4 rule, this means about a 6% velocity gain possible from the .284, in the same barrel length at the same pressure. If the 7mm-08 is capable of 2900 with a 140 (which is what I've found with those I've owned), then the .284 can get around 3075.

The 7mm-08 AI will be in between, but closer to the 7mm-08. I have only fooled with one, a rifle built but Kenny Jarrett. He sent along some of his handloads and they were SCARY, over 3200 with 140's. Kenny likes to step on the accelerator some.

Oddly enough, I have seen more feeding problems with 7-08 AI's than .284's, maybe because the .284's shoulder is 35 degrees, not 40 as in the AI. This should be that much difference, and maybe my experience was mere chance.

JB

Mule Deer,
How close would the 284 case necked up to 30 cal be in case capacity to the venerable '06? Hmmm....

I think he already answered that with the 284/280 comparison. It seems like a pretty interesting answer too.......

At one time recently I was considering a 30/350 RM (Cuz I have a 600 Magnum action rolling around on the floor)If that action were a std bolt face, I'd be thinkin' about a 30/284 myownself.

JimF

Jim,
I know, just thinkin on the keyboard!!

Hmm, now wouldn't a 30/284 make for a fun NULA!! Hmmm......
