Tactical comp rifle question? Why not a 284 case?

[XTR]

I'm pondering my next build and I've had plans for a 7-08, but I got to thinking... Why not do a short action .284Win? That got me to wondering why the comp guys aren't running SA 6.5-284s instead of the 260Rem?

I've got no experience with either so let me know if my perceptions/assumptions are wrong here.

I know that to load to it's full potential a 284 should be in a long action, you can't seat the bullets long, but I think guys running the 162Amax in a 708 or the 140s in a 260 are bumping up against that problem with mag length. Even seated deeper I'd think that you'd certainly be able to get better MV from these pills loaded in a 284 case even if you are sacrificing some capacity. Yea, I get that it's not running at it's full capability but it would be easy to exceed the capability of the competitor 308 based cases.

You wouldn't have to load to near max to get good MVs, and if you're pushing the same pills at only a couple of hundred FPS higher speeds then recoil should be a wash.

Stating the obvious, you don't have to load it to max.

Is there a mag capacity or feed issue from mags with the 284 case?

Am I missing something?


I Lapua makes brass for the 6.5/284, and I know WW does.

The 6.5x284 is a tight fit in a SA. Plus, I've heard of guys losing barrels at 700-1000 rounds due to burnt up barrels. 260 and 6.5 Creedmore are at least 3-5 times that barrel life.

And...It's the Indian not the arrow.

I get that a hot loaded 6.5 eats barrels, but you don't have to load that hot, and I get the Indian part too, but there is a reason that the 308 lost favor, the Indians are looking for any advantage that they can get, and if the skills are close to even then the arrow can make a difference.

I have been shotting my 260 for about 18 months now and have 3500 rounds on it, still shoots awesome. I think the 6.5 creedmore will do the same and be similar performance. Yes I can only load my cases with the 142's OAL 2.820 and safely run through a non modified AI mag. I'm running in the neighborhood of 2775 give or take. I just build a 243 to see if I like it, it shoots really nice, soft recoil, very accurate and I'm only pushing the 115's just shy of 3000fps hoping to extend the barrel life, we'll see. It's all a trade off, barrel life for speed, it just depends on your goal and your turn around time from your gunsmith on rebarrels. Oh, and I do have a .284 I built fir a lightweight carry gun, its a real humper, I built it in a short action to minimize weight and went 7mm for hunting bullet selection. I probably didn't tell youanything youdidn't already know, just relaying my experience. I also really depends on what distance you shoot and conditions to decide how much speed you really need nad at what price, we are all looking for that magic combination of speed, accuracy, BC and barrel life, let me know what you come up with, I haven't found one yet!

Re: Tactical comp rifle question? Why not a 284 case?

if i were going to squeeze a 284 into a short action, i think i'd lean toward the 284 shehane with 162's. personally, i'll stick with the straight 284 in a long action with 175 smks though.

6.5-284 is going to be quite a bit rougher on barrels compared to the 7mm.

Re: Tactical comp rifle question? Why not a 284 case?

Long Action 284 w/ a 27" barrel is getting my 162 AMax up to 2980 with no pressure signs. Barrel takes 22-25 rounds to get hot and Im easily hitting 1/2 MOA targets out to 1100 yards.

It would be a long overall package to haul around in a match but it would more then do the job.

Yea, that's what I'm thinking.

I'm currently in the middle of re-configuring/building most of my bolt guns.

I've currently got a 308 in an McM A5 that I put a 30" Krieger on to shoot in F-TR, but I've gotten the parts in to build a dedicated F-TR rifle on a Defiance action, so that rifle will get rebuilt into something else soon.

I've also got a 308 Remington Varmint in a B&C A2 that I use for deer hunting but I find it too heavy and long. I have the original VLS stock lying about so I've picked up a trued stainless R700 action and a fluted #5 in .284 from the Rock Creek group buy that I want to make into a 7-08 hunting rifle.

Then I can have my smith chop the barrel off of the RV at 22" to make it less unwieldy (I'll have the 30" TR rifle) It shoots .75s with hunting bullets so I'm not going to re-barrel it.

After that I think I'm going to do what you did with the 308 that I'm currently shooting in F-TR and make it into a 284Win for tactical comps or when I just want something more than my 708. Of course then I'll have to figure out if I really need my 7mmRM BDL hunting rifle, and if not then what does it need to turn into. (this is a sickness, it really is)

XTR what did you end up building?
