6.5x284 & 280ai comparison

[bassassassin104]

Probably a silly question, but I have to ask anyway. You building the 6.5x284 in a long action?

 

[FEENIX]

Bump that 180 to 2850.

LOL, bump the 6.5x284 with 156 to 3000 FPS ...

Hunting and shooting with my 6.5x284 along side a few buddies with the 280AI, the differences are difficult to discern. My 6.5x284 at 2975-3000FPS with the 156 EOL's IMO, more then evens up the ballistic comparison delivering 1000FPE to 1100-1200 yards at +1700FPS (4500fr elevation).

There are several 180gr bullets in 7mm to choose from…there is only one 156eol
Edited, finished reading thread, if u have that many components choice is clear 6.5

Yes, Long action. Ordering a Defiance AnTi-X LA

Max range is accordingly at this point. I would love to be able to have a rifle capable out to the ~1000yrds with proper energy/velocity to expand the bullet and I always had in my head I need 1000 ft/lbs of energy but idk about that.

So that's why I'm trying to compile data and compare the 156gr out of the 6.5x284 vs the 280ai with "xx" bullet. Which cartridge will have better velocity and more energy downrange.

It's just slow and time consuming to research the energy/velocity data I'm looking for. So I didn't know if there was something to make that process easier.

Best option to have enough energy at 1000 is going to be an RUM or Nosler based round

Perhaps, but the OP...

I know I don't want a magnum cartridge.

He already chose the 6.5 but since we're LOL. Another member on this forum pushes his 280AI a little harder and provided his data...Let's see a 6.5 shoot a 195 grain bullet. Even at a 280AI at a methodical 2750 can do some work at 1000 yards. The ****ing contest is very close no matter the outcome, but at the end of the day I'm shooting 6.5's at deer and 7mm and 30's at elk. That's just my preference. You and the OP like the 6.5's, so that's cool. Go kill em.

"I have had good results so far shooting heavy bullets in my 280AI. I have found IMR 7828SSC, H1000 and RL 23 all work well with 180gn Bergers and 195 Bergers.

A few loads I have worked up so far:"

180 Berger Hyb

2.821" to ogive (~0.020" off)
2923 fps, SD 3.4

CCI BR-2
2.814" to ogive (~0.020" off)

0.38" x 3 shots

180 Hornady ELDM
59.0gn H1000
Fed 210M
(~0.020" off)
2746 fps, SD 12.8
0.34" x 4 shots

195 Berger EH

I plan on running with either a side port muzzle break or a suppressor.
With the added bearing surface of the 7mm bullet, would there be much of a difference in recoil? Not that that's a deal breaker, just curious.

I think I'm leaning 6.5x284 simply because I already have components for reloading. If I go the 280 route, I'll need brass and dies. But should I let that be a deciding factor cause I'd have time to accumulate those while rifle is being built.

I'm kinda in the same boat. Just my opinion on paper, and going by other's actual field results, I'd give the edge to 7mm's especially for elk. But I have all the components for my 260 AI that's being built so I'll keep it. I have other actions that I can build a standard 280 Rem, 280 AI, or even a 7mm RM on.

Chill out, you misconstrued my point. Nowhere did I say I prefer the 6.5x.284 over the .280 AI as per my original response to the OP ...

Why compare two different caliber/chambering? The .280 AI will give you more energy downrange, esp. with the right bullet. However, the156 EOL when propelled accordingly is no slouch. What is your max range? Yes, you can calculate and compare KEs between the two.

If I was going to shoot 140gr bullets, I'd absolutely pick the 6.5x284.

I wouldn't, in a long action I'd pick the straight .284 Win

 

[FEENIX]

Yes, Long action. Ordering a Defiance AnTi-X LA

That would do it. Good luck!

I never did mention but I do also have a Christensen ELR 300wm. That's why I didn't want to choose a magnum here. So maybe that little bit of info will help cool down the "if you really want energy" discussions.

I was just going to post that a 6.5x284 would be a great choice for most of your game you picked. Probably fits in better since you have elk covered with your 300 WM.

Dead is dead whether with a bullet or bowling ball dropped out of a 747. The reality is which will you shoot better because bullet placement makes all the difference. A lot of male egos on here will show billfold target groups at 800 or 1,000 yards shot from a bench or prone but...single digit % hunters can produce that in the field. Beware the man with one gun! Karamojo Bell killed over a thousand elephants most with the 7x57Mauser/.275Rigby or .256Manlicher . Paper or computer screen data is impressive but bullets like the much copied Barnes X penetrate to vitals for DRT performance. When culling for the village in Africa my favorite was a 7x57 Rem Mt rifle with 160gr Barnes X. It took mountain Reedbuck/Impala/Topi/ Kongoni/even one Cape Buff at 142 paces. Build fewer rifles and burn more powder to be an assassin ... Seals/Rangers/DeltaForce/GreenBerets don't shot .280AIs...they shoot a lot of .308s!
