Taint no 7 mag that's for sure.
I personally hate trimming brass, and it sure is a sexy looking cartridge.

Fantastic way of putting it, as long as it feeds every bit as good as standard rounds then I get it. What I dislike seeing is those trying to push it into a pasture it maybe shouldn't be pushed into. And for what........another 100 fps or so whoopy... wink

You know I think the need for speed thing has been around for a while and you can see it being done with most any caliber. If we start being pragmatic around here and using good ole sound logic and common sense then we aren't going to have much to talk about!

I'm far from any expert, but from every article I've ever read the .280 AI is supposed to be one of the most benificial from being Improved. Close to 200fps gain, improved brass life, and it's damn sexy...

NO expertise here for certain! When I bought my 280 AI is was simply because I wanted something different than normal. I had spent all my adult life hunting with either a .270 or .308 and both did a damn fine job, but I wanted something else.

I sure as hell wasn't about to go the full custom route, so I went with a Cooper despite not being fond of their actions. Boy am I glad I did. The damn thing is incredible. Here is exactly what I know, factory 280 ammo (140 FP) runs about 2850 in my gun. 140 Berger or Nosler Accubonds with 58.5 IMR 4831 lope along at 3050 and shoot one bug hole.

150 Nosler BT with 58.0 of the same 4831 also runs along about 3060 with a Fed 215 primer and OMG does it shoot! And the Nosler 160 AB with 56.0 of the 4831 is just shy of 3000.

I have no idea how much faster they could go and I have no intention of finding out. The damn thing shoots remarkable too me and ultimately that's all that really matters.

Funny thing about all of this, I have killed 6 critters with the 280 AI and upon inspection their death closely resembles that of the many more critters I have killed with the .270 or .308.

cal74-I wasnt't overly clear about what I said. I meant to say that if you push the AI it may well get within 100 fps of the 7 RM. I wasn't meaning to comment about how much one gets over a regular 280. Make sense?

And from what I've seen the AI users are running them awfully darn hard to get within 100 fps, I expect with time people will back off a bit and begin to see 100-125 or so over the regular 280 especially if they're to get any sort of case life at all. Most of the 280AI users I've been around are probably seeing the primer pockets get loose after one or two firing and most likely can't keep a primer in the pocket around 5 or so reloads. And that to me is what I'd not be comfy with.

Just my way.

I got an easy 3050 with the 162 Amax out of my 26" .280AI.

Never wore out a case either.

If you stick to book max loads the .280AI is every bit as fast as a 7RM.

It is my favorite rifle. I shoot 140gr ttsx at 3300 fps and they shoot into the .2's and .3's which is awesome. Oh, it is a Kimber 84L as well. It will be the last to leave my hands. I know it's not a 7 mag but I don't care for the extra recoil. That's why I sent the 300 WBY down the road.

Great round, but just too much for the killing I do. If my .260 and 6.5 Swede will kill Elk at 400 and 500 yards, I don't see a need to shoot much further than that, I would rather get closer. My 2cents.


Enough already, just shoot it!

Yeah if you (a) put a 26" barrel on the AI;and (b) dumb down the 7 Rem mag to lower pressures and use a 24"..

C'mon Ken.... grin

I have 40 Federal cases that started life as a plain jane old 280. 28 of those 40 are on their 6th trip around. The other 12, 5x's.

No trimming to date, no loose pockets - lucky I guess wink

Good Q Splatt so I looked em up, using apples to apples. Nozler Part for both.

270/150 has a BC of .465 and a SD of.279

7/160 has a BC of .475 and a SD of .283

Sexy is a big critter on the turf like a oryx that your're about to bounce...grin

I didn't dumb down the 7RM to lower pressure, SAAMI did.

I didn't maximize the efficiency of the .280AI, SAAMI did.

SAAMI matters to the people who print loading manuals. It matters so much to them that they simply will not list loads which exceed the SAAMI MAP.

Im hoping so!
Maybe, just maybe, one is tough enough to hold a 140 ttsx.
If all goes well. Will i be the first to kill an oryx with a 280ai?
