280 improved ackley

With what bullet weight? It doesn't matter how much taper a case has, or what degree of shoulder it sports, it basically comes down to case capacity. A 280 AI does NOT have more case capacity then a 257 Wby or a 7 Rem Mag, and therefore will not outperform those calibers with all other variable sbeing equal. It does have more case capacity then a 270 Win, and therefore, all else being equal, will outperform that caliber. There are a lot of other things that weigh into this issue though, bullet weight and design, barrel length, fast or slow barrel, etc. FWIW - dan

There seems to be a lot of interest in this chambering. We sell more Cooper 52's in this than any other. Almost as many as all other '06 based chamberings put together. A lot of guys are using it for sheep. Almost the performance of a 7 mag with the smaller, lighter cartridges and rifle.
The best .280 AI is a 7WSM or 7RM
and I was thinking of putting together another one...you just dashed my hopes...hope you're happy...:-(
...uh....where is the infamous 280_Ackley?.....he should be weighing in on this one.....
mine is a rem blued synthetic mountain rifle. not quite as fast as a rem 7 but close with a little less recoil. it has a kdf brake too maybe why the recoil seems better. lighter and less recoil whats not to like. prefers 140 ab or bt and a whole case full of rel 22. cronys over 3200. excelent case life but the 280ai marked cases are a little pricey.

Uh, I can put five 280 AI cases in my Model 70's magazine. How many of the above mentioned cartridges are you stuffing in yours?

3+1...
Why do you need 5 cartridges to kill an animal with your 280AI?

They're not really too bad. We carry the Noslers and its 50 to a box and they are sized and weight sorted already. $67.99 A lot of guys are getting them and they don't have to wrry about the data stamps and headstamps not matching for overseas travel.
A .257 Wby has virtually no recoil (to me) and with 100gr TSX at 3500fps it makes a fine long range round.
A .270 has very little recoil, and I'd love to try one with 110gr TSX at 3500fps. That seems, on paper at least, to offer one of the best combos of bullet diameter, velocity, flat trajectory and powder charge out there.
The 7mm RM is a step up from the .280 AI.
In my 24" 280 Ackley, 120 grainers clock 3370 fps, 140 grainers go high 31's, and 150 grainers clock 3050. It won't match a 7mag. But if a 150 grain 7mm TSX at 3050 isn't enough, the answer isn't more speed, it's a whole lot more bullet diameter and bullet weight.
It's a great cartridge, perhaps even the slightest bit better than a standard 280!

I know a guy who shoots a 280 AI. Swears up and down by it. Personally I would never shoot an AI unless it was single shot or a non-staggered mag.
Huh?

Too bad they wouldn't chamber a SPS SS or the CDL SF in .280 (that would be sweet
Because Remington never makes any sense with deciding which calibers go in which models. Seems like they always chamber the coolest models in plain jane calibers only.
