Also has anyone had much experience with Cooper rifles, they look like nice guns for the money.

Dan Cooper gave money to the Obama campaign so he'll never get any of my money. Kimber is doing a Montana in the 280 Ackley for 2009......

Re: 280 Ackley vs 7mm Rem.

I don't have any 280 AI experience but have always thought it a interesting cartridge. I had the same question you have, I ended up going with the 7 Rem mag in a savage with a SSS 27" varmint contour barrel and am shooting an average fps with a 168 gr berger of 3208 using 74 grs retumbo. With fireforming loads it shot .355-.416 @ 100 haven't got to test fireformed load accuracey yet should be better. I didn't have much trouble with load developement just picked the powder the primer and bullet and loaded in .5 gr increments until one shot better than the others and didn't have high pressure signs. Hope this helps.

He did, during the 2008 election timeframe, and as a result of the backlash, is no longer associated with Cooper Firearms. Gotta remember this thread is three years old...

Re: 280 Ackley vs 7mm Rem.

I have owned both, still wished I had the ruger model 77 in the 7mag. But now I have a custom 280AI, 26" douglas barrel 1-9 twist. I have shot 162gr A-max, 140gr accubonds, 168gr berger and finally settled on the 160gr accubonds, with retumbo powder and 215M primers I am getting just over 3000fps and great accuracy. So I am very happy with it. It also has a jewell trigger that I installed and a boyds thumbhole stock. I would love to put one of those new leupold Mark 8 3.5-25 FFP scopes on it. Good luck

Re: 280 Ackley vs 7mm Rem.

Could I change my Rem 280 700 into a 280 Ackley or would I need a new barrel. Also, would it be worth it to do so?

It IS possible, but your going to give up some barrel length to do it.

You would have to have the barrel set back, so that it would allow the Ackley Reamer to cut out the standard 280 chamber. How much would be lost would be depending on the chamber you have now and how tight it actually is.

That said, for just a little more money, you could pick up a new barrel in the length, contour, and make you wanted, and have it installed and chamber to the AI version.

A few years ago, when I did my 25-06 AI I picked up a Broughton 4.1 Magnum Sporter 5C for something like $350, and it has a finished lenght of 28". With the added length and case capacity, I am pretty easily driving 120gr bullets to 3350fps with no issues. Doing the same with the 208, you could surely get some VERY respectable velocities with the slower burning powders.

I considered swapping the barrel out on my Ruger 77 to a .280 AI, but after speaking to Ruger about it I decided to leave it alone. It is the older tang safety with a 26" bull barrel on it and they said they only made around 2K of them in that particular combination. It still shoots bug hole groups out to 200yds with the Hornady 139 and 162gr bullets, and I am cleaning it up to possibly pass over to one of my nephews. Being as I have a 7 RM and an STW I just don't shoot it much if any anymore.
