Having loaded and shot both a lot.
Pressure for pressure, the AI won't get within 200 fps of the 7 rem mag.
I have been searching for a smith to do my work on my rifle, in my searching i came across what it looks like a good deal, Cooper makes a couple of 280 ackley rifles, one I believe a stainless rifle, set in a B & C Medalist stock, bedded for around MSRP $1600 or so, they also guarantee a 1/2 inch group @ 100yrds. sounds like a pretty good deal, I'll just have to see how long a waiting there is for the rifle.
Also has anyone had much experience with Cooper rifles, they look like nice guns for the money.
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?
