Would you say that a 7-08AI is essentially a 280 Rem "short"? I've been tempted to punch mine.
I own a 284 win Model 70 S/A which is a ballistic twin to the 280 rem, and there is a slight edge to those cartridges over the wife's 7-08ai. I run the wife's at the high end of the std 7-08 plus maybe 50 fps and get no pressure signs, great brass life, just a little more "oomph" over the standard 7-08 which isn't a shabby round at all - especially with 120-140 gr bullets.
Not sure I would go through all the fire forming work again if I had to do it all over, but the overall outcome is a very nice rifle. A 120 gr bullet at 3150-3200 fps and a 140 gr at 2950 fps are safe loads in this gun. If one really wanted to push it you could maybe get another 50 fps over these velocities - I am comfortable with where this one is operating and am confident no limits are being approached.
Through a convoluted series of deals (mostly from the 'fire) over several years, the wife's 7-08ai ended up being essentially an Alaskan Ti stock and barrel (24") with the standard Rem 700 (non-Ti) action. It tips the scales at 7-3 scoped. As far as the barrel question, I don't like the pencil barrels either, but personally, 22-24" would be my preferred, with of course 23" being perfect. But trust me, nothing is getting changed on this gun. The wife loves it and it is staying just the way it is.
