what am i going to gain by going from a 7-08 to a 280 AI in a 15" barrel? I know several of you have both in similar guns. Is there enough difference for a rechamber if you are going to keep your shots under 400 yards. currently shooting a 140 vld berger at 2614 fps.
Guessing 200-250 fps faster
My 280AI has a 17" barrel and is running 140AB's (factory Ammo) at 2961. Even if I subtracted 35 feet per second times two for a 2 " shorter barrel, it would be running about 2890 fps.
That is significant, and I would want a Berger to be doing at least 2000 fps impact velocity.
