GoForBroke, I wanted the same thing you did with my .243 AI. What I did is I found the 87 Vmax and stuck it over some H414. It has one of the highest, if not the highest, B.C of a bullet under 90gr., at .400, and it is extremely explosive. You should have seen the rockchuck I hit at 470 yards on Saturday. No joke, it blew that thing in half and the top half landed 6 feet up the rim and we couldn't find the bottom half. These are going 3340 fps at 20 feet from the muzzle. These also do a good job at 550+ yards, still empties them out there.
