Re: High BC .224 cal. bullets
A number of people in the HP community seem to have had problems w/ A-Max's pushed too hard -- they sometimes don't make it to the target. Guess it'd be one thing when you are hunting and it just botches a shot, but in score shooting its 10pts and a possible X down the drain. If the manufacturer lists a max velocity for a given twist, I'd say it might be wise to take it seriously. Obviously, the bore condition has some impact on this as the bullet gets on its way, so some people can push things more than others. YMMV.
