I wouldn't do either but I would build a 250Ackley Improved. More room to seat your bullets out, just as good of velocity, and a real killer of medium game. The 90, 100, and 110AccuBond are all great bullets. 3250fps w/the 85gr TTSX, I shoot the old 90gr X but the 110gr AB seems to be tailor made for the 250AI.powdr
