Nice shooting Semi. On the 125yd target: My guess, the round ball being round, needs relatively little rotation to stabalize on departure, enough to overcome the turbulance at the muzzle, but being of very low BC, succumbs rapidly to destabalization at a break point in speed as determined by charge. Makes me wonder if you bumped that charge by 5 grains, if it might not be spot on at 125? More shooting necessary?
