With the double barreled smokepole, I find I can shoot a quick left and right, or shoot the right, then reload it and shoot again- centre hits at 50yards. If I load and shoot only the left in the same manner, I get centre hits at 50yards, no change. Increasing the charge 10gr. makes it shoot parallel - whether shot quickly or slowly.

Perhaps this is only 'normal' for a muzzleloading double rifle shooting round balls? Perhaps it's only normal for my ML rifle? 'm more than happy it seems this 'stable'.I
