i have a newer 1894 44 mag a few years old with ballard rifling. i cant seem to break 4 moa. ive tried 3 different mid weights 240-260gr and 300gr wfn, tried them from expanding soft to heat treated ww hard, been powdercoating them and trying sizes from .431 to .433. people said size to the throat but they dont have throats. the bore slugs .431 at the front and .432 in the beginning. and im testing accuracy with a leupold vx3 4.5-14 mounted with wheeler fat wrench, so it should be a gun problem and not an aiming problem. anyone been here before?
