I shoot a Pro Hunter 50 cal. I use bore butter to swab/clean
between shots...I use 209 shotgun primers...200 grn Shockwaves..3-50 grn pyrodex pellets...Gun shoots 1"-1.5" groups100 yds. It is sighted-in 2.5" high @100 yds. That gives a 2"-2.5" group at 200, 3" low.....That has accounted for numerous critters. The gun is 5 years old and was cleaned in July for the first time with a wire brush....It shot to normal point if impact last weekend with its normal load(after 2 fouling shots)....YMMV
