80gr 2F Goex, Not bad bad, but not good IMO.
90gr with .015" patch and a .018 patch used as a buffer to protect the main patch. I should'a stopped after shot 4 as the bore was getting tight.
Left: .015" patch with 80gr Goex 2f. Right: .015" patch with 90gr Goex and protected with a buffer patch. A big improvement and once i buy some .54cal wads, the patches should look pristine.
