I'm using Tula primers, WSF powder 5.8 grns, friendswood 230 grn lead round nose at .452 to plink. I don't have a chrono but it is the starting load. I looked at the barrel after maybe 75 rounds and to me it looks like a lot of swiped lead between the grooves. I used hoppes elite for about 6 passes and regular hoppes for about 15 passes still looks fouled up! Any help would be appreciated.
