I recently purchased a renegade .54 barrel on the E trading blanket, pictures looked good and not over rated in the description. When it arrived it was uncleaned. after a cleaning it was pitted in the last six inches before the muzzle. I went to work with a stainless steel chore boy followed with JB paste. I figured if it didn't shoot i would make a smooth bore out of it. I shot it today using a .530 RB .015 patch lubed Bore Butter and 80 grains of 2f. Got a 4 inch group at 50 yards and all the patches were in good shape. Never know what woorks.
