Wow...I don't do any of what you guys are doing...I simply load roundballs with grease over them or conicals with grease on them and no grease over the chamber mouths...never had any problems. Cleaning has always been with hot, soapy water and oiled with plain old Hoppes gun oil or lately Rem Oil, whether it's a BP rifle, pistol, or revolver and all have stayed rust free for over 30 years. I guess I've been doing it wrong all these years. :banghead:
