I need to slug my barrels and have a few questions:
1. Do you use a round ball or an actual cast bullet for the gun? I ask because I don’t have round balls in the various calibers I need to slug. I do have a round ball mold for my River Old Army... but I need to slug a .38 Spl, .45 ACP and a .45-70. I have SPFB molds for each and thought I might get away with using those.
2. Do you use pure lead or the alloy that you are currently casting in? My instincts say that you want pure lead because it will be easier to drive through the barrel and leave good rifling marks.
3. Any other suggestions?
