Your guns will be clean and rust free and will have no lead rings on the cylinder faces.
A good site to learn the basics of loading BP cartridges.
It may not be for every one but to load a box to use at the end of your shooting sessions isn't difficult. SJ 40
But do you think if I ran 50 or so rounds of factory FMJ through it and wiped it right after it would come off? Would I needa apply any solvent while it's still hot? Like at the bench at the range?
