My 45 Bullseye gun never leads up but that's the only one. I only shoot lead in pistols except for my EDC 9mm ( that's because I simply don't want to reload for it). My 40's, and some 38's, lead up and after about 300 rounds and I have to clean them out. I wrap copper chore boy (NOT the copper coated steel chore boy) around a mob and, after letting some solvent sit for a bit while I clean the rest of the pistol, start pushing it through. I can clean all the lead out in less than one minute. Far less effort than trying to clean copper out of my rifles. Now I'm a bit lucky as I cast my own bullets and can size them to match the barrel. Since I got all my lead free at a local range I can reload any pistol caliber for just under $4 a 100. If I had to buy powder and primer at today's prices it would probably be just over $4 a 100. That's why I shoot lead.
