For starters I installed a Davis double set trigger on my Renegade .54 flinter with GM 1:70 RB barrel. Then dissassembled the lock on my Firestorm .50 flinter and painstakingly de-burred and honed all of the surfaces of the tumbler and sear with India and Arkansas stones to get them butter smooth. That gun had a horrendous trigger pull from the cast surface on those parts. Now it's SWEET! No, I didnt remove any metal, just polished them smooth. Then I ran a patch dampened with ballistol down the bores of some of the ML's I haven't shot for some time to make sure they're still protected. Now if it ever stops raining I can get back to shootin'.....BPS
