Thats all well and good and needs doing - not gonna be enough tho with a 32 + small diameter nipple drum + small ignition channel + homemade powder == you can easy get bridging across the nipple channel that puts you out of action --- a few smart whacks with the palm of an open hand in the breech area will sort it - been there done this a trime or two ..........................but that dont count I guess
