relative to flintlocks, as long as the frizzen is open, the lock cannot spark. As Tiriaq commented, I suspect my reduced bang experience with a percussion gun was more likely a result of residual oil that condensation. Also I would be very hesitant about keeping a loaded muzzle loader in my house or cabin because I expected to use it again the next day. Circumstances change and the charge remains and is forgotten about etc. Some years ago, a gunsmith friend managed to shoot the wall of his shop with the loaded barrel of a double shotgun. Customer wanted the breach plug or nipple removed (can't remember) and was asked "is the gun loaded ---- definitely not" He then checked one barrel with a ramrod and it was definitely empty and he did not check the other barrel. Needed heat on the breach of the other barrel and the gun was in his vice. On about the fourth cycle of heating and cooling ----Kablam
