Hi there guys and gals! Being relatively new to muzzleloaders I have a question that may seem dumb and may also have been addressed/answered before BUT I would appreciate knowing HOW LONG can a BP pistol be left fully loaded when using Pyrodex RS BP substitute?? I have a new, never fired LeMat and a new, never fired Howdau, and a new, never fired Colt Walker and I was wondering if I could load them and then leave them loaded for a few weeks before firing and then cleaning?? I apologize IF this is a stupid/dumb thing to ask but I don't want to damage these pistols because they were relatively expensive AND I was thinking about carrying one around my new wooded property for protection. THANKS for the assist!!
