I did that one year on accident but usually unload it at the end of muzzleloader season. The past 2 years have been easy as I've killed a buck, cleaned the gun the next day and put it back in the safe. Makes it easy. All you have to do is find a willing buck to participate.I've left mine loaded and used it the next year before and it's never hurt it. But anymore I always pull the breach out and unload it at the end of season.
Till buck down or end of rifle season unless have to swim out of woods...How long do you all leave your muzzleloader loaded??
