This is my first year with a muzzleloader, and after getting my gun sighted in @ 100 yards, this issue has been top of mind. I've pretty much heard all the possible solutions here (I think) and it seems that the best thing to do is just fire it off, clean it and start with a fresh load for the next hunt. I'm only going to be hunting w/ my muzzleloader this coming up weekend and the following weekend, so I won't be wasting a lot of powder, etc. I usually hunt from a treestand...if I do any hunting on the ground, I might just pull the primer out in between hunts on the same day, but otherwise, I'll be firing it off.
