today i wanted to shoot my muzzleloader and make sure it was sighted in. I loaded it and put a primer in, sat down, and when i went to pull the hammer back it wouldn't click and stay at the pulled back positition. but when i opened the gun up, it would stay back. Neither my dad or i can figure out what the deal is:smiley_confused_vra:smiley_chinrub:. Anyone have a clue? Thanks
