STEP AWAY FROM THE RIFLE.
You have some reading to do. I am assuming that you have a traditional style side hammer caplock rifle. HERE IS THE OWNER'S MANUAL.
Print it and read it- ALL of it.
Two general rules for muzzleloaders-
First, NEVER shoot anything but real actual true marked that way on the can BLACK powder- or a product made as a black powder substitute, such as Pyrodex. Yes, pellets are fine.
Second- NEVER attempt to fire a muzzleloader when the bullet is not all the way down the barrel on top of the powder charge. Having a gap between powder and ball will destroy rifle, and not make you look too pretty, either.
Read the manual, then come back to us with questions.
