Remember to clean your muzzle loader every year!
My buddy (middle) has a nice scope tattoo on his eye/nose from double loading his muzzle loader.
He forgot to clean it the year before and went to sight it in for the upcoming season
and already had a charge from the year before!!![:@]
This is why you make a witness mark on your ramrod - so you know instantly if there's something in the breech which should not be there when you load it......
