lots of accidents happen. Bad customer service by the muzzleloader uneducated is a big problem in chain stores today with the employee selling what he was told to sell the customer without any real knowledge behind it.
Plenty of accidents with muzzle loaders from forgetting to seat the ball, forgetting to ram the ball on the powder, double loading and having the second ball push up off the charge due to the air pressure built up while loading on top of that first charge ( ever load a tight fitting wad into a muzzy shotgun and have that air pressure shoot the ramrod outta your hand? boy what an experience!) .
Foolish to make videos like this? No.
Its educational and shows you that if you want to be stupid and not learn about the sport first, this is whats going to happen when/if you foul up.
Believe it or not, some guys shoot smokeless in newer muzzies that are NOT designed for it but do so because they used a reduced smokeless load that generates BP pressures. Stupid? Yup!
Poke the Pitbull to much and you are going to get bit sooner or later.
