READ everything on muzzle loading you can get your hand's on, and make sure you have somebody that know's what they are doing guide you through the steps and make sure your loads are suitable for what ever you are shooting, it can be very dangerous if you don't know what you are doing!!!
you have to use the right powder for the right cal, for instance if you were to purchase smokless pistol powder and fire it in a muzzle loader you are more than likly going to blow your face off, there are alot of dismembered and dead people out there that just did not do the math, muzzle loading is a great shooting sport, just take the time to leard, you don't get any second chances and I'm sorry dos'nt fix anything!!! Good luck, and enjoy!
If you run your just going to die tired!!!
