Thread: Shotgun blackpowder Muzzle loading.....COMPLETE NEWBIE ADVICE PLEASE

Firstly welcome to the world of the true propellent, once you've gone black you'll never go back. You intend using a reprimed hull and stuffing it from the front, this may have several problems that need to be overcome, solid brass shells would be best as the crimp will prevent a wad correctly seating so with plastic hulls that would need trimming off.
Anyhow a standard charge of 2 f for a 12 g shotty would be 70 to 80 grains. On top of this goes an overpowder wad it needs to be about 1/2 an inch thick and cut from a compressible material, I use pinex acoustic tile. You will need a wad cutter for this. This is rammed down hard onto the powder charge followed by a cardboard wad, the shot charge is then poured in and two over shot cardboard wads lightly forced down to hold the shot tight. Personally I NEVER cap a piece during loading you will be loading on a live primer relying only on a safety catch and thats a risk I would not take. Why not load bp cartridges to see if you are really hooked, and then look at getting a proper muzzle stuffer.
