Hi everyone so I have a question and it's bit of silly one but I'm more currious if it could be done ,and if so done safely .So my question is I have a 50bmg barrel and was currious if I could use it to make a smokeless muzzleloader that could shoot 50bmg bullets the big heavy bullets 660grain ?would it be possible? also a breech plug ,if the idea is possible I was thinking something like the tank style 3 groove intrupted locking threads
