I have a 8MM Hakim simi auto and I have been wondering if I could shoot cast out of it? I shoot cast in my M1 Garand but the gas system is different on the Hakim it is a direct gas system like the M16 and the MAS 49/56 no piston. The gas port is almost in the middle of the barrel and it has a control valve. I have a 8MM mould but do not have a Mauser ect.
