My plumber buddy dropped off probably 50-60 pounds of lead pipe. I've only casted WW and am not sure of mixtures ill need for this lead. Ill be shooting 9mm (around 1000-1100fps for the 124gr and around 800 for the 147gr) and lee 55gr 223 going around 2400-2500 fps, Ill be powder coating these, and probably gas checking the 223. Any help for a mixture for my 10lb pot, i dont mind making a different mixture but the 2 as they will be going at way different speeds. thanks
