I have a Saeco #382 4 cavity .357 mold. It cast beautiful bullets in cavities number 2,3,and 4. Cavity (Farest from handles) 1 doesn't quit fill the base out. I am new to a 4 cavity mold. Have several 2 cavity molds. I can raise the lead temp to frosting and #1 fills out great. What am I doing wrong? Add Tin? I am using range lead mixed with wheel weights.
Long time caster but feel like a newbie. Help!!!
Thanks,
TF
