I know to many reloading ?s will get this moved so I will try to stay on topic.
So when casting bullets for your "SIGMA", do you purchase a lead alloy designed for bullet casting?
I would imagine using misc lead to melt down would lead up the "SIGMA" even worse.
I am just getting into reloading. In fact loaded the first 100 rds last night for my "SIGMA".
We used purchased bullets but were discussing casting.
I would love to pick your brain further, you know to make sure I take care of my "SIGMA"!!
