First off..........you do it in an area where you don't inhale "too many" lead fumes and secondly........you scrounge lead so you end up with basically free lead. Your equipment can be a ball mold or mould if you prefer, an old spoon to dip with, and old hammer handle and a camp stove with an old discarded sauce pan. .....Macon DueTime is a precious commodity. I'd rather spend time shooting than inhaling lead fumes. Read a post here yesterday that said a certain RB could be bought for 14 cents each. If you made your own the lead cost was 8 cents. Amortize the cost of the casting equipment & you are saving nothing for the first few thousand rounds. Hardly worth it, IMHO. I understand that some enjoy that part of our passtime & am not criticizing those that do. It's just not for me.
