Well I recklessly got some lead off this board without even knowing what it would be good for. However I usually just go by the honesty of the members on this board and it hasn't let me down yet so I have little concern. However I got about 100lbs of the following lead. I do not know lead hardness differences or what different metals do to the lead so I'm kinda lost in figuring it out myself.
Alloy 95% lead 5% antimony cast from Redneck Gold and Cast Boolits molds
