Rotometal lead.

[Gunlaker]

I used to buy 99.99% lead from a local place. They also sell ingots with 2% antimony. I don't know if I got one of the 2% ingots mixed in (they are 60lb ingots and I was buying them 5 or 6 at a time), but I had a bunch of bullets that were, if I remember correctly, about 8 grains light. I could tell as soon as I started casting, the melt temp was just a bit lower, and it was really hard to get perfect bases as the sprue would tear just a little. The bullets did shoot very well though.

I heard good things about Rotometals so switched a while back. So far I haven't had any significant changes in weight from batch to batch. I like to buy 150 lbs at a time so I have as little variance as I can get. I will be on the lookout for it though.
