A guy at the club passed on and had a pile of lead ingots that he labeled "631". Does this designation mean anything to you all? He had some labeled LT which I assume is Linotype, and WW, which is wheel weights, but I'm scratching my head on the 631.
This raises another question of how do you label your alloys? Personally, I have Lyman #2 that I make from 10# of wheel weights and 1# of 50:50 Pb-Sn bar, what I call "3% Sn" that is range lead plus 3% tin, and then pure led that I label Pb and use to make the 3% Sn. Most of my casting is for pistol, so the simple 3% Sn alloy works fine. I save the wheel weights, Lyman #2, and any linotype for gas checked rifle bullets. FYI, I use either Lyman Alox, or a homemade lube that is 5 parts beeswax, 1 part moly disulphide grease, 1 part ATF. I only use Alox when I run out of beeswax...
