I finally got around to unboxing the Lee TL356-124-TC mold that I bought awhile back for casting 9mm bullets for my 9mm handguns and for my P229 in .357SIG.

The alloy I'm using is basically a mix of regular wheel weights, stick on wheel weights, and a bit of #9 shot that I had sitting around from previous use in a SCUBA soft weight belt pouch. I also tossed in about 4" of solder in the 20# Lee bottom pour pot. Yeah, I know -- not exactly a repeatable alloy.
Supposedly, the mold should be throwing bullets at 124 grains. My scale only goes up to 1000 grains, so I took 7 of them in order to average them. 918 grains total, which equals an average of 131.14 grains.
Is this a reasonable value? When they are rating a mold at some particular weight, what alloy are they using? I would have thought that whatever else that might have been in my alloy would have make it lighter than pure lead.
