I cast some Lee TL430-240-SWC bullets and some Lee 429-240-2R bullets recently. The bullets were cast from the same pot of alloy on the same day. I powder coated and sized them tonight, and decided to weigh a few of them. Both bullets should weigh near 240 grains. The TL430-240 SWC's came in at 239 grains. The 429-240-2R's came in at 259 grains. Could Lee have marked the mold wrong? Or perhaps cut the mold too deep? I'm stumped, any thoughts?
