I have both the 6 cavity TL452-230-TC and the 2 cavity 452-230-TC (same bullet/single lube-groove version), both new molds. The same pot of lead casts the tumble-lube version at 238 grains, and the single lube-groove version at 228 grains.
For those who use these molds, is it normal for the TL version to be 8 grains over the 230 grain spec?
