Vearl,
I've been casting for 19 years, I own 9 of your molds and love all but one! About 15 years ago I bought (form you) a 30 cal. GOP, 310 dia. mold. But I never could get the bullets to shoot so I put the mold on the shelf. This winter I took the mold down and started messing with it again, I feel I've followed your instruction fairly carefuly but I am wondering if I may be sizing the projectiles down to far (308 dia.)? And yes I do use your lube.
As a side note I've taken 1 moose, 1 bear, 8 elk, 12 deer, 3 antelope and 1 house cat with various 45 cal. LBT bullets, most were 1 shot kills.
