I just got my 38-55 Lyman mold, the one with the gas check that is listed to throw a 264 grain bullet. Cast up a bunch today and they weighed in at 287 grains. Rather surprised at the difference. 50/50 WW/lead alloy. Same stuff throws a 258 grain bullet out of my Lee 250 grain mold so it is generally a heavier bullet than the #2 standard but this was a surprise. Had another mold once that was supposed to throw out at 220 grains and the bullets came out at 240+. Others see this large a difference?
