Too windy + questionable weather forecast today -> me casting, sizing, and lubing a small pile of LBT ~470gr. FP (truncated cone), but plain base* CB's for my .45-70 Marlin #336. Those CB's are scary accurate @ 100 yd. too, but are deadly at both ends with heavy loads!
*Originally 1 cavity was cut with a gas check shank, but after a few rounds of 1,300 - 1,350fps in such a light rifle, I decided a GC wasn't necessary and sent the mold back to Veral Smith to remove that feature. He did and both cavities drop equally accurate CB's.
