79s didn't have much time this morning to post, so I just tried to stop you from wasting time with a plain base bullets, Get a copy of the NRA's cast bullet manual it has the info you'll need to flatten your curve. Lymans 311141 is a fn gc bullet for the 30-30 yet they shoot fine in my 30-06's more traditional 06 bullets were the 311291 and 311299 molds both rn gas checked. Hornady gas checks and good lube. Also get Lymans cast bullet hanbdbook. gnnoah also hit the bullseye on your need for a lyman "M" die for seating a cast bullet with out problems. MB
