I want to cast some bullets for the 300blk. I was going to get that 230 gr lee mold that they made for 300blk but have read all kinds of neg. stuff on it so I figured I'd use the 160 gr. 312 gas check mold I got awhile back for the 7.62x39 round.
I know you're supposed to slug the barrel for size but I hate doing that so, I prob wont. anyway my question is; should I leave the boolit as cast .312 +- or should I go ahead and size it down to .308? I sized some to check them out and that lee .308 die really puts that gas check on nice and tight, something the .314 die does not do very well.
I plan on TLubing them and loading them as light as the rifle will let me.
