I am putting this down as a goal to reach toward in the near future. I recently purchased a .308 cal. bullet mold with gas check. Also purchased a .308 sizer die. I want to use this in developing a 300 Weatherby Mag. load, that far exceeds factory specs. The die is for a 165 grain bullet. I plan on quenching the hot bullet in water to harden it, and will be using, what I call, super-lube.
After molding the first batch, I will let you know what the real bullet weight turned out to be.
Factory specs are: 3450 f.p.s. (4360 f.p.m.e.) My goal is 3650-3700 f.p.s.
