I just burned through a box of Hornady 270 gr Heavy Mag while sighting in my new rifle, a Winchester M70 .375 stainless classic w/synthetic stock 24" barrel, I have a Leupold 3.5-10x40 scope. and I couldn't get a group tighter than 2.5" - 3" at 100 yds. I bought a couple boxs of Hornady brass and am ready to start working up a load this thing likes, I will be using 270 gr bullets for starters. and I am thinking IMR 4350 but am open for suggestions.
What works for you guys?
