Re: H1000 vs H4831
I've been playing with my 300 win Mag and the 220SMk's. I've tried RE 22, IMR 7828, H1000 and Retumbo now. So far my gun likes the H1000/75.0 grains, win cases, Fed 215M primers. Just shot 9/16" group at 200 yards (three shots) last weekend. The velocity spread was 2 for the three shots. This is a factory winchester rifle. Velocity 2689 at 70 degrees.
I thing I'm done with the load testing, now going to move out to the 1000 yard range and test some more for groups.
