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 ...
I'll be running this rig with a 26" Douglas heavy varmint barrel 1:8 twist. New to long range shooting and was curious if anyone can offer any load suggestions. I went with the H1000 powder and 180 grain bullets, Peterson brass.

N570 has generally produced slightly higher velocities over H1000 in the bigger 30s I have tested. .300WM, .300PRC, 30 Nosler, .300RUM. But is harder on throats in a rifle that gets shot "a lot". 20-30 shots a year, from an already short barreled (velocity handicapped) would be fine with N570 for a long time. My own 300PRC will be trying H1000 first with 215s. Unless it doesn't like it for ...
Good morning SH, I need some help choosing the correct load. Back story, I've ran load development with H1000, 56.2gr 2.3030" CBTO, but have ran out of...
