Home Forums Reloading Big Game Rifles 270 WSM range report

RL 22 is probably the worst powder that I have ever tried in my 270 wsm, I had to burn a pound and a half to find that out, it is very temperature sensitive, it's lot to lot performance is erratic. IMR 4831 works best in my 270 WSM with 130 gr Barnes xlc bullets, Ramshot magnum gives me top velocity with Barnes 150 gr X bullet and 150 gr Nosler partitions, I am getting 3/4" groups with the Barnes 150's. Going to test the partition load for accuracy this weekend, I put about 400 rounds through my rifle before I found the right loads. I am getting around 2980 fps with the 150's and 3250 fps with the 130's.
