Re: 338 Rem Ultra 30" barrel loads-wanted
I am told the longer barrel would not add chamber pressure, but would like the slower burning powders and have increased velocity with the slower powders. I got a e-mail from a 50 shooter that there was not enough case capacity for H50BMG and Retumbo was the slowest burning powder that I could use, those max loads were compressed loads. So I'll get some of the listed powders to start. I wonder if anybody has every loaded for a 30" RUM barrel, I can't be the first. The 30" is kind of the standard with the 50BMG and the Lapua shooters, maybe I screwed up. I got this for long range Elk hunting.
