A good powder for a .300 RUM

[pdawg]

I'm looking for a powder that will shot 3400 fps (or better) and will maintain 1/2" groups at 100 yds using Swift Scirroco bullets. A few people have already recommended Retumbo and Rl25 for me. Do you guys know of any other powder that i should be looking at?

Thanks for the help.

Try some WMR or 7828 the vel and accuracy is there.Also H1000 is a pretty good powder for this beast.

I have had great luck with R22. I am getting 3650 out of 92 garins with a 165 Hornady bullet. Hope that helps. Oh it is right at the max load for my rifle.

I should have mentioned I had no luck with Retumbo other than shooting a solid copper bullet like the Grove Bullet. Using a solid copper bullet may shorten barrel life so I have been concerned about that. I am working on R25 right now. I just have not had a chance to shoot any of the rounds I reloaded yet.

Thanks for the help guys. I'll be sure to try out each one.
