Re: Ramshot Magnum powder
If your shooting 100 grain bullets in 25-06 you don't have enough case capacity to use anything much slower burning than 7828. That S/C powder just spits out of my RCBS electronic measure.
Have you tried R-22. You would use about 1.5 less grains of R-22 than 7828 and my chrono speeds were nearly identicle
