    So a rifle I am having built is about to be completed and I'm looking into some load data. It's a 260 remington with a 24" benchmark barrel 1-8.5" twist. I am planning on shooting 140gr AMAX's for the majority of its loads; with that, the leading powder candidate is H4350, but I am curious about RL-17. It seems I could get better velocities with it, but I hear its temperature stability is questionable. I was wondering if anyone knew just how unstable and how they liked using it? Also, I hear it tends to erode throats a little faster than, say, H4350. Is there any merit to this? Thanks.
