Filman, I've used RL17 to good effect in the 6.5 CM, 7-08, 270, and 300 WSM.
My opinion is, like RL26 and Big Game, many run RL17 powder too "hard."
In the 300 WSM for instance, my "go-to" load was 64.0 H4350 with a 180 @ 2,980 fps. I found that RL17 was at its best with 64.5 gr's with a 180 for 3,030 fps. One can go a bit highert higher, but I felt beyond 65.0 was over-pressure.
Basically, I think you can add .08% +/- to your book H4350 load to arrive at a viable, sane RL17 load.

Thanks for the reply to my post Brad, that's good to know. I don't think RL-17 will do what it did in my .250 in many other cartridges. For instance, it didn't have quite the same effect in my .257 AI. It did good but nothing spectacular. But in my friend's 6mm and my .250 it was sort of over and beyond without the excess pressure.
