    anyone use rl17 or hy100 for reloading 300wsm, what kind of accuracy and velocity do you get. I reload for 300 savage 26" 300 kimber 24" and 300 tika 24". Any load data apperciated. ​

    Go to the Alliant web site for their load data for the 300WSM using RL-17. I am loading my Ruger 77 Mark in 300 WSM with RL-17 and 168 grain Barnes TTSX bullets. Alliant list 68 grains as their max with a 165 grain Speer bullets. I am getting just a little over 3000 ft/sec with 64.7 grains in WW cases and 215 Federal primers.

    My Ruger has a 22 inch barrel. I have shot 168 grain Berger out of my Winchester 70 Coyote in 300WSM which has a 24 inch barrel. I did not match the velocity that Alliant shows on their web site for 68 grains but 68 gains did give me over 3100 ft/sec.
