Thread: loads + powder 300wsm

recently added 300wsm to the long range arsenal and want to work up some hand loads. Reading up the various Reloading Manuals I see powders from 4350 or 2209 thru to RL22 or 2217. Have started with 2209, IMR4350 and 2213SC but wonder if double base powders like RL19 or 22 might give better results ? Any suggestions of loads and powders would be most welcome, I'm not chasing the last few fps but more interested in tight groups at decent velocity. Running a 231/2 in bbl. cheers
