powders for 300 WSM

Hello gang I just picked up a 300 wsm and would like some ideas on powders to try. I used to have a 30-06 and if memory serves me right IMR 4350 was a good performer. I will be using 165 to 180 gr bullets and deer will be the main target and maybe an unlucky Catskills N Y bear..
Thanks Paul

Re: powders for 300 WSM

I have reloaded the 300 WSM since 2002 and I have found that a number of powders work well with 165-180 gain bullets. My favorite powders are N550, RL-19, and IRM-4831 in that order. IMR-4350 will also work. If you want me to be more specific let me know.

Re: powders for 300 WSM

Alliant has developed a new powder just for the WSM and WSSM it's called R-17. It's very hard to find but it offers better FPS than do the others.

Re: powders for 300 WSM

I have to agree with Shortmagman. The best by far I have found is the N550 and RL-19.

Re: powders for 300 WSM

Also consider H1000, I have good luck with it in my .270WSM. It is not as slow as R22 but slower than the R19. I found a few years back that R19 was a bit inconsistant between lots.

I will have to look up the R17, never heard of it.
