Nosler uses Vit N560 to test all their loads in 300 WSM. High velocity & great accuracy. I've also had good luck with Ramshot Big Game & the new Ramshot Hunter. All three powders are not temperature sensitive & show low Sd.

second the H4350. I have used it all the way up to 210s.

Go with the Fed 210 primer. Had bad luck with the 215 magnums. Win WLR might be good also.

Got the same rifle except in blue. I'm just starting to test N-550 with 165 gr bullets. Had good luck with R-19 and H-4350. I haven't tried H4831 or H4831sc in this 300wsm but in my custom with a 5c barrel 1/12 twist it's a pretty good powder. You will like that 5c barrel. I'm going to have another rifle done up with that barrel but in 1/10twist haven't decided what 30 caliber yet. Back to the Tikka got it this past summer and most groups have been 1" or less and velocity has been around 3000fps with 165 and 180gr bullets. Keep us posted as to what powder you like best.

Thanks for all the input! It sounds like the 300 WSM is not extremely finicky. I think i need to buy some H4350 to try. I may also buy some 560 as well.

Re: Need powder sugg for 300 WSM 1 in 11 twist

Excellent info everyone. I know with my 300 win mag primers made a suprising difference in accuracy. Yah, I know I need to test some for myself, but does anyone have a favorite primer? I see Ric likes the WLRM primers, and He no doubt proven that they work, but others swear by Fed 210M primers. For those that have listed H4350, Vhit 560, RL22, and H4831 (long or SC) as their accurate powders, what primers and bullet weights are you teaming the powder up with? I will try the WLRM mag primers as Ric suggested with the H4350 (I assume this is with heavier bullets such as the 190s Ric?).
