Tom, in the two 300 WSM's I've had H4350 proved to be the best all-around powder for 150-200 gr bullets. Other's I tried were H4831sc, RL19 and RL22.

I'll be doing some chronographing this coming week and will post. I took the tikka out yesterday tried H-4350 got some pretty good groups aroung 1/2" with 165 gr bullets. I was about at max on the powder but so far h-4350 seems to be the powder for this rifle.

I haven't tried anything but imr 4350 and nosler's.I WAS WELL Satified and the f.p.s.should be in the low 2900's this is a little faster than what my 30-06 is and it has served me well for several years.I don't have a graph so i'm just going by the book for a 24'' barrel.good luck.

I don't have the tikka but a friend does and he shoots 180 gr sst with R-22 saw him shoot a one hole group the other day.He was using 69 grs of R-22
I have the 300 wsm in a browning stalker and I use the 150 gr sst's in mine.IMR 4350 and H4350 shoot about the same in my browning.
