i am looking for some loading data for the 300WSM
using 150 grain bullets or 180 grain bullets.My man-
uals are mostly the older ones and i have not yet
ordered any of the newer ones.I have ballistic tips
and nosler's..i would appreciate any information
any of you have to offer..Also my powder supply is
getting low..right now i am thinking of using imr4350
or h 4831....with prices the way they are getting i
suppose i better get a big order out for supplies..
thanks again..............johnny

I load R19 In my wsm's, because it produced the best accuracy. In the past I've substituted H4831 for r19 as their burn rate are nearly identical. At any rate I would start with one of those two powders and work up a load.

I have been loading for a few different 300 WSM's for the last couple of year's. I switched to H414 this year for two of them. I am getting an additional 100-200 fps, and better accuracy. I am getting 3350 for a 26 inch Savage 12FVSS with the 155 grain Palma bullet from Sierra.

Here is a picture of my 300WSM. It is a real shooter. Tom.

Tom,

Thanks for the information..Sorry but I think that is one
ugly looking stock....But you gotta love them Savage
rifles..I have been a Savage shooter for years.
In fact I just got the new varment rifle in 22-250 cal.
I had one made into a 30-338 and used it in the 1000
yard shoots..Folks were pretty impressed with it..

My 300 WSM is a Vangard..I aint to happy with it but
it makes for a good deer rifle.. John

I use 69.0 grains of IMR 4831 under Barnes 168g TSX bullet and it = 3200 fps
We have used my Model 70 shooting this load to harvest a Bison andseveral elk.
Works great

For me IMR 4831 is a little bit faster velocity than the RL-19, but both are sub 1" inch groups.
