powder to use in m 300 WSM

[johnny2]

Just wondering what powder some of you may have found to be the best
in your 300 WSM rifles with a 150 or maybe a 180 grain bullet?
I have been using IMR 4350 AND h 4831

I have also gotten great results with re 19 and 22 in my 270 WSM.

4831sc seems to be king in the WSM's.

I load for 3 300WSM rifles and I have found Ramshot Hunteris the best choice for accuracy and velocity in all three. I am currently testing N-165 and MRP. Both look very promising.

64.5 grains of H4350 and your choice of 180 grain bullet

Wow, H-414. Never heard that powder recommended for WSM's. I have some of that. Do you have good luck with it?

Yes. I found good loads for H-414 in the Nosler manual. I have been using the H-414 in my 300 WSM with the Sierra 155 grain Palma(for an additional 100fps).I use this load for my long distance deer rifle. I imagine a lot of people would not like my choice of the 155 grain pill for long distance deer hunting, but I have found the load and bullet to be devastating, and very accurate. And the Palma has an excellent BC for a 155 grain pill.

I am also using the H-414 in my 22-250 with the 75 grain A-Max in a 1in8 Krieger barrel.

I started using the H-414 about 1-1/2 years ago, and I definitely like it better than what I was using. It also gives great case fill(which I prefer). It is a little harder on the wallet, but I find it to be very consistent. Tom.

Yea, I like spherical powder. Thanks for the tip.
