Never loaded for the 300WSM however 64 grs of RL22 is a VERY light load. QL calls the pressure in the range of 37000. Velocity in the 2700 range. Alliant calls max more like 73grs. You have an accurate 308W equivalent if that is what you are looking for.


As usual just my $.02

I'm loading 69.5gr of RL22 with 180gr Sierra Pro Hunter bullets in one of my 300WSM's and just shot a .97" group at 200yds last weekend with it. I'm loading 71gr of RL22 with 165gr Noslers in my Featherweight Win70 and it will shoot about the same at 200yds. My other 300WSM seems to like 71.5gr of RL22 with 165gr Hornady Interlocks. I have not shot it at 200yds on paper but it is sub 1" at 100yds.

I load mine with 69.0grs of Reloader-22 with a 165gr bullet.Mine started getting sticky with 71.0grs,so I backed off two grains.She will print nice little clovers if I do my part.

Ive loaded 67 grs RE22 with 180NBTs, 68 should work with 165s, though it might bea little on the light side yet.
