I don't rememeber a lot about what I burned in the 7WSM,but pretty sure it was RL 22.I am working a lot lately with RL25 in a couple of 7mm mags, a 7mm Rem Mag,and the 7mmDakota,and am getting very good velocities in both with 160 gr bullets. I see no reason it should not do very well in the WSM,especially with heavy bullets of 160 gr or so.




The 280 Remington is overbore.

The 7 Rem Mag is over bore.
