with a 140 to 160 grain bullet. I'm sure some of you have worked considerably more with the cartridge than I have. Are there any powder(s) that are showing potential of being "THE POWDER" for the 7mm WSM??

Velocity is important but accuracy is what I am really looking for.

Lots o' good data there!

Steve,

I tried IMR 7828 first and have moved to RL 22 with both the 120 and 140 gr bullets. My load with the 140 Sierra SPT and 215's is up to 69 grs at 3250 fps. This load is right up there so be careful.

I have not shot 160's out of the 7mm WSM.

If you have IMR 4350 and no RL 22 you might try the IMR product as it's the accuracy powder in many loads.
