I have been considering a number of short action WSM cartridges to build a rifle around for sheep hunting and just a lighter carry. I recently found Alliant is showing that the 7mm WSM with 162 grain bullets and reloader 26 is able to obtain 3171 feet per second out of a 24-inch Barrel.
This is about a hundred feet per second faster than any other powder in the other manual that I found.
Have others experienced this with a 162 grain bullet and reloader 26 out of a 7 mm WSM?
Here's the link to the Alliant page and a copy of the data
