[QUOTE="ForneyRider, post: 383880, member: 22519"] I have R19 and R22. R19 is a possibility. From the online articles I've read on reloading for WSM, R22 put up the factory velocities, and it has been my go to for 270 Win and 7mm Mag. I really don't think there is any magic in these WSM's, they simply have more case capacity. They are an overbore, esp the 270, and it requires a slow powder. One of the selling points of the WSM was that it's short fat powder column was more efficient. Well, I can get the 270 Win to pop 130gr bullets at >3100fps with 58gr of R22, and the 270 WSM requires 8-10 more grains to provide an additional 200-300fps? The 4350 speed powders, including 3100 and R19, seem to do quite well in load data as well. [/QUOTE]
