Re: 300 WSM Loads (Rookie Alert)
I have been using 66.5 great of RL17 behind 168gr TTSXs 3140 out of my A7. Sub moa and single digit es. Recently tried Superformance with the same bullet. Not much difference in speed. Had a box of 168 gr TSX so gave them a try with the Superformance. To my surprise they went 3200 fps. With the TTSX having a better bc, performance to 500 yds is virtually the same.
