RL17, quick load, & 300WSM? - 07/08/14
I worked up to 63.0 grains of RL17 with 168 TTSX (quick load max for this combo) but I only got to an average velocity of 2994 fps. QL projected max was 3080 fps. Would it be unwise to continue further? Of the powders I've tried (vihtavouri n550, n560, H4350, H100V, and rl15), this powder has been the most consistently accurate across all the test loads developed.
57.5 g of RL 15 has the single most accurate load thus far, with 3/4, 3 shot groups going sub-moa! with the largest group going 1.30" (ave. vel.=3030 fps) problem is I used all my RL15 up and can't find any up here in Canada. However, given how consistent my rl17 test loads have been to each other (.98"-1.35" across all 5 of my test loads) has me believing this powder could be the best so far in my rifle.
