[QUOTE="FURMAN, post: 1207940, member: 26535"] If I were you I would move to 180 Bergers with Retumbo. You would need a 9 twist and the correct throat so I am not sure how they would do in your 9.25. I have no explanation for the slow speeds but I will say that case is more efficient with a larger bullet and slower powder. My WSM shoots 180s at 2980 with 66 grains H4831SC in a long action with a long throat. I ran some numbers and it seems you 168s are seated pretty close to the optimal depth. The 180s would be a little more into the case than I would like. You could also try some 162s. [/QUOTE]
