At the time i bought my criterion remage 22 creedmoor they only had 1:7 twists so thats what I got. I want to try the 95 sierra matchking which is recommended to have a 1:6.5 twist. I should launch them out of the 26" barrel at about 3200-3250fps given what i have from the 90 grain bullets. Has anybody ran the 95smk in a 1:7 twist?
 
You should be fine. I am running a gain twist barrel that starts a little over 7 and ends up a little below 7. My velocities are under 2800 fps. With your speed, you may be in a sweet spot.

Your SG estimate with the Miller Equation is about 1.3 at sea level. It improves with more altitude.

I have 2 6.5 twist 26” Bartlein 5R barrels. They are on two different but similarly built rifles. I would be cautious of using 6.5 twist and trying to push them fast, I had issues with throwing jackets in both rifles. I think I was getting in the 3200-3300 fps range with the 95smk. I had to back it off quite a bit to around 3000fps to keep from throwing jackets. I wish I would have went with 1:7 twist.
