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.
a lot of f-class / long range boys run those bullets in 1:7 twist in 223REM with 30'+ barrels. with no problems.
I ran them out of a 7T 224V and had no issues with stability as low as 800’ and they were only going like 2425fps. You should have absolutely no problems at 22CM velocities even down to sea level.
I just got 1000 of them from Blue Collar Reloading this week.
Thanks for the heads up, just ordered some. Merry Christmas.
