most everyone shot 14 twist for yrs. I have heard of some that are using 13.5t as well as the gain twist barrels, I feel sure that 13.5 or 14 twist will work for you.
 
I am about to have one built. Looking at Berger Projectiles, they are recommending 1:13 or 1:14 for all their match projectiles in 6mm from 68 grains down. I am going with 1:13.5. Not because I know anything, but because the gun smith suggested it.

the 13.5 is a good choice so is the 14 for lighter bullets
Ive seen possible world records shot with a 13 too.
I like the 13.5 twist.
 
i have been shooting a 12 twist a little with a 6mm grendel and old folwer 68gr bullets with excellent results. I have some 12 twist barrels on order so i think one of my ppc barrels this year will be a 12. I had a hall of fame shooter tell me one time that a 12tw is a OK!!! Lee
