Twist rate on .223 CVA Stalker Elite

[Fully Involved]

Anyone know the twist rate on these? I have a friend that wants me to make some ammo for him, but I am currently loading .224 77gr Sierra MatchKing and 80 gr SMK (single shot). Does it have a fast enough barrel for those? (1:8 or faster).

I would have to go with "no". Fastest twist listed for any centerfire CVA on their site is 1:9.
