I would like to add a suggestion: I have a Mark 77 in 30-06. Before I had it cryoed it had a average pattern of+10in @ 30 yards, ammo:150 grain different manufactures. After cryo the pattern is less than an 1in @ 100 yards, ammo 150 grain with a unique patina.
You probably won't get the unique patina but you will get a sub MOA barrel.
