Re: Rock Creek Cryo Treatment
Cryo treatment removes about 6% of the remaining stress in a barrel. So if you have removed 90% of the stress in a barrel by heat treating and double stress relieving(as almost all 416r is) then you will only remove 6% of the remaining 10% of the stress in the bar, which is .6% of the total stress. Not worth the extra money, some also say you get more barrel life and it's easier to machine, but there are so many other variables that it doesnt seem to be worth the extra cost.

If you're set up for it in plant and use it as an in process step, don't see anything wrong with it.

Re: Rock Creek Cryo Treatment
I think that I read somewhere about TacOps cryo treating their action and barrel as part of their precision buildup.
I don't see any harm in doing so. Just not sure if the cost justifies the return.

Re: Rock Creek Cryo Treatment
You're probably the same as ordering your barrel stock as I am Brux, when the steel arrives it arrives dead. And you may rough profile the barrel before finishing internal dimensions as a lot of us do. Which is a stress relieving exercise or test in itself. Because we cut rifle, stress inducement due to manufacturing is a non issue. I have had bars and tubes cryoed to test out the voodoo without a deprecating result, nor a striking result in either process or groupage. But I haven't done a mass statistical test either, Jack may have and found it to his benefit.

Re: Rock Creek Cryo Treatment
As JR and the guys at Brux have stated, Cryo in most cut rifled barrels will have very little, if any, effect. (it won't hurt anything, just a waste of money). This is why most cut riflers contour before rifling. In button barrels or hammer forged barrels, when lots of stress is induced into the steel during the rifling process, and the barrel must be contoured afterwards, cryo can help remove a small percentage of the residual stress.
Cryo isn't a bad thing, but is it worth it? Up to your wallet.

Re: Rock Creek Cryo Treatment
Copy that, I will leave the Rock alone. The Savage heavy fluted factory .300WM barrel, on the other hand, may benefit from this. For the weight of this barrel, I should be seeing more consistent grouping. Still early to tell, as I have yet to properly bed the action, among other things. The initial round of load development has failed to produce consistent results, so I am considering all possibilititties.

Re: Rock Creek Cryo Treatment
If it's a Savage factory barrel the best option would be contacting Sharp Shooter Supply and getting a new prefit barrel as most factory barrels aren't really capable of shooting the best groups around.

Savvy Savage barrels aren't as bad as many of the factory sticks..
