Cyro treating barrels

This was a big (moderately) thing for a short time.  I'v read it does absolutely no good, and I've read it's the best thing since centerfire ammo.  Freezing the barrel according to the promoters is supposed to line up the molecules...or something.  It seems to have gone the route of moly bullets.  What do you think?

    According to Shilen's website, it's all a bunch of BS.  Of course, some people say Shilen barrels are junk, but they do sell a lot of therm.

    I remember when it was a thing...seemed like a bunch of bull then...

    That's my memory, too.  Gun Mags built it up with pseudo science, like they always do to jump on any headline.

    I've shot a few small things a long ways off.

    The website even admits that quality well made barrels will shoot accurately despite having stresses. I suspect those that would benefit the most would be folks with wandering barrels to begin with. Shilen makes pretty good barrels so I'm not surprised they didn't think very highly of this process.

    If you have the funds Gene and a crappy barrel you like but it doesn't shoot so good, give it a try and tell us how it works out.

    Btw, they do heat up the barrel. It's a process that ranges from +300 to -300 degrees. They computer control cycle it over a 3 day period. They also warn of other companies that don't do the process they (300below) do and actually hurt people's barrels.

    Seems interesting. I've never tried it and don't plan to either. :D

    I have had a few barrels cyro'd but only after a lot of research, that being the massive machine shop at the airline where I worked, seems the VP of maintenance had a lot of tooling ( drills, reamers, end mills, lathe bits) cyro'd, when the results were in the machinists claimed approx 30 to 50% longer life before re-sharpening, since I was able to get a 50% discount I had some barrels done. Can I tell you that the barrels were more accurate after than before, no i cant, all i know for sure is my 22-250 barrels that were treated lasted longer than those that were not.

    My advice is if you want to try it and money is no object, do it, but dont expect any miraculous change in accuracy.

    You mean there is still somebody out there selling that mumbo jumbo?

    So you heat treat the action and cold treat the barrel?

    Makes perfect sense.

    Yep.  It appears cryo treating requires REALLY cold temps to affect the structure of the metal, but only improves the hardness by 1 or two points, however, it makes the expansion of the metal when heated more uniform ( less variation ).  Does it really help the average gun?  No, in my opinion.  

    However, if I were a bench rest shooter, I am pretty sure I would cryo treat my barrel just because it MIGHT give me a tiny edge, and that is where those guys live. ( given my overthinking nature )  Shrinking a group by .125 wins competitions.  Changing my POI on the average game animal, not so much.

    Yet very few BR shooters cryo their barrels.

    Seems like BS to me, though one gun that I own does have the treatment.  Stranger still, that gun happens to be a Benelli Super black Eagle 3 shotgun.  How on earth the theories behind cryo treatment could benefit a smoothbore are even more perplexing.  They claim it produces 13.2% denser patterns, but I have a hard time digesting it.

    Heat treating the barrel of a shotgun for me makes about as much sense as buying my 87 year old mother a Porsche.

    Well if the policy was in your name and high enough may be worth considering.
    Save you from buying a mother's day present from here on to boot.

    From your link...
    ...with a cryogenically treated, longer choke tube.

    hmmmmm, a longer choke tube, so a more gentle exit with possibly less deformation of the pellets, but the fact the barrel got dunked in some liquid nitrogen is what makes the difference...
    Yeah, right

    Falls into the category of "Doesn't hurt, might help, irrelevant for most applications".

    Stress-relieving of steel is certainly a real thing.  Some steel needs it, other steel doesn't.  How do you know your barrel is in one camp or the other, and not suffering from some other dimensional gremlin?

    It's probably worth trying if you have a barrel that isn't living up to expectations after trying all the usual stuff - load development, torque adjustment on screws, etc..., as that's considerably cheaper than a new barrel.
