Cryo Freezing Barrels

Has anyone tried this cryo freezing (or whatever it's called)? I talked to a guy today who said it stopped his point of impact from wandering as the barrel heats up as is sometimes the case on lightweight barrels. Anyone have any informed opinions?

Thanks, that helped to answer one of my questions. My big concern is having to develop another load, but the walking point of impact is a pain in the behind if the thing needs to be sighted in after travelling which is why I'm considering it. For hunting it's no big deal - I can't remember taking more than two shots at anything.

I've been told that cryo treating a barrel is a good way to give somebody else your money.

A good barrel won't need it and a bad barrel can't be helped by it. Besides, how much of a performance gain does a hunting rifle need?

It's not a performance gain in terms of accuracy that I'm looking for, it's to stop wandering as the barrel heats up, and that's only for sighting purposes just so there is no guess work. In other words where the last shot hit is where it is going to hit the next time. I've had small difficulties with this barrel in terms of "walking" while checking the zero and that's what I'm trying to eliminate. I don't want to spend a half day of a 6 day hunt sighting in, and I hate guess work. I'm not one of those guys who is happy with 'somewhere in the ball park' when I've got limited time to hunt in the good places. I met a guy at the range with the same rifle I had (and the same stringing problem) who said it stopped his from wandering. Just wondering if anyone has heard of this being the cure for stringing.

I'm neither a physicist or an engineer but I don't understand how cryo treating a barrel will change how it heats up while shooting. I'm not saying it won't, I just don't understand it.

The vast majority of rifles and ammo will have a cold bore shot (first shot of the day) that has a point of impact that is different from the rest of the shots. A high quality barrel and ammo will lessen the difference but not eliminate it.

The way I do it (this is just me) is I remember that the cold bore shot on my .30-06 is 1moa high and 1moa right. I do just little bit of hold off with the cross hairs. The next shot will be close enough that I can go back to using the cross hairs.

Cryo Freezing Barrels

I haven't heard a lot about it in some years but I'm in Calhoun's camp on this one. Many years before cyro became the rage, I had a Parker-Hale that walked shots all over as the barrel heated. The explaination I got for it was that on a lot of the older rifles, the barrels were not stress relieved. It seemed that when the barrels were made, at some point, there was actually stress in the steel that changed the properties of the barrel as it heated. I don't know the truth tho that and that was the only rifle I ever had that did that.

But somewhere along the way, before cryo treating, I read that all ballers are stress relieved now. Then along came cryo treatment that claimed to cool the barrel to 300 degrees and as I recall further stress relieved the barrel. I don't know and I don't hear a lot of people doing it.

I have read a few reports in the past like the one posted above but figured I should go back and look at it. The thing I have not found in any of these reports is where they take a rifle shooting 2" groups and turn it into a 1/4 min rifle. In fact as I recall every rifle tested was always some super shooting rifle before the treatment and the gain in accuracy was minimal. Maybe non existent but rather due to a difference in shooting conditions? I think in the report above the writer claimed an improvement of .14"? To put that in it's proper perspective, I just measured a business card laying on the table and it is .12" thick.

I think after investing the money in cryo treatment, .14" improvement at 100 yds don't amount to much. It would be interesting to see someone do and report the results on an average rifle, say shooting consistent 1 1/2" group's.

Maybe I'm just being too finicky, it's just that I got invited on a once in a lifetime hunt next year and it has pushed me to the edge of obsession. I don't expect perfection out of a rifle, but I've noticed these lightweight barrels tend to be a lot more fussy. The rifle has been good so far and maybe I should just quit shooting paper and get on with it.

The trouble is that I'd like to be able to shoot more in the summer time heat (when I have a lot of time) and know that every shot is going to the right place rather than thinking "was that me or a walking barrel?" Truthfully it's never been so bad that it wouldn't hit what I was aiming for, it's just part of my personality to show up prepared without any doubts. I know the rifle is accurate, but I also want to know that I can put every shot where it belongs, and the stringing tendency screws up my practice. Also, I'm a firm believer that when invited as a guest it is just good manners to be a good shot and to show up with equipment that is dialed in.

I really hadn't considered cryo freezing until I met someone who had it done and I watched him shoot a warm barrel past the point where it normally started walking and it no longer did it. Keep the posts coming.

I recently saw a show on the discovery channel where they were talking about this new machine gun that when they cryogencally treated the barrell it got rid of the barrell over heating, It would still heat up but wouldnt ever turn red no matter how many rounds went through it.
