CryoFreezing Results

A while ago I thought I had a barrel walking problem but it turns out I was mistaken and the rifle is perfectly fine. But in the process of figuring all of this out I had the action and barrel cryo frozen which they claim will cure such a problem. I figured it couldn't hurt and for 100 dollars I would double or triple the life of the rifle.

I've had the rilfe out six times and here's what I've found: As far as accuracy goes it changed nothing I can see (it was already plenty accurate), but the surprising thing is that it virtually eliminated copper fouling. I have put forty rounds through the thing so far and there are only a few tiny streaks of copper that I can see, whereas before the fouling was very obvious. Not that I consider a little fouling to be the arch enemy of accuracy, but for high velocity rifles that are more prone to a lot of fouling it may be worth considering.

In the meantime, I have spoken with people who swear it does reduce wandering barrels (including firearms factory representatives), and I've run across one legitimate case where it provided great results in accuracy improvement. At the very least I at least doubled my barrel life and cleaning is a snap. Just thought I'd pass it along.

I don't know much about cryo feezing, but as far a copper fouling goes, it is inevitable in all rifled barrels. Some are more prone than others. I actually never have thought of a little fouling as anything bad at all. In fact I have a few rifles that actually tighten up after a few shots worth of fouling have been left in the barrel. When your rifling starts to disapear, then copper fouling is a real enemy to accuracy. But, a little bit of fouling does nothing to diminish mine.

No of course a little fouling is not harmful at all and the average hunting rifle will no show any ill effects, but for those who shoot large quantities out of rifles such as the 220 swift where fouling can be accumulated to the point where it does do harm this may be a great option.

Sound like cryo-freeze also make the barrel more resistant to wear and burn-out. If that's true, then barrels chambered for cartridges like the .220 Swift will benefit from it. As you may know, it doesn't take many rounds for a .220 Swift to start wearing out accuracy in a normal barrel. Though I must admit that the .220 Swift is my favorite of the varmit sized cartridges.

Yup, that's my point for making this post. For 100 bucks or so you can increase barrel life 2 to 3 times over normal and not have to pay for a bunch of copper solvent (much less invest the time in removing copper fouling).
