Cryogenic Treatment:

Opinions wanted: How much, if any, does cryogenic treatment affect accuracy, cleaning, barrel life, etc.?

I was going to answer your question then I forgot so I'll tell you what I've found out. Cryo is suppose to increase barrel life but not have any effect on anything else. I have talked to both gunsmiths and barrel makers and they all seem to agree on this. However some people do see and increase in accuracy because the barrel they had was under some stress and would shift around when heated up. Most feel though that if you have a good barrel it won't make that much difference. I talked to Scneider Barrels and he is testing two barrels out of the same piece of stock in a 25 cal., one cryo and one not, he said so far the one that was cryoed is showing more throat erosion than the none cryoed but doesn't know if this will stay the same through the full testing. I have also read where people have experienced accuracy gains with top notch aftermarket barrels after croying them so I guess you can draw your own conclusions. I guess for the price it's worth a shot. I probably just added to your confusion.

A few months ago there was some debate about deep freezing your rifles. The new American Rifleman did a pretty good job of testing this process in the new issue. Using several different rifles they fired and measured "before" groups, then they freeze dried the guns and fired "after" groups using the same loads.
Merry Christmas and Happy New Year !!!

I just wasn't finished reading the article yet. Now that I read it i'm totally confused.
The NRA took 9 rifles and tested them with several loads each, before and after being frozen. The results are strange. A few rifles improved their accuracy by over 30% (36% for one gun) with the tested loads. Most of the guns only had a very slight increase in accuracy. One rifle had a decrease in accuracy with all loads. The wierdest part is that a few of the guns had an increase in accuracy with Hornady bullets but a decrease in accuracy with Sierra bullets.
One rifle reversed this and accuracy improved with Sierras but decreased with Hornadys.
Overall with all guns and loads tested there was an average of 5.7%
increase in accuracy.
This is not what I wanted to read because I had my PSS freeze dried.
Confusing, no?

Kodiak, I also read that NRA article and didn't know what to believe in the end except that Cryo may or may not help. So this is what I think. If it shoots well don't mess with it. If it shoots bad and everything else is fine try Cryo.
