Dave, the process he's talking about is one that entails the use of Liquid Nitrogen in freezing the barrel at super cold temperatures. This is used to provide a degree of hardness, AND is claimed to strengthen any metal exposed to it. Case in point, many companies use this treatments on blades in order to keep their edge sharp for far longer than an untreated blade might hold one.

I believe that such extreme cold (we're not talking about 25 degrees below here, but rather hundreds of degrees below zero) aligns the molecules of the metal all in the same direction, packs them in a little tighter and in the process fills voids along the atomic level producing much more strength.

This treatment is commonly used on gun barrels and has been noted to produce good results in accuracy.

Just my 2 cents....

Cryo deep freeze. Its for stress relieving a part that has been made in such a way that it creates stress in a part. Like turning the OD of a rifle barrel. Its kind of complex to try and explain it in a brief post. Cryo-Accurizing Ph# 801 395 2796 cost varies their are a few companies out there.Maybe $60.00 mabe someone will post a site?
