cryogenic treatment and accurizing

[Mr300]

Does anyone know if this realy works? And if it does, is it worth the money?And how much longer will it make my barrel last?

Also, a friend of mine told me about a way to accurize my barrel by taking it to a machine shop and/or a gunsmith and have to bore re-drilled. Is this for real or is my friend just blowing smoke up my ass?

Thanks!

I've never seen any evidence that cryo treating a barrel was beneficial.

Your friend is blowing smoke. Not the dumbest thing I've heard, but it ranks up there.

Here's the response I got..

While i have never dealt with cryo'd gun parts, I have tested the difference between cryo-treated brake rotors and non-treated rotors. The untreated rotors only lasted about 1/3 of the time that the cryo'd ones did. There was no difference in stopping difference or brake fade at extended high speed events.

I would think you would get a longer wearing barrel as well but that is just my educated guess.

Cryo rifle barrels will usually see some improvement in accuracy, and will also be easier to clean. Cryo'ing a handgun barrel is a waste of time/money. YMMV

The concensus on Rimfire Central and SnipersHide is that cryo is beneficial to some barrels, but not all. If you're talking about a rimfire, yes, the bore can be drilled and a liner put in place, if it is "shot out". If you're talking about a centerfire, that's a fairly tuck farded way to go about it. Chopping 1-2" off the end and re-crowning the barrel may be a big help, especially with Rugers, tho'...
