Cryo-Accurizing Has anyone ever heard of this or had this done? I wondering if this is completely true that it will shoot more accurately and longer. Your thoughts? Cheers, Alex |

I have learned more about barrels than I ever thought I'd need to know here... www.riflebarrels.com/articles/barrel_making.htm |
As barrels heat up, they 'warp' and the harmonics of the barrel can change, therefore changing POI. Cryo-freezing a barrel relieves stress in the 'grain' of the steel, therefore reducing warp as barrel temperatures rise. Does it work? Yeah. But personally, I think it is one of the final accurizing steps to take once everything else is done. Cryo freezing a barrel will do nothing if the nut behind the trigger is not as tight as it can be!  PS. letting a barrel cool between shots will also prevent any shift in POI. |
