Then there is "cryogenic freezing". Any materials engineer will tell you that stress in steels are relieved by elevated temperatures (several hundred degrees), not by cryogenic temperatures.

I've read numerous claims of improved accuracy after cryo-treating. I had my SAKO .338 WinMag barrel cryo-treated in an attempt to improve its accuracy. It made no difference in accuracy. It still shot 2"-3" groups at 100 yards.
A Krieger barrel made it shoot under 1".
And, no, I didn't use any break-in procedure. I just took it out and shot a few groups with it and sighted it in, and cleaned it when I got home.
