Cryo freezing.. have you done it? What is your results?

[MDGrand]

I am thinking about Cryo freezing my 300 RUM 700 XCRII.. figured I might get tighter groups and some extended barrel life.

Has anyone here Cryo'd there barrel? If so, what is your rifle and results...?

Had it done on my Ruger MKII 6-7/8" 22lr side slab handgun barrel. Very accurate and seems bore has less fouling.
