Has anyone done this? My office mate had it done to his 243 target gun and said it made a dramatic difference in groups.

I had it done a couple years ago on a 270 and it helped accuracy slightly, but I've noticed a huge difference in cleaning. It cleans up alot faster. It also seems to shoot well whether the barrel is cold or whether its warm. No POI change.

I have had this done to several of my personal rifles - as well as using a lot of Krieger barrels for customers, which are Cryo Frozen twice before I ever receive them. The frozen barrels usually shoot a little better - some shoot a lot better - and always clean easier. Best of all, they last longer - maybe as much as 50% - before the throat is gone and they need to be rebarreled. As a bonus, they machinenicely- the threads and the chamber cut very smoothly and leave a nice surface finish.

Can this cryo treating be done at home in a freezer, or does it need to be taken somewhere where God-awful temperatures are used? Liquid nitrogen or the like, for instance? Is the barrel treated separately, or can a barreled action be done as one?

You would need liquid nitrogen. Their web-site states temps of -350F, plus I believe the temprature-time cycle is an important factor as well.

I have one; the action and barrel (Krieger)were treated before I got it....so, no noticeable difference in POI, accuracy, etc.

It is, by far, the most accurate rifle I own.

Thanks---- Quite impressive---
