    Things In Vogue?

    Are cryogenic [freezing] stress relieving and moly coated bullets still in vogue?

    Speaking from an all out 100/200 yard centerfire Benchrest standpoint - Cryo-barrels have fallen from whatever they once were but there's a lot of folks coating their bullets with one thing or another.

    Zediker sells David Tubb coated bullets.
    That's also Superior Shooting Systems.
    I'm not sure if that's what you mean by In Vogue

    I'd be looking for coated commercial hunting bullets like from Hornady or Sierra, if anyone is coating and reselling. If I decide to use them. Freezing and moly coating were all the rage maybe 15 years ago. Was out of touch for some time and wonder if those things ever caught on and stayed on or were more flash in the pan developments. The Hart website doesn't seem to endorse them.

    Here is my 2 cents worth.

    I use a lot of Krieger Barrels. Krieger does a cryo treatment on all of their blanks. They have in house data that the treatment is a benefit it improving tooling life and relieving stress.

    I have heard that Krieger does pre cryo before machining, and a post cryo after the blanks are machined.

    Cryo treatment is not what I would call a "fad". More and more manufacturing industries are taking advantage of it's benefits.

    I have no opinion one way or another on coated bullets.

    I did a quick perusal of their site, but didn't find stress relieving mentioned. Maybe I missed it. I assume they do cryo in lieu of the standard heating in a vacuum. I do have one Krieger barrel I got maybe 12 years ago, but he wouldn't sell me a stainless
    barrel to put on a hunting rifle. Apparently he believed at the time that 30 below zero makes stainless brittle. I don't hunt when it's that cold anyways so I ended up with a chrome-moly.

    Cryogenic treatment is not "in lieu" of standard stress relief practice. Krieger and virtually all barrel makers stress relieve in an oven. The restriction on stainless barrels is only for the lightest profiles due to the tendency of 416 stainless to become brittle at low temperature. They did for a while offer the light contours in 410 stainless which does not have the same characteristic but they discontinued the practice.

    Rather than taking up a lot of space attempting to explain how Cryo Treating helps complete the transformation process in the tempering phase by transforming residule austenite, just read this link.

    It's not that long.
