Yup I’ve seen that as well, a few barrel manufacturers offer cryogenic stress-relieving. I’ve never looked into the process personally (I’m a mechanical engineer), but at a high-level sniff-test it makes some sense. Forcing the material through a controlled process of extreme temperature change to force the crystalline structure to equalize its internal stresses. If it has any benefit over traditional processes, I’d expect it to be minor though. Probably one of those “give me 50% more money and I’ll make something 5% better” cases.

Ok it IS offered then for barrels . Good to know !!! Like i said id guess in the cf world of benchrest this is where i think the biggest benefit would be with faster rates of fire . I could see it tameing some crawl . I do know used on racing conecting rods weve seen increased durability , sizing stays truer and less failure of the rods , the big weak link . Theyre tougher in essence . This more so applies to rules that required production rods for limited classes where you look for every advantage you can find . Engines going "splat" are never cheap , even in restriced rule enviroments !!! It helped our programs . My gig is fluid dynamics so im the guy that punishes those rods . A DIY low dollar thing for barrels would be to pack it in dry-ice and let the barrel return to ambiant temp on its own a few days later . No big bucks involved and the slow warm up wouldnt induce stresses either . Wouldnt hurt a potential accuracy gain on a lighter profile muzzy barrel especially a button rifled one at all . Stiffer is what everbody is seeking with the fat barrels right ?? Nobody enjoys carrying them however . |
