[QUOTE="BUSTINDOGS, post: 1185035, member: 49798"] Might be on to something with the cyro to help the material during temp change, this should make for a barrel with same cold bore poi as a hot gun... Or at least better than what is considered good now? You wouldn't believe how temp changes metal untill you are holding plus/minus .0001 on 300 series stainless and checking it with a cmm. I could only imagine how much the bore and groove change on a rifle going from 50 degrees to 100 or better. [/QUOTE]
