[QUOTE="JR, post: 144554, member: 1965"] [ QUOTE ] [ QUOTE ] Jeff Your report is interesting. I just heard today that another company is useing that same CNC process and turning out some great barrels.( Satern Custom machining. )Sounds like a new trend. I think we'll give one a try in .338 7mmRHB [/ QUOTE ] I've never heard of Satern barrels, but if it's true, all these new barrel makers will force changes within the barrel making community very quickly. Famous barrel makers we used to use and trust will be force to change to modern machinery, update their procedures and practices or will quietly be pushed out. New names will take there place.
