What is a "Cutover"? I kind of think they moved towards standard threads when they opened up the receivers and started chambering the longer rounds. I rebarreled a few .243's and .308's with "V" threads, but don't remember ever seeing one with square threads. I sold a .300 barrel that came off a gun with R model wood that was "V" threads.
Fireball, You missed the one I was talking about. It was not finished yet and was done on a older receiver. I think the guy wanted $400. for a "Buy it now" deal. I asked a question and it was sold before I got an answer.
