I have a winchester model 70 CRF action here, serial number is 35Amn01987. The rifle has an original barrel on it, from what I can tell, I bought it for a donor action and the seller bandsawed the barrel off a few inches in front of the action. Originally chambered in 30-06 in a sporter configuration. From what I can tell has never had any machine work done. I pulled the barrel off today, it is threaded 1.062" X28tpi. I'm just curious if anyone knows if some of them were made differently than the 1"x16tpi standard.
