I have two all-weather M70's (7wsm and 325wsm) that I would like to re-barrel with carbon wrapped. Do these exist? If so, what manufacturer? Thanks in advance.
I don't think they exist. I would think it would be to hard to get them to time correctly with the extractor cut. Plus Winchester has 2 different thread sizes
You can buy blanks at several places online, there's a few retailers on this site. Have the gunsmith of your choosing thread, chamber and headspace.
