[QUOTE="scheme, post: 2741258, member: 117961"] I got a McGowen prefit for a Ruger M77 tang safety last year. Debated whether to mess with rebarreling that rifle at all for a long time, but it has some sentimental value so finally decided to take a chance. McGowen was one of the only prefits I could find for that Ruger, and I was absolutely suspect that it wouldn’t headspace. I do a little gunsmithing with a buddy on occasion so we could fix it if we had to. For about $600, I got a custom contoured (matched the factory pencil contour out to .750 then straight to 24” so I could have enough shoulder for a can), fluted (to make up for a little of the weight added from the contour), threaded 7mm RM barrel. It screwed on and headspaced as tight as you could ask for. Minimal break in with some old ammo, then have only worked a little on a load. A little was all I needed. 400 yard ladder, found a group of 3 (.3 grain increments) that went under an inch total and about half vertical. Loaded the middle of those 3 and verified with 3 shots into about .3” at 100. More verification needed to have any confidence that it wasn’t just a fluke, but, I’m very happy so far. I have no loyalty to any particular barrel. Have Shilen, Kreiger, Bartlein, Hart, Shaw, Lothar, JP, Larue that I can remember off hand on bolt guns and ARs. This McGowen shoots as good or better than any of them. Just 1 data point, so not worth much, but I’d buy another. [/QUOTE]
