I like military Mausers. They spin my prop. So I bought a Czech Vz24 a couple months back in 7x57mm.
It was a real rust heap, but I spend a few days making it look closer to what it should look like for a Mauser built in 1930.
BUT, the bore is shot out! I mean gone.... It key-holes at 50 yards.
So I thought I would buy a cheap military barrel in 308 or 7x57mm or even 30-06. Nope, no such thing as a cheap military contour barrel,,, since they (the govt) are blocking imports of military barrels... (yeah , why)
Anyway, a new military contour barrel from Brownells is almost $200. I would then have to get the chamber finished and head spaced. Sweat on the rear sight sleeve and solder on the front sight base. So I would probably have another $300 into a $200 Mauser.
I could also go whole hog and buy a nice sproter barrel for about the same amount, rebend the bolt, and buy a Boyds stock or something similar.
Then I could make it into a 338-06, 9.3x62mm or some such thing...
Either way it will turn into a $500 to $600 gun that is really not worth that much....
