A few hours ago I got a present from a gunsmith friend: A heap of junk, but noble junk. The essential parts of a commercial Mauser , #104xxx, 1930, square bridge standard length action with a long 28” half octagon, ribbed barrel in 8x60. As often seen in Germany, badly rusted under the woodline post 1945. Inscriptions hardly legible. Receiver: “Waffenfabrik Mauser Oberndorf a.N.”, barrel rib “Mauser Werke A.G. Oberndorf am Neckar”. Outside reworked and reblued post-WW2. Barrel inside looks quite good except for an inch or so at the muzzle.

I intend to complete it with parts from my “junkbox”: fit an original B stock with triggerguard, Timney trigger and so on.

Only then I will shoot it for accuracy. If it shoots decently, I will leave it alone.
But if it does not shoot any more, what would you suggest? Shorten the barrel by a couple of inches or have it rebored to 9.3x62?
