Yes - bottom metal numbers do match bolt numbers. I suppose that could mean the bolt and bottom metal are from another rifle.......or not. The bolt and bottom metal numbers might match the original serial numbers that were renumbered. I think the whole renumbering thing has something to do with sporting rifles being used for military purposes (in local/regional conflicts like in Africa for instance) and remarked by arsenals, but really don't know. Would love to know more.

Any idea what the markings under the rifle mean? I assume 7,85 and 8,15 represent the bore and groove diameters in millimeters - but neither of these converts to either .318 or .323 unless my arithmetic is wrong. 7.85 mm = .309 inches. 8.15 mm = .321 inches. The 240 number is the rate of twist in mm. I think. No idea what the 15114, etc. mean.

I didn't pay a lot for the rifle and knew about the renumbering before I bought it. I actually like the rifle (never meant an Oberndorf mauser I didnt like!), and would love to shoot it.

stupid question - how do you slug the bore?

Thanks for the quick response!
