Don't forget about your case head dimensions and the extractor hook dimensions. Depending on the caliber, you might also need to add a block to the mag well. You would be better off to rebarrel with the original as noted above if you are trying to keep it looking like an original. If you are wanting a .308, you would be better off to buy a used .308 unless you are dead set on using this rifle.Lothar-Walther Mauser barrels, new, exact specs as K98 originals, finished, only $250.
** and you can get these in a variety of calibers, including 308 Winchester ! **
You'd just need a gunsmith to screw it in for you and set the headspace.
That's probably another $100- $150.
I believe that he is talking about a full on custom build based on a bare action. Custom stock, exotic wood, rechambered, rebarreled with custom engraving and high quality blueing."Several thousand" for a rebarrel"? The last one I did cost around 600.00 with a kreiger. This was for a bolt gun and I know about the extractor slot that has to be milled into the shank on a Mauser barrel, but now way will it be 1000.00, let alone thousands.
. . . and I have some 8mm Mauser posted for sale here, Portuguese'70s mfgr. I will try to add the link.the reason I was thinking 308 is do to finding 8mm at a reasonable price. What I've seen is old Iranian surplus and corrosive at $2. a round.
