Have a 1900 era Mauser in 8mm commercial. Beautiful old German sporting rifle. Want to bore the barrel and chamber to 35 Whelen, as the 8mm cartridge is obsolete. Who is a good gunsmith to send this rifle to? A gun making firm known as Geiger built the rifle. Rifle won't chamber a 8X57 chamber is too large.

If chamber is too large then 8x57 should chamber, so I’m confused??? Slug the bore and verify whether it is .318 or .323 bore size, there is nothing wrong with the 8x57 it is essentially Europe’s 30-06. If you’re just looking to change calibers then by all means go for it, but SAAMI spec for the round is underpowered compared to euro spec, due to so many weaker actions out there and them feeling the need to protect us from ourselves.

Also confused by this. I'm not following how a chamber can be too large to chamber a cartridge.

JES Reboring in Oregon is the go to guy for this type of work. However you might wish to find a better donor. A 1900 vintage Mauser is getting a little long in the tooth. A "beautiful old German sporting rifle" is often a thing of beauty and best left alone.
I agree with others, in that the 8x57 is not obsolete, but if the chamber is too big, it may have been rechambered to a longer round already, like 8mm/06 or even 8x64s.
Chamber cast is called for either way.

I might be wrong, but it sounds like it’s be a lot cheaper to just rebarrel the action. The Mauser is pretty straight-forward for a rebarrel/chamber job and you’d likely get a better end product.

You may have an 8x60. How exactly is the chamber too large? In diameter or length? 8x57 obsolete? Hardly.
Danny Pedersen or Jesse Occumpaugh can rebore.

It might be a .318 groove barrel and the chamber wont accept a .323 bullet into the throat.
Just a guess. Doesn't mean I am correct.

Actually far cheaper to rebore with JES. $250 for the rebore and his turn around is fast. I don’t think you can get a rifle rebarreled and blued for anywhere close to that. Had one done by him several years ago and it was 10 days from the day I mailed it to the day I got I back. Reboring keeps the original barrel intact on the outside so you loose none of the original character of the rifle and no reworking the stock if the barrel profile doesn’t match the original. Ezekiel38, Definitely need to cast the chamber on that Mauser. As was mentioned it may have been rechambered. |

8x60 was a common rechambering in countries not allowing “war time” calibers.

Sorry guys additional searching, Pitting on and in the barrel the rifle is an 8X64. I've left three messages with JES over a two week period prior to this post with no response so it sounds like a rebarrel.

That would make a wonderful 9.3mm...

Just send it to JES with a note and a check. He'll take care of you.
About 1/3 the cost of a new barrel, or less, and maintains more originality.
I don't know what chamber would clean up a 64mm case. 35 Whelen would be cutting it close.
