Brazilian Mauser keyholing

[Ithacaman]

I recently acquired a good looking Brazilian Mauser, Model 1908, in 7MM Mauser.

It keyholes (lead not spiraling through the air but tumbling instead) with the modern factory ammo I have tried so far.

There is also a problem opening the bolt after firing. It takes a good deal of physical effort.

Is there any hope here? Any suggestions? Or do I now own a wallhanger?

 

[dakotasin]

what are the specs on the ammo you are using?
did you have the gun headspaced?
no, you don't own a wallhanger until you set the lugs back...

No expert here, but I'm wondering if the barrel crown is in good shape and even.

Otherwise, have you tried more than one brand of ammo?

These guns tend to have shot out barrels, start with head space check then after a good cleaning get a strong light and inspect the bore/crown. If the barrel looks like a sewer, don't give up with out a trip through an Outers Foul-out rig. The crown is easy for a gunsmith (or a handy guy with a crowning fixture) to straighten out, and not a bad idea anyway.
Is this a DWM mauser? These are great guns!

Thanks Gordon

This gun is indeed a DWM Mauser and I really do like it. I'm in the process of doing just what you suggested. Thanks so much for the advice.

About the time I get rid of any military Mausers I get right back into them. They're potoato chips. You just have to have more.

Well....

I would figure out that hard-opening bolt first. Can be a sign of HIGH-pressure loads.

What ammo are you using?
