While back found  in an old shed on relates property a Argentino Mauser.
It seems the origs. were 7x6something or other. This one reads as follows:
Mauser Modelo Argentino 1891
Manufactured Loewe Berlin
The bbl is stamped 7m/m B. Blindee
I assumed this to be a 7x57, ran a couple light loads thru it tied down to a heavy tire and looong cord. Nothing blew up, no ruptured cases or any case damage. My gunsmith is over 50 miles away so till I can get to him to make a cast to check it thought I would ask here. I thought about getting the stuff to do it with but never having done it thought would leave it to some one that knew what he was doing. Any Ideas? This gun is not worth a lot as it has been bubbatized a lot. Just thought ifin its a 7x57 might just make a cast bullet shooter out of it.

Gun Runner:  Some Argentine Mausers were made in the 7.65x53 caliber, but I suspect those were the Argentine Mausers made to Argentine specifications.  You may have an earlier one imported to Argentina that was in the original 7x57mm caliber.  If you have fired a 7x57mm cartridge through the rifle without any case deforming, you probably have one of the earlier ones.

Hate to say this friend but you still may wish to make the trip to your gunsmith to have the rifle checked for headspace and parts inspection - if she is still good, then you should be able to shoot standard 7x57mm ammo through it.  Sorry to read it has been Bubba-tized, but even in the 7x57, a Bubba-tized Mauser can make a good truck or back yard or camp gun.  Since Bubba got his hands on it, the value of the original may have gone down but it's functional value may remain.  HTH.  Mikey.

Mikey, thanks for the info. My daughter has a 93 mauser (7x57) that came out of awshwits (sp) concentration camp. Her great uncle was one of the first G.I.'s thru the front gate as the germans were using the back gate. A guard stopped to take a shot, great uncle brought his rifle home. Think I have a couple empty cases from it, will lite off a couple more with the argentine and mike the cases all the way around. Right will still have my gun smith check it but I had planned on keeping it in my jeep as a drag around gun. If nothing can shoot cast in it.

how is that Auschwitz Mauser for accuracy? i remember one holucaust survivior saying that they would bugger up the sights on purpose.

303, finally got a chance to shoot it 2 weeks ago. Running med handloads thru it.  Sights seemed right on and was just doing some informal paper and can shooting, everything off hand.  Mild recoil (course I weigh 215lbs) but daughter (145lbs) had no probs.  Sights dont seem to have been hammer adjusted or anything. BBl almost lookd like it hadent been used, course this was after a good scrubbing. Father in law said he had used it couple times to shoot deer, but outside of that I dont think it saw any use.  Wood is in good shape, just aged. It has no collector value, just family value as were it came from and how it was gotten.

Bubba may have really hurt you on that rifle,
There were few made for them in 7x57.
Does it have the "SHAKING HANDS" crest on the
top of the receiver?

[Gun Runner]

Sumner, not on top, but on the left side of the receiver, along with what looks like the initials MB (the M being on top of the B-done in fancy scroll). The mag. has a diffrent serial nr than whats stamped on the bbl.  Havant checked the bolt yet as still trying to get the release to let go. Stock also has a diffrent ser nr. Bubba varnished the stock with the action/bbl still in the stock.
At times I think people that do things like this should sergicaly have the items planted where the sun dosent shine.  :eek:
