Well, at least it hit the paper...

My custom Mexican Mauser arrived a couple weeks ago and yesterday I got out to the range with it. Shot a couple groups at 25 yards to make sure the sights were close then tried a couple at 50. I didn't have the courage to shoot at 100 yards. Truth is I have a real hard time seeing the target at much beyond 50 since my eyes are just as old as the rest of me.

Anyway, put up a 1/2" group at 25 and 1.5" at 50. This was using some nasty military surplus ammo I bought a few years ago. Dated 1970 it uses a 139 FMJ P/BT that clocks 2925 FPS from a 24" barrel (that's why I call it nasty). It is amazingly consistent with less than 5 FPS variation. No doubt I lost a little velocity in the Mexi's 20" tube and the report was intense. Still tinkering with the sights between strings.

I need to shoot it some more, and maybe it would prefer a heavier bullet. I will eventually give it a try at 100 when I work up the courage.

The 50 yard group: (This looks bigger than 1.5" but I measured it three times. Optical illusion or something.)

Some questions

First, what rifle with a 24 inch barrel did you use to clock over 2900 fps MV?
That is a very hot load for any 7X57!

Second, what Mauser model is the Mexican Mauser? I had one that was a Model 93. I was always told to use mild commercial loads in it, as it was
considered to be a "soft" action that should not be used with "hot" loads.

I sold the sporterized Model 93, but now have a modern, strong action 7X57 that I handload to 2,950 fps MV, using IMR 4320, in a 22 inch barrel, 139 grain bullets.

I have no need for FMJ military ammo, but I am just curious as to where you found it. I might buy some for punching paper, but would never use it on game.

That was probably the stated velocity for the uncut military rifle, I doubt the military would use ammo loaded so hot that it would be unsafe in their rifles.
I do hope that ammo wasn't corrosive.

Looks like an M98 action which would make it an M1912, an intermediate action specially for the 7x57. That's my best guess looking at the picture.
