Howdy all,
does anyone have a source that will temper old Mauser small ring actions? I have a Spanish 93 that I want to build a light 250 Sav.AI on. Would there be any problems with warping, etc.?
Any help would be appreciated.

I just sent a 1909 Argentine action and bolt to Pacific Metallurgical in Kent Wa. for heat treating. www.pacmet.com

I am not sure about the pressure of the 250 AI, but I know that the pressure of the standard 250 Savage is safe to chamber in the small rings as is.

As long as the 250 AI's pressure is the same or thereabouts as the 7X57, then you shouldn't need heat treating done to it.

How about case hardening? It would sure be different.

Minkman, most Mausers were made of a lower carbon steel and carburized [case hardened].With the old ones you never know what you have especially war time manufacture .Years back when I was in gunsmithing school there was a heat treater that knew how to do it .They were carburized then heat treated. To make a custom Mauser without first dealing with heat treating is foolish since you don't want to put in all thast time and money only to have the bolt 'set back' !!

Thanks for the replies guys. This will get me started.

I'm reading P.O. Ackley's book on military actions. In his "blow 'em up" test he says re-heating added little to the pressure the receiver would take. He found some of the "softer" action would actually take more pressure before the let go due to the metal stretching more. The harder actions came apart like a hand grenade when they finally let go. I'll re-read that section again and if I mis read it, I'll correct this.

For those of you who want more info on heat treating Mauser action there's an archived thread here than covers it all in great detail.
Use the search function, keywords "let's talk heat treating" and you'll find it. I don't know how to provide the link for it, but it's there. It was started by vapodog and contains a wealth of information on this topic. It made a believer out of me.
