Large ring vs Small ring strength?????

Alright,..my experience is with newer actions for custom builds and I have a question about mauser actions for you guys that spend time with them.
I inherited what the smith told me was a 1910 mauser (had the clumbian military crest). The action did say waffenfabrik and orberndorf on the left side (IIRC). He called and told me it had the small shank even though it was a large ring and the barrel shank had to be turned down on the barrel I had sent him (19 1/2" stainless military contour, made on Mauser machines). I said "do what you have to do". My question is this,..with all the discussion on just how much pressure certain actions can take,...how hot can I run this action??? I chose the 7x57 to keep it "sort of" a period peice,..even though it will be set in a mcmillan stock.
I am having this rig put together for my father,..the action was his brother's and I figure he may get some enjoyment out of shooting a rifle that was made from something his brother once owned.

It will handle 7X57 fine. I'd say a small ring mauser would be fine up to anything in the 30/06 class- as that is what the 8mm is when loaded to full specs- if a 98 action. For a 2 lug action- a 95 or 93 model that is- I'd limit it to 7X57, 6.5X55, etc.
Your 1910 is a post '98 small ring and should have three locking lugs. I wouldn't run a high pressure magnum in that action but it will certainly take a high pressure standard case. The biggest thing on yur side is that it's Oberndorf. They are good quality steel.
The 7x57 that you are putting on there will take 55k psi. Which is about what it takes to get a 168 gr. out to 2700 fps. If he hunts in a heavily treed/brushy area and likes shorter barrels it will work against the cartridge. A long barrel is the way to go with the 7x57 I think. 24" will do fine though. FWIW I load my Mexican 1910(small ring post '98) right up to the max to get 2840 fps out of 140 gr. bullets.
EDIT:
Justin,
I should have read your post a little better. You have the large ring diameter with the small ring shank cut into it. This means you actually have more material than a large ring Mauser. It'll handle as much pressure as you want to throw at it. With the 19 1/2" barrel you are going to put on it you will be limited on velocity with that caliber. But, with a heavy bullet you can get all of H4350 to burn. Meaning if the twist is right(I remember a bunch of these at 1-8 1/2") it will easily stabilize up to a 175 gr. bullet. That's as much as you'll(he'll)need. Good luck on this project, I hope he likes it.
