Very cool. I'd like to have one.

It could have been that someone wanted to 'push' loads for the 9.5X57 without risking damage to an M1910 (or self)? Other wild guesses are that someone was particularly fond of the 9.5X57 but desired a wider selection of projectiles than those that function well in the M1910's Schönauer magazine, or perhaps just wanted a nice drop - block single shot in .375 RNE?

Here's a post from another 'site wherein someone is contemplating a 9.5X57 build on an M96 'Swedish Mauser':

I am thinking about having a 9.5x57 MS built on a 1907 Swedish M96. I like the metal on the old M96 actions and have a couple that were butchered up before I acquired them.

According to Wikipedia: The 9.5x57mm Mannlicher-Sch�nauer (MS) cartridge was adopted for the M-1910 MS rifle and carbine in 1910. The 9.5x57mm MS is also known as the 9.5x56mm MS, the 9.5x56.7mm MS, and the .375 Rimless Nitro Express x 2-1/4. Factory loads were manufactured with a 270-grain (17 g) round-nose bullet at from 2,150 ft/s (from the carbine) to 2,250 ft/s (from the rifle). (http://en.wikipedia.org/wiki/9.5x57mm_Mannlicher-Schoenauer)

According to Karl Kleimenhagen: The CIP piezo pressure specification for this cartridge is estimated to be 44,000 psi. This compares to 55,000 psi for the 6.5x55 Swedish. (http://kwk.us/pressures.html)

I have some unanswered questions about this cartridge.

1. What is the cartridge overall length? (I saw a post claiming it was 2.94 inches.)

2. What are the maximum case length and trim length?

3. Does anyone have a web resource for the cartridge drawing?

4. Assuming the overall cartridge length is <= 3.15 inch, is there any reason that Swedish M96 rifles could not be fitted with a new barrel for this cartridge? I have been told that the difference in head diameter is not an issue.

Thanks in advance for any replies.

He was close on the overall length:

One of the replies was interesting, as well:

ShortRifleFan;
I'm a gunsmith with quite alot of experience in 9.5x57 Mannlicher/Schoenauer.Over the last 30 yrs. our firm has built up several rifles.We have the reamer,headspace gauges,etc. My 1st 9.5x57 project was a rebore up from 9x56MS on a Mannlicher Schoenauer 1905 rifle. That bbl. was so corroded it was necessary. In retrospect I had originally thought about 9.3x57, but wanted an original MS factory chambering for both feeding/mag issues and asthetics.Any M96 action is more than ample for the load.While it is possible to overload anything , keep in mind that the working pressures are far below any limit on the M96 Swede action.I would choose a different action for other reasons, like a M98 just for cock on opening feature, not strenghth.Possibly a small ring or Portuguese Veguerio.
My standard load is 235gr. Speer semi spitzer bullet on a reformed 30/06 case.I use IMR 3031 at 46.0gr yields approx. 2050 fps. through chrono.Also shoot 48.5 gr,but can't find the chrono data.Chrono needs to be rechecked.In any event, I haven't any need to go faster ,I did use it to kill a young black bear , about 150 lbs. It performed well,other guys in the shop and our customers have used it on wild boar and exotics on a game ranch...all very dead.Repost to contact me.
