Unintentional Case Forming Experience

[MS_1910]

Model 1924 Mannlicher-Schoenauer Carbines were made in 7x57 Mauser for the US market and 7X64 Brenneke for the European market where it was illegal to own rifles in military calibers. This is shamelessly plagerized straight off the Mannlicher Collectors website/Characteristics:

1924/1925 .30-06, 7x57, 7x64, 8x57JS, 8x60S, 9.3x62mm, 10.75x68mm Straight Butterknife Wing Safety carbine, rifle, and takedown steel plate with trap

1950 6.5x54mm, .257Roberts, 270 WCF, .30-06 US Straight Butterknife Wing & Side Carbine & Rifle Plastic

The M1924 Mannlicher Schönauer was originally chambered for 'the U.S. 1906 Cartridge' (.30-'06) only.

They were manufactured for export to the United States via the Sequoia Importing Company of San Francisco, California and Detroit, Michigan. Sources differ regarding how many were made, several say 1,000 were ordered but that far fewer were actually manufactured for and shipped to Sequoia. The M1924 and subsequent models of Mannlicher Schönauer rifles and carbines differed from the previous models as they had longer 'actions' (to accommodate the .30-'06) and a retaining ring was added to the Schönauer magazine that was lacking on the M1900, 1903, 1905, 1908, 1910.



They did not sell well, and many were returned to Steyr where the M1924 designation was ground away and replaced with a stamping of 7.62X63, the metric equivalent. Steyr continued to manufacture MS rifles and carbines (stutzen) on the longer actions, and did so in several metric chamberings which were stamped in the same location as the model designation had been on previous models. These are what collectors today refer to as 'M1925', and Stoeger sold as the 'High Velocity' model when they became the sole U.S. distributor of the Mannlicher Schönauer.

It should be noted that the previous models were all caliber specific and used Mannlicher Schönauer proprietary cartridges. All M1903 (as well as the prototype M1900) were chambered for the 6.5X54MS, M1905 were 9X56, M1908 were 8X56, M1910 were 9.5X57, AKA .375 Nitro Express Rimless.



Here is a page from the 1927 Stoeger catalog, notice only the M1903 through M1910 were offered by Stoeger at that time.



Here, from the 1939 Stoeger, the so called 'M1925' is offered as 'High Velocity'.
Calibers of .30-'06, 7X64, 8X60, 9.3X62, 10.75X68 are available:



And a (German) WUM catalog of about the same time,
listing the 7X64, 7.62X63 (.30-'06), and 8X60:



Here are pages 50, 51 of the 1939 Stoeger catalog:

15meter: I have tried two of the .375 Winchester moulds I have, 375248 and 375449. Neither one feed thru either gun. The flat nose catches. It needs a round nose or spire point. I understand Lyman used to make one, but it is rare.

The Mannlicher Schönauer models of M1903, 1905, 1908, 1910 (the proprietary cartridges) are very particular about what they're fed. The early model Schönauer magazines lack the 'guide ring' that was added with the 1924, then modified and continued on subsequent models.

On the early models, the profile of your entire cartridge should very closely match that of the originals. The cartridges ride in a cylindrical race of sorts created by the machined sides of the magazine well and the magazine's lower housing. The spool is also machined to the profile of factory original cartridges and holds them in order as they make their circular journey, but without a retaining ring the cartridges may shift into voids at the magazine well if not built to original specs.

MS 1910, thats some good info, It took me Years to find out the pedigree of my 1924 Sequoia, #51. Before the computer age, I bought it in 1970, I didn't have a clue what I had ended up with, just a really neat 30-06. I also have two 9x56 MS, Carbine and take down rifle. both are a hoot to plink with..

You know i had almost same type of experience. Left my magnification shooting glasses at home so used a plane safety glasses. Was shooting a couple different guns . Had my 41 mag and picked up a 357 cartridge and dropped it in well it went off and sounder a little funny and light recoil when i emptied the cylinder saw why even without glasses .

Years ago I bought a sporterized 17 enfield from an LGS. Took it home to clean it up and found a chamber brush for a 30/06 was quite loose in the chamber. Did a chamber cast and found it to be a 308 Norma. Made me a happy camper but I hadn't shot it with 30/06.

My M1910 is a 'factory' takedown model, as shown in the 1939 Stoeger:



Here it is, held by my Grandfather after taking a leopard:



Your 9X56, as you surely know, would be model M1905
