The 9.5×57mm MS is also known as the '''9.5×56mm MS''', the '''9.5×56.7mm MS''', and the '''.375 Rimless Nitro Express (RNE) × 2¼''' (primarily in [[England]]). The cartridge may have been created by Westley-Richards and Eley in 1908 (rather than by the Oestereichischer Waffenfabrik-Gessellschaft, Steyr (OWS) (Austrian Arms Manufacturer-Association, Steyr)), but no production rifles in this caliber have been found prior to the M-1910. This development by or on behalf of Steyr was probably an answer to the development by the noted British gunmaking firm of Holland & Holland in 1905 of their [[.400/375 Belted Nitro Express]], designed for their specially modified Mannlicher–Schoenauer rifle (they imported the actions from Austria, but built the rifles in house). Whether the development of the 9.5×57mm Mannlicher–Schoenauer cartridge originated with OWS or with Holland's British competitor, Westley Richards certainly was the principal promoter of the new 1910 Model Mannlicher–Schoenauer rifle as evidenced by catalogs of the time. The 9.5×57mm MS is the last pre-war proprietary cartridge by Steyr and their most powerful until the recent advent of the .376 Steyr, which has its antecedents in the 9.5×57mm.{{Citation needed|date=August 2007}}

Factory loads were manufactured with a {{convert|270|gr|singadj=on}} round-nose [[bullet]] at from {{convert|2150|ft/s|abbr=on}} (from the carbine) to {{convert|2250|ft/s|abbr=on}} (from the rifle). This performance ranks the 9.5×57mm on par with or superior to similar medium-bore cartridges such as the [[9×56mm Mannlicher–Schoenauer]], [[9×57mm Mauser]], [[.35 Winchester]], [[.348 Winchester]], [[.358 Winchester]] and [[9.3×57mm]]. It was superior to the well-established British .375 Flanged Nitro Express, which only developed about 1950 to 2000 fps with the same weight of bullet, and treadtrod closely on the heels of the well-regarded [[.400/350 Nitro Express]] and [[.400/360 Westley Richards]] cartridges, howbeit these benefitted from a bullet weight of significantly greater sectional density. Since this is normally shot from a {{convert|6.5|lb}} rifle, the [[recoil]] is quite vigorous. The recoil energy of {{convert|30|ft.lbf|J|abbr=on}} from this combination is about 50% more than an average American [[.30-06]] rifle, but light by the standards of other African game cartridges such as the [[.375 H&H Magnum]].

Cartridge cases are available from specialist dealers in obsolete cartridges. However, cases are easily reformed from the nearly identical [[9.3×57mm]], or the [[7.92×57mm Mauser]], bothby ofresizing whichin full-length dies and trimming to length. Both aforementioned cartridges remain in production and continuing popularity in Europe which ensures a ready supply. There are no unusual considerations for handloading this cartridge. Any modern bullet of .375 caliber from 235 to 270 grains will work well, although bullets that intrude deeply into the case may be undesirable due to the relatively small case volume. Heavier bullets of 300 to 350 grains are not advised for hunting because the muzzle velocity will be about 2000 fps or less, which is insufficient to provide normal expansion in most contemporary bullets (which have much thicker jackets than bullets manufactured in the early 20th century).{{Citation needed|date=June 2022}}

ItThe 9.5x57 Mannlicher Schoenauer in the model 1910 rifle was considered by some African guide-hunters to be an ideal [[lion]] gun and cartridge combination in the years just prior to World War I.{{Citation needed|date=September 2010}} Finn Aagaard recorded that the 9.5x57 Mannlicher Schoenauer remained popular with settlers in Kenya in the 1950's and 60's for general plains game hunting.

Part of the reason the combination was highly regarded was the handling characteristics of the carbinerifle it was chambered in. The Model 1910 was available in rifle and carbine form and a take down version was popular. The Mannlicher Schoenauer model 1910 was light, well balanced, and had front and rear [[sights]] that were ideal for “snap” shooting.{{Citation needed|date=September 2010}} The front sight was a “[[German silver]]” bead that was visible in almost any light and the 2-position, folding rear sight was a wide spaced “V” (which made it easy to align the sights quickly). There were numerous alternate sights available from the factory and the aftermarket. The power of the cartridge (for stopping dangerous game quickly) was also praised.{{Citation needed|date=September 2010}}

As with most of the proprietary Mannlicher–Schoenauer cartridges, with the notable exception of the 6.5×54mm MS, the 9.5×57mm MS cartridge has not been produced by anyone other than [[Kynoch]] since the beginning of [[World War II]] (and only sporadically from them and their successors).{{Citation needed|date=June 2022}}
