Mauser 7.92x57 ammunition
The regular sS projectile had the following penetration performance: 85cm of dry pine wood at 100m, 65cm at 400m, 45cm at 800m and 10cm at 1,800m; 10mm of iron at 300m, 7mm at 550m; 5mm of steel at 100m; 3mm at 600m. The second most used type was the SmK (Spitzgeschoss mit Kern = "pointed bullet with core") bullet that measured 37.2mm, weighed 11.5 g and contained a hardened steel core (about 8% of all produced 7.9mm rounds).
Another type was the SmK L'spur (L'spur = Leuchtspur = "bright trace" = "tracer") bullet that was the previous type combined with a tracer that burned for 800 to 900 m (a little less numerous than the SmK).Tracers were placed at every seventh round. The lS (leichtes Spitzgeschoss = "light pointed bullet") which had an aluminum core and therefore weighed only 5.5g which resulted in a higher speed of V0 = 925 m/s but of course also in a shortened total range (the bullet was used mainly in the air defense role; about 4-7% of the total production), the lS-L'Spur which with a length of 37.2mm and a weight of 6.1g was again the tracer version of the lS (less than 1% of total production). A version produced mainly for use with the MG 17 as aircraft armament was the so-called V-Patrone which had an increased powder charge that increased the V0 by 15%. This ammunition type was available with the PmK projectile ("Phosphor mit Stahlkern" = "phosphor with steel core") or with the B ("Beobachtung" = "Observation") projectile contained a little phosphor and exploded upon impact, the latter ammunition type was also known as the B-Patrone and was used as an incendiary round; both types are not counted in the 7,9mm production.
The final and most interesting (for our purposes) bullet
type was the SmK(H). The H stood for Hartkern (hardened core), this was the armor piercing
version of the 7,9mm Infanteriepatrone. The projectile had a length of only 28.2mm,
weighed 12.5 g and contained a tungsten core that was 22.5 mm long. The propellant
gunpowder of the shell was increased to 3.6 g. The bullet had a penetration power of
almost 20mm of plain steel at a range of 500m (90° impact angle). However, production of
this ammunition type ceased in March 1942 because of an acute shortage of tungsten; still,
SmK(H) cartridges continued to be issued to the troops as late as February 1943. while it
was still inproduction, this ammo type accounted for 1 to 2 % of the production of 7,9mm
Infanteriepatronen. When the machine guns used the normal sS ammunition they achieved an
armor penetration of up to 10mm and more at close ranges.
Mauser 7.63x25 ammunition
Their energy lies a quarter below the Mauser and so tallies the 7,65 Mannlicher, which outwardly like is, which various european ammunitionfactories supplied until end thirties. Both cartridges are today, only distinguishable from the bottomstamp, collector's items; to shoot the corresponding and valuable pistols just with 7,63 Mauser, shall not occur to anyone. Against that are the 7,63 Mauser and 7,62 Tokarev of 1930 fully compatible, at least on paper, but also there not quite, then latest with the polish pistol came here problems (see "Differing Experiences"). Maybe, because the Mauser was already deplaced by the 9 mm Luger, the russians cribbed, started to make the cartridge for the, just in the then new soviet union introduced, Bolo Mauser, didn't bother to take care about any changes, through which for instance the 9 mm Makarov differed from the 9 mm Browning short.
Though the C96 here in Germany functioned as a stopgap, she found with her 7,63 Mauser cartridge worldwide spread and much awareness at the spanish, chinese, korean copyists, also when those widened the cartridgeselction to .45 ACP. She could maintain her position as the speediest factory pistolcartridge after .357 magnum appeared; comparable with the later is she not at all.
9mm Luger Parabellum
In 1897 George Luger, an employee of DWM, demonstrated the Loewe-Borchardt pistol to the US Army. Using constructive criticism provided by the Army's rejection, DWM and George Luger substantially redesigned the Borchardt action and its cartridge. The result was unveiled in 1898 as the Luger pistol in 7.65x22mm (.30 Luger or 7.65 Luger). It was immediately adopted by the Swiss government. The beautiful arm was The Mauser 00 in 7,65 Luger.
Several years later the German Navy officially rejected the 7.65x22mm cartridge. As a result DWM developed the 9x19mm Parabellum cartridge in 1902. The 9mm cartridge and the 9mm Luger pistol were adopted by the German Navy in 1904. The German Army accepted them in 1908. Two enduring designs for 9mm pistols arrived on the scene 30 years later: Browning's M1935 High Power (1935) and Walther's "double action" P38 (1938).
7.65 Browning (.32 ACP)
Even though many other cartridges enjoy far greater publicity, it is thought that more handguns have been chambered for the .32 ACP than for any other. It is estimated that during the first 10 years of the .32 ACP's existence, Fabrique Nationale alone produced over 500,000 pistols in this caliber. Practically every minor and major manufacturer of autoloading handguns in the world have built millions of small pocket autoloaders in .32 ACP with famous names like Walther (PP&PPK), Mauser, Colt, Remington, Savage,and FN/Browning on the list. The groove diameters of barrels in this caliber can vary from .308 inch to .313 inch among the various manufacturers.
