The German standard
s.S. Patrone ("s.S. ball cartridge") was originally designed for long range machine gun use. It was loaded with a 35.3 mm (1.39 in) long, boat-tailed,
s.S. - schweres Spitzgeschoß ("heavy pointed or spitzer bullet") full metal jacket bullet and very well made.
[22][26] It was lead filled, had a gilding-metal-plated jacket, and weighed 12.8 grams (197.53 gr). The
s.S. Patrone had a muzzle velocity of 760 m/s (2,493 ft/s) fired from a 600 millimetres (23.62 in) long barrel and an operating pressure of 320 MPa (46,412 psi).
[...] the
s.S. Patrone became the standard German service ball cartridge in the 1930s when the German rearmament program started.
[...]with a G1
ballistic coefficient between 0.593 and 0.557 (ballistic coefficients are somewhat debatable) or a ballistic coefficient of approximately 0.295 (G7). When fired at the typical muzzle velocity of 760 m/s (2,493 ft/s) out of a 600 mm (23.6 in) barrel the s.S. bullet retained
supersonic velocity up to and past 1,000 m (1,094 yd) (V1000 ≈
Mach 1.07) under
International Standard Atmosphere conditions at sea level (
air density ρ = 1.225 kg/m3).
