Though the M76 fires its bullets at a relatively modest 730 m/s (2,395 ft/s) muzzle velocity, the 8x57mm IS cartridge loaded with aerodynamically efficient 12.8 grams (197.53 gr) military sS ball bullets still offers a supersonic reach of ≈ 950 m (1,040 yd) under ICAO Standard Atmosphere conditions at sea level (air density ρ = 1.225 kg/m³).
