BASIC TECHNICAL DATA AND PARAMETERS
• a brass cartridge case
• a projectile composed of the following elements
• a brass jacket
• a lead core with antimony added
• a non-corrosive Berdan/Boxer primer
• a propellant charge
Cartridge weight 23,2 ÷ 24,5 g
Cartridge length 70,2 ÷ 71 mm
Projectile weight 9,35 ÷ 9,55 g
Propellant charge weight ~ 3,0 g (46,30gr)
Average velocity of the cartridge V25 = 825 ± 10 m/s
The maximum chamber pressure (using piezoelectric method):
P max highest ≤ 400 MPa
P max mean ≤ 365 MPa
An average accuracy of gunfire for cartridges RS while shooting from the ballistic barrel within the distance of 300 m from the muzzle, is estimated at RS ≤ 9,2 cm.
