History
History
The round was derived from the 14.5×114mm round by necking it out to 23 mm. The original rounds used a lower power charge of 33 g of sw 4/7 powder and achieved 690 m/s at a maximum pressure of 294.3 MPa. In 1954 an improved ammunition was introduced, featuring better projectile design and ballistic properties. The newer rounds have a powder charge to achieve 720 m/s.
