Wikipedia's D-30 table lists OF-462 at 21.76 kg with 3.675 kg of TNT and 690 m/s from maximum propellant charge, while the A-19 ammunition table says the gun could fire 122 mm howitzer shells and lists OF-462 at 765 m/s with charge no. 1. STV Group later describes an HE-462 projectile equivalent to OF-462, showing the same round family in current export ammunition documentation.
