Ammunition
The gun fired separate loading, cased charge ammunition, with one of four possible propellant charges - the full, no. 1, no. 2 and no. 3 (the smallest). In addition to 122 mm gun shells, the A-19 could fire 122 mm howitzer shells; however because of lesser durability of those shells they could not be used with full charge.
