| 31. | The cartridge containing propellant charge appropriate for the required range was loaded into the breech, similar to a howitzer.
|
| 32. | When the trigger is pulled, the hammer falls onto a percussion primer which ignites the black powder propellant charge.
|
| 33. | The basic propellant charges were contained in 4 small white cambric bags each containing 1 oz of guncotton yarn.
|
| 34. | The propellant charge is a ball powder with similar burning characteristics to the WC844 powder used in 5.56?5mm NATO ammunition.
|
| 35. | When the Ammonal-based propellant charge was detonated, it caused the barrel to rupture and shoot a flame wide and long.
|
| 36. | This releases the spring-loaded striker, which is flipped downwards into the percussion cap and fires the three gram propellant charge.
|
| 37. | The complete high explosive ( HE ) round consists of a fuze, the shell body, and the propellant charge assembly.
|
| 38. | Concrete blockhouses were constructed between the two gun tubes, as well as ten smaller bunkers to hold projectiles and propellant charges.
|
| 39. | As with earlier versions of the 120 mm gun, the propellant charges are loaded separately from the shell or KE projectile.
|
| 40. | For any given gun and projectile types, it reflects the distance to the target and the size of the propellant charge.
