| 41. | The guns used two propellant charges : a RPC / 38 fore charge and a main charge in a brass cartridge.
|
| 42. | These guns were supplied with AP shells; with enlarged propellant charges, these could be fired without significant loss in muzzle velocity.
|
| 43. | The shell itself failed to enter the barbette, but the explosion flashed into the working chamber and detonated the propellant charges inside.
|
| 44. | Although proof shots are used in the service proof of barrels before use, the vast majority are used in propellant charge design.
|
| 45. | Four propellant charges were ignited in the working chamber; the resulting fire flashed up into the turret and down to the magazine.
|
| 46. | When the mine is triggered a small propellant charge in the base launches the inner body of the mine into the air.
|
| 47. | The ammunition for the 2A46 gun is in two pieces : the projectile is loaded first, followed by a separate propellant charge.
|
| 48. | The guns were loaded with MD45 propellant charges that weighed 297 lb ( 135 kg ); these were stored in silk bags.
|
| 49. | These shells weighed 240 kg ( 529 lb ), and used the 73 kg ( 161 lb ) RPC 12 propellant charge.
|
| 50. | The projectiles and wads were then pushed down into the breech with a ramrod until they were firmly seated on the propellant charge.
