TRAINING AMMUNITION

PURPOSE: To reduce a carry after reaching a target of a projectile by a method wherein a liquid is sealed into a body, a seal for blocking a liquid draining hole provided at the front section is pulled to open the liquid draining hole by a spring as the velocity of a projectile body is decreased so as to suddenly decrease the velocity thereof. CONSTITUTION: A liquid 22 is sealed in the inside of a body 2 of a projectile, and a liquid draining hole 15 is formed in the front section thereof. The liquid draining hole 15 is blocked by a seal 16, and the seal 16 is pulled by a spring 19 to a specified force. When a projectile body is fired and a sabot 5 breaks up from the projectile body, the pin 15 pulls out from the seal, allowing it to move, but since the tensile force of the spring 19 is weakened by the speed reducing force applied to the projectile body at such a point in time, the seal 16 holds the liquid draining hole 15 being blocked. When the projectile flies near the target position and the velocity is decreased, the tensile force increases further, and the seal 16 is pulled to open the liquid draining hole 15, so that the projectile body becomes light, the velocity is suddenly dropped, and the range is shortened.
