What type of ammunition is designed specifically for training or noise?

Blank round ammunition is specifically designed for training purposes or to create noise without firing a projectile. This type of ammunition generates the sound of gunfire, allowing shooters to practice various aspects of firearm handling, such as drawing, aiming, and manipulating their firearms, without the risk associated with live ammunition.

Blanks are particularly valuable in training scenarios where the emphasis is on commanding technique, safety drills, or situations where actual projectiles are unnecessary or could be hazardous to the environment or participants.

Other ammunition types, while useful in different contexts, do not serve the same purpose. Hollow-point ammunition is designed for self-defense and hunting, as it expands upon impact to increase lethality. Full metal jacket ammunition is primarily used for target shooting and military applications, designed for reliable feeding and penetration. Frangible ammunition is crafted to disintegrate upon impact to reduce the risk of ricochet but is still intended to be used in shooting situations where projectiles are fired.
