PPU Blank Ammunition Features PPU manufactures these .303 BRT blank cartridges with a brass case extended and shaped similarly to a loaded round rather than a simple crimped or shortened case. This full cased design provides reliable functioning across a wide range of firearm types since the blank s dimensions closely mimic a live cartridge as it feeds and extracts. A Boxer primer ignites the blank consistently giving users dependable cycling shot after shot during training sessions or reenactments. Because these are true blanks with no projectile they are intended for use only where a correct blank firing adapter is installed on the host firearm to ensure proper semi or full automatic operation. Packaged 20 rounds to a box this ammunition suits range training historical reenactment and ceremonial applications where the sound and recoil impulse of a live round is desired without a bullet being fired downrange. PPU produces blank cartridges across many calibers applying the same full cased approach to maintain reliability across firearm types. Shooters using blanks for training should always verify their firearm is fitted with the proper adapter before firing as standard barrels are not designed for extended blank use without one. This .303 BRT blank gives historical shooters and training organizations a dependable option for realistic demonstrations.
