This video details the assembly of a 30mm APFSDS-T round, showcasing the attachment of tail fins, sabot petals, and a retaining ring before insertion into the cartridge case. It then demonstrates live fire from a Mk44 Bushmaster cannon, highlighting the projectile's high velocity, approximately five times the speed of sound. The content emphasizes the technical aspects of military-grade ammunition and its application.

This video demonstrates a long-range precision shot executed with a bolt-action rifle, highlighting the physics of sound travel. The Ordnance Channel Crew, with high authority, showcases professional gear and safety protocols like range countdowns. The demonstration involves observing a delayed sound impact from a distant explosion, illustrating ballistic principles in a practical, albeit extreme, scenario.

This video compares the acoustic differences between supersonic and subsonic ammunition. It features live fire tests at 100 yards using a .223 caliber round in an AR-15 and a .38 Special revolver. The demonstration highlights how the bullet's sonic crack can arrive before the gunshot sound with supersonic rounds (AR-15), while subsonic rounds (.38 Special) produce the gunshot sound first. The tests are conducted safely and are aimed directly at the camera.
