This video details the assembly of a US Army 6-inch Mk29 Target Practice Shell and showcases the M1905A2 Coast Artillery Gun at Fort Pickens. It highlights the threading of the base plug and nose cone onto the shell, providing visual evidence of markings and lot numbers. The M1905A2 gun's details, including rifling and breech markings from Watervliet Arsenal, are also presented.

This video demonstrates the live-fire capabilities of the M3A1 37mm Anti-Tank Gun. It showcases the loading procedure, aiming, and the significant impact of a live round, which penetrates two vehicles in slow motion. The footage highlights the historical weapon's power and the recoil associated with firing.

This video tests how many cast iron skillets are needed to stop various bullets, from .22 LR to 500 S&W Magnum. Most common handgun rounds like 9mm and .45 ACP are stopped by two skillets. Rifle rounds like 5.56mm and 7.62x39mm also require two to three skillets, while the powerful 500 S&W Magnum penetrates three and is stopped by the fourth. The .22 LR failed to penetrate even the first skillet.

This video tests the penetration capabilities of a .50 BMG rifle, specifically the Serbu BFG-50A, against a section of railroad track. Various .50 caliber rounds, including Raufoss Mk 211 API and silver tip API, were fired. While the rifle and ammunition demonstrated the ability to penetrate even the thickest parts of the rail (over 1.5 inches), bullet deflection and shifting upon impact with the dense steel were observed.

This video demonstrates launching an M67 fragmentation grenade using an X Products Can Cannon towards a distant frozen lake. The Can Cannon, firing .223 blanks, successfully propels the grenade, which detonates upon impact, creating a visible hole in the ice. The experiment highlights the launcher's capability for extreme projectile delivery in challenging outdoor conditions.

This video tests the destructive power of a .50 caliber spotter round against 1.25-inch thick bulletproof glass, comparing it to a standard FMJ round. The spotter round, designed to spark and flash, created a larger crater and more surface damage than the FMJ round, demonstrating its specialized impact characteristics. The Serbu BFG-50A rifle was used for both tests.
