This YouTube video, titled "SIZE MATTERS Restored Ammunition Size Comparison 20mm-106mm military surplus", focuses on a visual comparison of various large-caliber military surplus ammunition sizes, ranging from 20mm to 106mm. The title suggests a presentation of different ammunition rounds, likely highlighting their physical dimensions and potential power. The inclusion of "military surplus" and specific millimeter designations indicates a focus on historical or decommissioned ordnance, appealing to enthusiasts of military hardware and historical weaponry.

This video focuses on igniting a 20mm tracer element, highlighting the significant amount of tracer compound required for such a large projectile. The description emphasizes the scale of the 20mm cannon and its tracer rounds.

This video unboxes a 70-year-old military surplus part: the Right Breechblock Slide Plate Assembly for a 20mm M24/M3 gun. The component is found preserved in cosmoline, wrapped in aged paper, and features original ordnance markings. The presenter identifies the part using a technical diagram and highlights its excellent condition, indicating it's likely New Old Stock.

This unboxing video showcases a 60-year-old 20mm M24 firing pin and guide assembly, manufactured in December 1953. The parts, from Cline Elec Mfg Co and Buffalo Arms, Inc., are presented in excellent New Old Stock (NOS) condition, still protected by original waxy paper. The video highlights the precise mechanical fit between the firing pin and its guide, emphasizing the quality of vintage military surplus components.

This video focuses on the detailed disassembly of 20mm HARDCORE ammunition, specifically the KAE Oerlikon AutoCannon TUNGSTEN 20x128mm. The title and description emphasize the 'HARDCORE' nature of the ammo and highlight its Tungsten composition, indicating a deep dive into its construction and components. The tags suggest a strong focus on military, army, and ammunition-related content, appealing to enthusiasts interested in the technical aspects of ordnance.

This video showcases the destructive power of a 20mm round fired from a Typhon 20 rifle against pressurized oxygen and acetylene tanks. The 20mm projectile demonstrated significant penetration, causing massive explosions and sending tanks flying. Even reinforced tank bases were penetrated or had rounds embedded, highlighting the extreme ballistic capabilities of this caliber.

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.
