ARMOR WITH LINE-X - is Linex bulletproof?

This video tests the ballistic resistance of a standard belt buckle against various calibers, including .22, 9mm, and .45 ACP. The results clearly demonstrate that the belt buckle offers no significant ballistic protection, failing to stop any of the tested rounds. The experiment debunks the myth of belt buckles providing life-saving armor in self-defense scenarios.

This video tests the ballistic resistance of a Humvee windshield against various calibers. While it withstands pistol rounds like .22, 9mm, and .45 ACP, it fails against high-powered rifle rounds (5.56mm) and shotgun slugs, demonstrating clear penetration points.

This YouTube video aims to determine if the "Stopbox Pro" is bulletproof. The content likely involves testing the durability and protective capabilities of the Stopbox Pro against gunfire, potentially from various firearms and calibers. The analysis will focus on its effectiveness as a protective device, which could be relevant for self-defense or range safety discussions.

This video from Polenar Tactical showcases an expert-level, unconventional test of a Protection Group Denmark (PGD) NIJ Level 4 ballistic plate. The test goes beyond standard NIJ protocols to evaluate the plate's performance against threats like training ammo, hand grenades, incendiary rounds, and high-caliber rifle fire, demonstrating its robust construction and limitations against extreme abuse. The instructor highlights the plate's resilience even after significant damage, offering valuable insights into real-world armor performance beyond rated specifications.

This video tests the ballistic resistance of a Stanley Quencher Tumbler. A 9mm round was fired at the stainless steel cup, creating clear entrance and exit holes but leaving the cup structurally intact. The test suggests the tumbler offers some level of projectile deflection or containment, though further testing with higher caliber rounds like 5.56 is planned.

A ballistic test reveals that a World War II era M1 helmet, while stopping a 9mm round, exhibits significant backface deformation. However, it offers no protection against a 5.56 rifle round, which easily penetrates both sides. This highlights the limitations of historical ballistic protection against modern rifle calibers.

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.
