Será que uma porta de carro aguenta um tiro de .22LR?

This video provides a detailed comparison of several 5.56x45mm NATO ammunition types used by the US Navy, focusing on their terminal ballistics and penetration capabilities. The Mark 255 Mod 1, featuring a compressed copper polymer core, is highlighted for its rapid fragmentation and potential for large wound channels, while the M855A1 is noted for its extreme penetration. The M855 Green Tip and Mark 262 Mod 1 are also tested for comparison.

This video provides an expert-level breakdown of the best ammunition cartridges for a SHTF (Shit Hits The Fan) scenario, prioritizing self-defense, food harvesting, and penetration capabilities. The instructor, with significant experience in ballistics testing, details recommendations from .22 LR for small game to .50 BMG for extreme threats, emphasizing availability, cost, and performance against various barriers. The content is geared towards individuals preparing for societal disruptions, offering practical advice on building a resilient ammunition stockpile.

This video tests the ballistic resistance of steel-toe boots against various calibers, from .22LR up to .50 BMG. While smaller calibers like .22LR and .380 ACP were completely stopped with minimal deformation, larger calibers like 9mm and .45 ACP caused significant bulging and potential toe injury, though they were still stopped. The .44 Magnum partially penetrated the steel on one attempt, and the 50 AE and 50 BMG successfully penetrated the steel toe, rendering the boots ineffective against these high-powered rounds.

This video tests the ballistic effectiveness of various locations within a vehicle against 9mm rounds. The driver's side door proved ineffective, while the trunk, areas behind two doors (when positioned low), the passenger footwell, and the wheel well demonstrated significant protection, with no observed penetration. The findings suggest that vehicles can offer substantial ballistic protection.

This video details an experimental test to determine how many bricks are required to stop various bullet calibers, from .22 LR up to .50 BMG. The host, demonstrating familiarity with safe firearm handling and various platforms, tests handguns and rifles, showcasing the significant penetration power of larger calibers like the .50 AE and .50 BMG. The experiment provides a visual demonstration of projectile energy transfer and material resistance.

This video tests the ballistic resistance of a sledgehammer against various calibers, from .22 LR to .50 BMG. It demonstrates that even smaller rounds cause superficial damage, while larger calibers like 7.62x39mm and 5.56mm create significant dents and fragmentation. The .50 BMG round causes the most substantial damage, but the hammer remains intact, suggesting a high degree of ballistic resistance.

This video explores the compatibility of a 50 BMG cartridge with a 12 gauge flare gun. The experiment reveals that while the cartridge fits, the flare gun's mechanism cannot ignite the tough 50 BMG primers. However, it successfully fires a standard 12 gauge blank, highlighting the difference in primer hardness. The content is presented from a hobbyist perspective, focusing on experimental curiosity rather than professional instruction.

This video from Tática Civil, featuring an expert instructor, explains the dangers of firing upwards due to projectile drop and terminal velocity. It demonstrates the safe use of 9mm shot shells for controlled demonstrations, highlighting the Canik Mete MC9 Prime with a Gideon Valor red dot sight. The instructor emphasizes crucial firearm safety protocols.

This guide details an experimental test to debunk the myth that a .50 BMG round passing near a target can be lethal. Using a ballistic mannequin, cardboard indicators, and a concrete backstop, the test demonstrates that a near miss from a .50 BMG round does not impart enough shockwave or air pressure to cause fatal injury, though the projectile itself possesses immense kinetic energy as evidenced by its impact on the concrete block. The test was conducted objectively by an individual with high authority, indicated by their empirical testing methods and proper safety protocols.

This video explores the surprising functionality of a realistic toy shotgun, the M870 by Dart Armory. The presenter tests if it can chamber and cycle real 12-gauge shotgun shells, comparing its operation to a Mossberg 590. The toy shotgun successfully loads, chambers, and ejects real shells, demonstrating a high degree of realism in its mechanical operation.
