Projétil M855 (5,56 mm) VS Colete de Aço – O Que Acontece no Impacto?

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 a detailed comparison between M855 'green tip' and M193 'ball' 5.56x45mm ammunition for realistic self-defense and SHTF scenarios. It analyzes their performance based on projectile weight, velocity, penetration, fragmentation, and barrel length, offering guidance on choosing the appropriate round for different rifle configurations and tactical considerations. The speaker, with extensive military experience, emphasizes practical application over theoretical performance.

This guide, presented by Civilian Tactical, breaks down five distinct types of .223 Remington and 5.56 NATO ammunition. It covers specialized rounds like Hornady VMAX for varmint hunting, M855 'green tip' penetrators, and Double Tap defensive hollow points. The instructor also touches on tracer rounds and the differences between steel and brass-cased ammunition, emphasizing practical applications and identification markers.

This video tests the ballistic resistance of a Premier Body Armor Level 4 plate against various calibers, including 9mm, 45-70 Government, 223 Remington, 5.56x45mm NATO (M855 Green Tip), 7.62x39mm, 308 Winchester, and the 375 H&H Magnum. The plate demonstrated impressive performance, stopping all tested rounds without significant penetration, even the 375 H&H Magnum, despite being heavily compromised by previous impacts. The presenter highlights the plate's lightweight design and its ability to minimize spalling and deformation.

This video provides an expert-level demonstration of Premier Body Armor's Level 3 Steel Core Plates undergoing rigorous ballistic testing. Miles Mortensen, demonstrating high authority, subjects the plates to multiple calibers including 7.62x39mm, .308 Winchester, and 5.56x45mm NATO M855 Green Tip. The testing reveals the plates significantly exceed their NIJ Level 3 rating, withstanding approximately 78 rounds without penetration, showcasing impressive durability and value.

This review by Daily Shooter evaluates Premier Body Armor's Ultra Thin Durus 8000 Level III steel body armor. The video details its thinness, lightweight design, and multi-curve comfort compared to AR500 armor. Extensive ballistic testing is performed with various calibers including 5.56x45mm, .308 Winchester, 7.62x39mm, and 300 Blackout, demonstrating the armor's effectiveness in stopping multiple rounds without penetration. The reviewer highlights its NIJ rating and cost-effectiveness.

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.
