Usar chumbada de pesca em espingarda: será perigoso?

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 tests the ballistic resistance of an actual helicopter blade against a wide array of calibers, from .50 BMG down to .22 LR. The host, Scott from Kentucky Ballistics, systematically fires various firearms at the blade, documenting penetration and stopping power. The results reveal that while larger calibers like .50 BMG and .416 Rigby easily penetrate the blade, smaller pistol calibers and even some rifle rounds can be stopped by certain sections, particularly the thicker base. The experiment concludes by revealing the blade is surprisingly hollow in its core structure.

This video from Mr. Madness conducts a penetration test comparing 10mm, .357 Magnum, .44 Magnum, and 12 Gauge calibers for bear defense. It includes velocity measurements using a Garmin Xero C1 Pro and tests against ballistic media and a Level IV ceramic plate. The presenter emphasizes bear spray as a primary defense.

This video provides an expert-level analysis of two specialized 7.62 NATO rounds: the M61 armor-piercing bullet and the N4-61 tear gas bullet. The host, demonstrating high expertise in ballistics, conducts rigorous testing using professional equipment, including chronographs and various barrier materials like steel, concrete, and ballistic gel. The insights cover penetration capabilities, velocity data, and the effectiveness of tear gas deployment upon impact, offering valuable information for firearms enthusiasts and professionals.

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 tests the ballistic resistance of a 24-inch adjustable wrench against various calibers, from .22 LR to .50 BMG. The wrench demonstrated significant durability, withstanding multiple impacts from intermediate rifle cartridges and even showing resistance to .308 Winchester. The .50 BMG round, however, completely destroyed the wrench's internal gearing mechanism.

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.
