Quantos litros de água são necessários para parar uma bala?

This video demonstrates that bullets can indeed ricochet off ice, similar to how they behave on water. Using a .45 ACP pistol, the experiment shows that while shallow angles may lead to penetration, shallower angles can induce a skip or ricochet. The presence of water beneath the ice and the high-speed impact are noted as factors influencing bullet behavior. The experiment concludes with a successful ricochet off the ice, impacting a tree, highlighting the potential for unpredictable projectile paths in such conditions.

This video demonstrates a penetration test comparing 5.56 NATO ammunition (FMJ and Green Tip) against a 30-06 Springfield round. The test reveals that even after hitting the same hole as a 30-06, the 5.56 NATO rounds, including the Green Tip, did not achieve pass-through, indicating significant energy dissipation within the target material. The speaker notes the clay particles falling out after the Green Tip impact.

This video explores the limits of 12 gauge shotgun slug weight, testing slugs ranging from a standard 1 ounce to a massive 6100 grain (nearly 14 oz) projectile. The presenter, Scott from Kentucky Ballistics, demonstrates the significant increase in recoil and potential firearm stress with heavier slugs. The experiment involves testing slug penetration through various mediums like water, ballistic gel, and even body armor, while also assessing the durability of different shotguns under extreme pressure.

This video demonstrates a practical, albeit unconventional, test of bullet penetration using decks of cards against various firearm calibers, from 9mm to .50 BMG. The host, a firearms enthusiast, showcases the relative stopping power of different rounds, highlighting the significant energy required to impede even smaller projectiles. The experiment emphasizes firearm safety and provides a visual understanding of ballistic performance.

This video demonstrates the extreme danger of using modern smokeless gunpowder in a muzzleloader designed for black powder. Lead instructor Scott from Kentucky Ballistics, with expertise signaled by his specialized destructive testing, shows through a catastrophic failure that modern powders create pressures far exceeding the design limits of muzzleloaders. The experiment highlights critical firearm safety and the distinct properties of different propellant types.

This video provides expert advice on stockpiling essential ammunition calibers in anticipation of potential shortages, referencing historical patterns and supply chain vulnerabilities. Ted from Line45 emphasizes the importance of maintaining a buffer of training and defensive ammunition for key calibers like .22 LR, 9mm, .223/5.56, 12-gauge slugs/buckshot, 7.62x39mm, and .308/7.62 NATO. He advises prioritizing calibers based on common use, defensive applications, and vulnerability to market fluctuations.

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 demonstrates a dramatic comparison between the .22 LR and .50 BMG calibers using a ballistic head model. The .50 BMG, when attached to an AR-15 platform via a Raptor upper, shows vastly superior destructive power, completely obliterating the model, while the .22 LR causes only superficial damage. The host's enthusiastic and experimental approach, combined with clear technical explanations, highlights the significant energy difference between these two rounds.
