Afinal, uma chave de 13mm pode ser perigosa?

This video provides an expert-level overview of various 12-gauge shotgun ammunition types, demonstrating their characteristics and effects, particularly when fired from a suppressed Mossberg 590. The instructor, with clear expertise, explains the differences in recoil, stopping power, and projectile types, ranging from standard buckshot and slugs to exotic and less-lethal loads. It's a practical guide for understanding ammunition diversity in a hypothetical survival scenario.

Ted from Line45 advises stockpiling specific ammunition calibers before anticipated shortages in 2026. He details why .22 LR, 9mm Luger, .223/5.56 NATO, 12-gauge slugs and buckshot, 7.62x39mm, and .308/7.62 NATO are critical, citing historical patterns, production limitations, and demand pressures from various user groups. The guide emphasizes maintaining separate stashes for training and defensive use across all firearm types.

This video demonstrates an experiment testing the effect of 00 Buckshot fired from an AR-style shotgun with a breacher muzzle device on an orange. The demonstration takes place at an outdoor shooting range and highlights the explosive fragmentation of the orange upon impact. The presenter, with an experienced and authoritative tone, showcases firearm handling and accessory use in a controlled environment.

This video tests the lethality of marbles as shotgun projectiles. The experiment evaluates energy, accuracy, and penetration against homemade armor. The results indicate that marbles, when fired from a shotgun, can penetrate wood and are considered lethal based on the test parameters.

This video, featuring TheYankeeMarshal, debunks the myth that birdshot is ineffective or too dangerous for home defense. The instructor explains that at close range, birdshot retains significant energy and can cause lethal damage, contrary to popular belief. He emphasizes that using birdshot for home defense to avoid harming bystanders is a dangerous misconception, as it can still be deadly.

This video compares the terminal ballistics of subsonic and supersonic .22 LR ammunition. Testing in ballistic gelatin, with and without a denim barrier, revealed that while supersonic rounds produced a larger wound channel, subsonic rounds demonstrated superior penetration, exceeding the FBI's 12-inch requirement. The instructor concludes that subsonic ammunition is not necessarily less lethal.

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.
