Será que o recuo de uma arma te empurra no gelo?

This video demonstrates a practical experiment to test if an AK-47 chambered in 7.62x39mm can generate enough recoil to push a shooter backward on an icy surface. The presenter, exhibiting experienced firearm handling, conducts the test with a Century Arms AK-47, concluding that the recoil is insufficient for significant displacement. The video also touches on basic firearm safety principles.

This video demonstrates the effects of live fire on a layer of ice, progressing from smaller calibers (.22 Magnum, .380 Auto, 9mm, .45 ACP) to a rifle caliber (7.62x39mm from an AK-47). The presenter, exhibiting experienced authority, shows how projectile impact creates craters, fractures, and causes water beneath the ice to pulse, with larger calibers and rifle rounds causing significantly more damage. The experiment highlights the varying energy transfer and penetration capabilities of different firearms when impacting a frozen surface.

This guide details the installation of WOOX Forty Seven furniture on an AK-pattern rifle, along with the mounting of a Midwest Industries M-Lok rail and STARSTRIKE optic. It covers loading KAISER 7.62x39mm ammunition, magazine insertion, and fundamental shooting techniques including cycling the action, firing, and performing quick magazine changes. The demonstration emphasizes competent firearm handling and proficient reloads from an experienced shooter.

This video from Yee Yee Life tests the ballistic resistance of a real bank door against various calibers, from .22LR up to .50 BMG. The test, conducted by an experienced individual demonstrating safe firearm handling, shows the door's effectiveness against most handgun rounds and even some rifle calibers, though it is ultimately penetrated by a .50 BMG round. The experiment uses a mannequin named Fred as a target to visualize the effects of penetration.

Instruction from Ted of Line 45 provides expert insights into building an ammunition stockpile before potential shortages. The guide details which calibers are most vulnerable, like .22 LR and 9mm, and explains the impact of supply chains and import restrictions. It emphasizes strategic stockpiling for different uses, from training to self-defense, to ensure preparedness.

This video demonstrates a concrete penetration test comparing the AK-47 (7.62x39mm) and the M16A1 (5.56x45mm NATO). An experienced shooter highlights the differences in projectile impact and concrete fragmentation, with the AK-47 showing more explosive results due to its larger caliber's momentum. The demonstration emphasizes safe firearm handling and proper range setup.

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.
