This video tests Velocias 9mm 96-grain solid copper hollowpoint defensive ammunition. The instructor evaluates its performance against a steel target, observing significant mushrooming and recovery of the projectile after a 3-inch dig. Further testing in a sand jug with a 2x6 backer shows the rounds do not penetrate the wood, indicating effective energy transfer and stopping power within this medium.

This video tests the bullet resistance of a Soviet-era hammer against various calibers of ammunition, from birdshot to .50 BMG. The hammer's head showed minimal damage from smaller calibers, with paint chips and small craters, but was significantly penetrated and damaged by larger rounds like 7.62x39mm and .308 Winchester.

This video tests the bullet resistance of a 2-lb rubber mallet against various calibers, from birdshot to .50 BMG. The mallet demonstrates surprising durability, absorbing impacts from smaller calibers without penetration. However, larger calibers like .223 Remington shatter the handle, and .308 Winchester penetrates the head. The experiment highlights the potential for unexpected stopping power in common tools.

This video tests the bullet resistance of a sledgehammer against various calibers, from .22 LR to .50 BMG. The sledgehammer demonstrates significant resistance, with no caliber achieving a complete pass-through. Notably, even larger calibers like 7.62x39mm and 5.56x45mm NATO caused significant denting and bullet fragmentation, while the .50 BMG created a substantial divot. The experiment concludes that a sledgehammer is effectively bulletproof against the tested rounds.

This video compares the terminal ballistics of a powerful 72 caliber air rifle against a 12-gauge slug. Through a series of tests involving pine trees, sand, steel plates, and ballistic gel, the video demonstrates the significant momentum and penetration capabilities of heavyweight air rifle projectiles, highlighting their potential as a quieter alternative to firearms in certain scenarios.

This video tests common household objects and vehicle components as ballistic cover against various calibers including .22 LR, 9mm, .223, 12 gauge, and 300 Blackout. The experiment uses ballistic dummies to determine if objects provide cover (stopping rounds) or concealment (not stopping rounds). Results indicate that most everyday items offer minimal to no effective cover against common firearm calibers, with only certain materials and calibers showing potential to stop rounds.

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.
