The video discusses the critical debate between bullet penetration and expansion in self-defense ammunition. The speaker, Yankee, leans towards penetration, believing it's more crucial for reaching vital organs, especially when encountering barriers like windshields or car doors. While expansion creates a larger wound channel, insufficient penetration can render it ineffective. The discussion highlights that achieving maximum of both is often not feasible, and a balance is sought, with different calibers and bullet designs offering varying trade-offs.

This video demonstrates a direct comparison between two .357 Magnum ammunition types: Soft Lead Point and Full Metal Jacket (FMJ). A test firing into a pumpkin reveals that the Soft Lead Point round causes significantly more energy transfer and destructive impact, completely obliterating the target, while the FMJ round passes through with minimal damage. The speaker highlights the substantial difference in energy transfer and recommends considering these performance variations for specific applications.

This video details a ballistic gelatin test of Winchester 9mm 147gr JHP ammunition fired from a Torque G2 pistol with a 3-inch barrel. The test evaluates bullet expansion, penetration, and weight retention through single-layer t-shirt and four-layer denim barriers. The instructor notes surprisingly good performance for a budget-friendly, heavier projectile, highlighting its effectiveness despite lower advertised velocities.

This ballistic gelatin test evaluates the Sierra 115gr 9mm JHP. The test reveals inconsistent expansion and significant penetration issues, with some rounds passing completely through a 10% ballistic gelatin block even after passing through denim and t-shirt barriers. The instructor notes that only one out of three rounds expanded through denim, and expansion was minimal. The test highlights potential limitations of this ammunition for self-defense applications requiring reliable expansion and controlled penetration.

This video tests the impact energy and penetration capabilities of bean bag rounds, a type of less-lethal shotgun ammunition. Through tests involving a water jug, peanut butter, and ballistic gelatin, the video demonstrates that while these rounds are unlikely to be fatal, they possess sufficient force to incapacitate or deter a target. The presenter notes the importance of understanding the energy transfer of such munitions.

This video provides a detailed ballistic gelatin test comparing the 5.7x28mm and .22 WMR calibers, specifically using Speer Gold Dot ammunition. The instructor emphasizes the importance of matching barrel lengths for a fair comparison, using a pistol for the 5.7x28mm and a rifle for the .22 WMR to achieve similar velocities. The test includes bare gelatin and denim-covered gelatin blocks, measuring penetration, expansion, and retained weight to assess terminal ballistics.

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.
