This video compares two distinct 12-gauge shotgun rounds, the RIP and Sbrown, by testing their terminal ballistics in ballistic gelatin. Both rounds utilize different expansion mechanisms: the RIP features petals that separate upon impact, while the Sbrown has a massive hollow-point cavity designed to collapse. Despite their differing designs, both rounds create significant wound cavities and demonstrate comparable performance in terms of petal separation distance and core penetration, suggesting either could be an effective choice.

This video tests the 'Twister' slug, a shotgun projectile featuring three lead petals designed to open upon impact. The test demonstrates its performance by shooting a five-gallon water jug, a paper target for accuracy, and ballistic gelatin for lethality. The results show significant water displacement, a clean hole on the paper target, and petal separation in the gelatin, indicating effective expansion and penetration.

This video demonstrates a comprehensive test of a novel dumbbell-shaped projectile fired from a shotgun. The testing methodology includes impact energy assessment using a 5-gallon bucket, paper target behavior analysis, and terminal ballistics evaluation in ballistic gelatin to determine lethality and wound channel characteristics. The results indicate surprising performance from the lightweight aluminum projectile.

This video demonstrates the terminal ballistics of the 12-Gauge Full Metal Kraken Slug from Civilian Tactical. Expertly presented with a focus on safety and data, the test utilizes ballistics gelatin and a water jug to showcase the slug's devastating impact and unique 8-petal expansion pattern. The demonstration highlights the effectiveness of this specialized ammunition for tactical applications.

This video tests the 'Botfly' shotgun slug, focusing on its extreme hollow point design. Testing included hydrostatic shock via water jugs, accuracy on paper targets, and expansion in ballistics gelatin. The slug demonstrated significant energy transfer and a large initial wound cavity, though it also penetrated the gelatin completely.

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 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.
