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 from GUNBROS explains the concept of firearm twist rate, its importance for projectile stabilization, and provides historical context comparing smoothbore muskets to rifled rifles. The speaker, demonstrating high authority, details how twist rate affects heavier or longer projectiles and contrasts the effectiveness of the Brown Bess with the American Kentucky Rifle.

This video tests the lethality and accuracy of 9mm projectiles fired from a shotgun. The experiment involves shooting these projectiles into cardboard for accuracy, a soda bottle for energy, and a "shrapnel vest" to assess penetration. Results indicate a lack of stabilization for the 9mm projectiles when fired from a shotgun, with each bullet passing sideways.

This guide details the firing procedure for the American-made Airtronics PSRL-1 RPG, as demonstrated by Ian McCollum of Forgotten Weapons. It covers the loading, firing, and post-fire analysis, emphasizing the mechanics of the booster motor, flight stabilization, and the significant backblast experienced. The instruction highlights expert handling and range safety protocols for this specific weapon system.

This video from DemolitionRanch showcases the immense power of a tank's muzzle blast, specifically a 76mm round from an M4 Sherman. The experiment demonstrates the destructive force by targeting a refrigerator and a gun safe, highlighting the physics behind projectile stabilization and the sheer energy released.

Iraqveteran8888 provides an expert-level guide on how to determine the twist rate of a rifle barrel, particularly useful for older or mystery firearms. The method involves using a cleaning rod, marker, and tape measure to calculate the distance for one full 360-degree rotation of the barrel's rifling. This information is crucial for selecting the correct projectile weight for optimal stabilization and accuracy.

This guide details a practical test comparing rifled and smooth bore shotgun barrels for slug accuracy, as demonstrated by Matt Carriker of Demolition Ranch. It covers the physics of rifling, testing methodology using 12 Gauge slugs, and analysis of results, concluding that rifled barrels generally offer improved accuracy, especially at distance, though the practical difference may be less pronounced with basic sights at closer ranges.
