This video critically examines the FBI's ballistic testing standards, highlighting areas for improvement. The presenter, Boondock, suggests that while the FBI sets a high bar, certain aspects like clothing simulation and steel barrier material consistency could be more realistic. The discussion also touches upon the nuances of over/under penetration, fragmentation versus expansion, and the importance of testing rounds based on their intended application and range, drawing parallels with military testing methodologies.

This comprehensive ballistic gel test, conducted by an expert with high authority, evaluates the performance of Winchester Silvertip .44 Magnum 210-grain JHP ammunition. The test utilizes a LabRadar for precise velocity measurements and compares performance from a 4-inch Taurus Tracker and an 8-inch Colt Anaconda, demonstrating significant velocity gains with the longer barrel. The results highlight excellent expansion, weight retention, and penetration depths suitable for self-defense applications.

This video conducts a ballistic gel test comparing 9mm and .327 Magnum Hornady Critical Defense ammunition. The test measures muzzle velocity, projectile expansion, weight retention, and penetration depth through a heavy clothing barrier. The .327 Magnum demonstrated higher muzzle velocity and energy, while the 9mm achieved greater penetration depth. Both rounds showed good expansion and weight retention, making them viable self-defense options.

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 presents a ballistic gel test of a Barnaul .410 3-inch slug. The test reveals impressive performance for a .410 slug, achieving significant expansion and limiting penetration to approximately 12 inches due to its mushrooming. The slug exhibited excellent weight retention, even exceeding its advertised weight, and a substantial expansion diameter.

This video tests Armscor .22WMR ammunition from both a pistol (Kel-Tec PMR30) and a rifle (Rossi RS22M) using ballistic gel. Close-range testing revealed inconsistent expansion from the pistol, with one shot showing jacket separation and minimal nose disruption, while another expanded slightly after passing through two layers of t-shirt. The rifle consistently achieved better expansion, mushrooming to approximately .30 caliber in bare gel and through four layers of denim, though the presenter suggests this expansion may not be sufficient for longer ranges.
