This video tests the fragmentation and lethality of various bullet impacts. While .50 BMG on wood and dirt showed minimal fragmentation, an AK-47 impacting stone caused dangerous spalling that injured a ballistic gel skull. .223 rounds hitting AR500 steel also produced spalling fragments that penetrated the gel, indicating steel targets pose the greatest risk from fragmentation.

This video from Civilian Tactical explores five distinct types of .223 Remington and 5.56 NATO ammunition. The host, demonstrating experienced firearm instruction, details the unique characteristics and intended applications of each round, including Hornady VMAX for varmint hunting, M855 'green tip' penetrators, visible tracer rounds, cost-effective steel-cased options, and Double Tap hollow points for defense. The presentation emphasizes understanding terminal ballistics and proper ammunition selection for various scenarios.

This video aims to clarify the distinctions between .223 Remington and 5.56x45mm NATO ammunition, emphasizing the critical importance of understanding these differences for rifle reliability and personal preparedness, especially in a SHTF (Shit Hits The Fan) scenario. The presenter, Sully from Line45, asserts that the differences are not mere technicalities but have practical implications for firearm function and survival.

This video tests the penetration capabilities of various calibers, from 9mm to .50 BMG, against metal water barrels filled with water. Results show that while smaller calibers are stopped by the first barrel, larger rounds like the .50 AE and .308 penetrate further. The .50 BMG successfully penetrates the first barrel and is stopped by the second, demonstrating significant stopping power.

This video demonstrates a successful method for removing a severely stuck case from an AR-10 barrel using a high-pressure grease gun and hydraulic oil. Despite a previous gunsmith's failure, the technique involving a custom adapter and specialized grease gun achieved extraction. Post-removal inspection and range testing confirmed the barrel's integrity and sub-MOA accuracy.

This video provides a comprehensive guide to reloading ammunition for the Thompson Center Compass chambered in 300 Winchester Magnum. It meticulously covers each stage of the reloading process, from an introduction and detailed discussion of components and equipment to the practical steps of brass resizing and preparation, load data analysis, setting overall length (OAL), priming, powder charging, and bullet seating. The video culminates in a range test to evaluate the reloaded ammunition, followed by a brass inspection and group review, and concludes with future plans. The content is highly educational for anyone looking to start reloading this specific caliber and rifle.

The Vortex Diamondback Tactical 6-24x50 offers excellent value for its $400 price point, featuring First Focal Plane (FFP) capability and a usable EBR-2C reticle. While it shows some chromatic aberration and has slightly mushy turrets compared to higher-end models, its tracking accuracy is comparable to the more expensive Strike Eagle. It's a strong contender for budget-conscious long-range shooters, though FFP might be less ideal for hunting than SFP.

This video explores the experimental firing of .22 airgun pellets using .22 caliber nail gun blanks, achieving velocities over 2200 fps with Level 4 loads. Despite some pellet instability at 50 yards, accuracy remained surprisingly tight, demonstrating the potential for this unconventional projectile method. The host emphasizes proper muzzle-loading technique for rifling engagement and uses a chronograph for precise data collection.
