I Loaded The World's Fastest Bullet

This video provides an in-depth look at the Colt MARS (Miniature Assault Rifle System), a Personal Defense Weapon (PDW) concept revived by Centurion Arms. Originally designed by Mike Harris to outperform 9mm submachine guns and challenge AK-47s, the MARS utilizes a unique 5.56x30mm cartridge. The review highlights its development, technical modifications to an M4 platform, and the reasons Colt initially shelved the project. Expert analysis from Chris Bartocci underscores the historical significance and technical innovation of the MARS.

This video showcases the impressive power of the Western Airguns Rattler PCP air rifle, firing H&N Baracuda Hunter pellets at an astonishing 1212 FPS. The expert shooter demonstrates extreme impact energy and explosive target destruction, validated by slow-motion analysis and chronograph readings. The content highlights advanced airgun capabilities for enthusiasts.

This video compares the .204 Ruger, .22-250 Remington, and .223 Ackley Improved in a 'Varmintgeddon' barrier test. While all excelled against water jugs and 1/4 inch steel, high-velocity varmint rounds showed limited penetration against concrete and 3/8 inch steel. Actual velocities were verified, with the .22-250's advertised speed being significantly higher than measured.

The 6.5x25mm CBJ cartridge offers significant armor-piercing capabilities, even outperforming standard rifle rounds against hardened steel. It achieves this by utilizing a small, high-velocity tungsten penetrator within a sabot, scaled down from tank ammunition technology. The cartridge is designed for easy conversion of existing 9x19mm platforms like the Glock and MP5 with just a barrel change, maintaining compatibility with standard magazines and bolts.

This YouTube video features a chronograph test of .22LR high and hyper velocity defense/game loads. The description lists various equipment used in the video, including steel targets, cameras, ballistic gelatin powder, scales, calipers, hearing protection, safety glasses, and different types of splatter targets. The video aims to provide data on the performance of these specific .22LR ammunition types, likely for defense or game hunting applications.

This video explores the 6.5-06 wildcat cartridge, a modification of the .30-06 case necked down to accept a 6.5mm bullet. The presenter demonstrates its use with a Remington 700 rifle platform, highlighting the cartridge's potential and showcasing live fire results. The review emphasizes the unique nature of this handloaded round and its performance characteristics.

This comparison tests the .50 AE Desert Eagle against the .44 Magnum in various barrier tests, including wood, steel, sand, and concrete. While both calibers showed impressive power, the .50 AE demonstrated superior performance in ballistic gel with deeper penetration and a larger wound channel. Ultimately, the video questions if the .50 AE's marginal gains justify its significantly higher cost per round compared to the versatile .44 Magnum.

This video provides a detailed comparison between .223 Remington and 5.56 NATO ammunition, demonstrating their performance differences through rigorous barrier testing. While visually identical, 5.56 NATO shows a slight advantage in velocity and energy. Crucially, 5.56 NATO exhibits superior barrier penetration against lumber and steel, whereas .223 Remington struggles. Specialized rounds like M855A1 also show enhanced performance against sand barriers.

This video tests the lethality of various 'less lethal' shotgun rounds, including rubber buckshot, bean bags, and specialized projectiles. The .410 rubber buckshot demonstrated significantly higher velocity and penetration than 12-gauge versions. Bean bag rounds proved to be the most damaging, causing substantial plywood destruction and ballistic gel displacement, leading the host to conclude they are the most lethal 'less lethal' option.

This video compares 9mm, .40 S&W, and .45 ACP through various barrier tests including lumber, sand, and concrete, alongside ballistics gel testing. While all calibers performed similarly through most barriers, the .40 S&W showed slightly better penetration and expansion in ballistics gel. The host ultimately favors 9mm due to its lower recoil and higher capacity, despite the .40 S&W's respectable performance.
