At the Range: DRT TerminalShock .223 Rem HP

This video provides a detailed comparison of several 5.56x45mm NATO ammunition types used by the US Navy, focusing on their terminal ballistics and penetration capabilities. The Mark 255 Mod 1, featuring a compressed copper polymer core, is highlighted for its rapid fragmentation and potential for large wound channels, while the M855A1 is noted for its extreme penetration. The M855 Green Tip and Mark 262 Mod 1 are also tested for comparison.

This video demonstrates a concrete penetration test comparing the AK-47 (7.62x39mm) and the M16A1 (5.56x45mm NATO). An experienced shooter highlights the differences in projectile impact and concrete fragmentation, with the AK-47 showing more explosive results due to its larger caliber's momentum. The demonstration emphasizes safe firearm handling and proper range setup.

This video provides an expert-level demonstration of the terminal ballistics differences between 5.56mm M193 and M855 Green Tip ammunition. The demonstration, conducted by Guns Blazing Ranch, clearly shows M855's superior penetration capability on concrete due to its steel penetrator core, contrasting with M193's more superficial impact. The Springfield Armory Saint rifle, equipped with a suppressor, is used for the live-fire tests.

This video by Ted from Line45 outlines seven essential calibers Americans should stockpile to prepare for potential ammunition shortages, citing patterns observed in past events like the 2020 crunch. The advice focuses on calibers that disappear first due to high demand from various user groups, supply chain vulnerabilities, and production limitations. The instructor emphasizes maintaining separate stashes for training and defensive ammunition for each caliber.

This video tests the ballistic resistance of a sledgehammer against various calibers, from .22 LR to .50 BMG. It demonstrates that even smaller rounds cause superficial damage, while larger calibers like 7.62x39mm and 5.56mm create significant dents and fragmentation. The .50 BMG round causes the most substantial damage, but the hammer remains intact, suggesting a high degree of ballistic resistance.

This video tests the bullet resistance of a sledgehammer against various calibers, from .22 LR to .50 BMG. The sledgehammer demonstrates significant resistance, with no caliber achieving a complete pass-through. Notably, even larger calibers like 7.62x39mm and 5.56x45mm NATO caused significant denting and bullet fragmentation, while the .50 BMG created a substantial divot. The experiment concludes that a sledgehammer is effectively bulletproof against the tested rounds.

This review provides an expert look at the Heizer Defense PS1 Pocket Shotgun, a unique single-shot firearm chambered in .410 and .45 Colt. The video highlights its durable stainless steel or titanium construction, integrated grip storage, and impressive reliability demonstrated through extensive stress testing. Manufactured in Missouri, the PS1 is positioned as a novel option for concealed carry or self-defense, with production and pricing details also discussed.

This review provides an expert look at the Gilboa Snake, a unique double-barrel AR-15 variant. The design, originating from Israel, focuses on maximizing firepower in short engagement windows. Key features include dual magazine wells, a proprietary gas piston system, and independent dual triggers for civilian compliance. The presenter, Liam Brien, demonstrates a high level of technical expertise regarding its operation and legal configurations.

This video compares the recoil of the Desert Eagle in .44 Magnum and .50 AE calibers. The .44 Mag features a new muzzle brake, while the .50 AE uses a 300-grain Speer Gold Dot. Simultaneous firing highlights the visual difference in muzzle flip and recoil impulse between the two powerful handguns.

This video provides an expert analysis of 9mm vs. .45 ACP performance using high-speed cameras. Instructors Patrick Sweeney and Jim Tarr from Guns & Ammo demonstrate how factors like bullet mass and energy affect recoil, slide cycling, and muzzle rise, concluding that 9mm generally offers superior control.
