5.56mm - M193 vs. M855 Green tip

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 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 video debunks the widespread rumor that Glock has released an AR-15 for the general public. It clarifies that the 'Glock AR-15' refers to the GR-115 rifle, selected through a UK National Police Primary Carbine Tender. The content emphasizes that this is a procurement process, not a commercial product launch, and explains the nuances of UK procurement frameworks. It highlights the lack of official US product announcements from Glock and discusses the complexities of entering the competitive US rifle market.

This video provides a visual demonstration of terminal ballistics using a clay block as a medium. It showcases the differing effects of .22 LR, 9mm Luger, and 5.56mm NATO rounds fired from distinct firearms, including a Trailblazer Firearms LifeCard, a Canik pistol, and an AR-15 equipped with a Primary Arms optic. The expert instruction highlights the comparative damage and expansion characteristics of each caliber.

This guide details the operation of the Altor Single Shot Pistol, a budget-friendly firearm chambered in 9mm Luger. It covers the unique loading, firing, and unloading procedures, emphasizing the manual nature of its operation. The demonstration highlights safe handling practices on an outdoor range, suitable for beginners familiarizing themselves with basic firearm manipulation.

This video demonstrates the basic operation of the Trailblazer Firearms LifeCard, a unique .22LR pistol designed to fold into a credit card-sized form factor. The demonstration covers unfolding the firearm, loading a single round, firing, and then folding it for storage. It highlights the LifeCard's extreme portability and simple single-shot functionality, suitable for discreet carry or as a backup firearm.

This video demonstrates fundamental firearm reloading and operation techniques for several handguns. It showcases the unique folding mechanism of the Trailblazer Firearms LifeCard, the magazine insertion and slide release on a Bersa Thunder 380, and similar operations on a CZ P-07. The instruction comes from a practitioner with smooth weapon manipulation skills.
