The Most Insane 5.56 Ever Created

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 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 demonstrates a low-cost DIY method for creating rudimentary body armor using common materials: duct tape, a fiberglass welding blanket, and two ceramic tiles. The constructed armor was tested against 9mm, .223 Remington, and 5.56x45mm green tip ammunition. While it stopped 9mm and .223 rounds, it failed to stop the 5.56 green tip rounds, showing two clean exits.

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 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 an expert-level comparison between the .44 Magnum and .50 Action Express calibers, featuring a Magnum Research Desert Eagle and a Ruger Super Redhawk. The host, demonstrating high authority, conducts a series of tests including penetration through lumber, steel, sand, and concrete, followed by ballistic gel testing with hollow-point rounds. The analysis highlights differences in muzzle energy, penetration, and wound channel, ultimately questioning the cost-to-performance ratio of the .50 AE.

This video provides an in-depth, experimental comparison between .223 Remington and 5.56x45mm NATO cartridges, utilizing a chronograph and various barrier materials. The host, demonstrating high expertise through empirical testing, reveals significant performance differences, particularly in barrier penetration, with 5.56x45mm NATO generally outperforming .223 Remington.

This video from Banana Ballistics explores the surprising lethality of "less lethal" shotgun ammunition. Through rigorous testing with ballistic gel and plywood, the host demonstrates that rounds like bean bags and high-velocity .410 rubber buckshot can cause significant damage, challenging the common perception of these rounds as entirely non-lethal. The testing highlights the importance of understanding ammunition performance beyond its intended classification.

This video provides an objective comparison of 9mm Luger, .40 S&W, and .45 ACP calibers through a series of rigorous tests including lumber, sand, concrete, and ballistics gel. The host, leveraging specialized equipment like a Garmin Xero C1 Pro chronograph and digital calipers, presents data on velocity, penetration, and expansion. While .40 S&W showed competitive performance in some tests, the analysis concludes with a preference for 9mm due to its higher capacity and lower recoil, highlighting the importance of practical considerations beyond raw ballistics.
