The World Must Know… How BULLETPROOF Are BULLETS???

This video tests the ballistic resistance of a fire-rated door, commonly found in hospitals and schools, against various handgun and rifle calibers. The door demonstrated surprising effectiveness, stopping .22LR, .380 ACP, 9mm, 12-gauge birdshot and buckshot, and .45 ACP with only minor deformation or penetration. However, it failed to stop the 5.7x28mm round and rifle rounds like those from an AK-47, indicating it offers significant protection against most handgun threats but is not a substitute for dedicated ballistic protection.

This video explores the growing trend of shooters replacing 9mm with alternative calibers in 2025, driven by advancements in ammunition and firearm technology. The presenter, Ted from Line 45, details the strengths of .30 Super Carry for concealed carriers seeking higher capacity in compact frames, 5.7x28mm for its flat trajectory and speed, 10mm for its significant power and barrier penetration, .357 SIG for its velocity and hard target performance, and .22 TCM for its rifle-like speed in a pistol platform. The discussion highlights how these calibers address specific needs that 9mm may not always meet, emphasizing performance, capacity, and specialized applications.

Ted from Line 45 discusses the evolving landscape of handgun calibers, highlighting how shooters are increasingly looking beyond 9mm for specific needs. The video explores 30 Super Carry for increased capacity in compacts, 5.7x28mm for flat trajectory and speed, 10mm for significant stopping power, 357 SIG for barrier penetration, and 22 TCM for rifle-like velocity in a pistol platform. The discussion emphasizes that while 9mm remains a standard, newer calibers offer solutions for specialized applications.

This video features Iraqveteran8888 conducting a comprehensive torture test of the Premier Body Armor Fortis Level 3A ballistic helmet. The helmet is subjected to various threats, including 9mm, .44 Magnum, 7.62x25mm AP, and 5.7x28mm rounds, to assess its ballistic performance and backface deformation. The review highlights the helmet's construction, adjustability, and comfort, concluding it exceeded expectations against multiple calibers.

This guide outlines a tour of key firearm manufacturer booths at SHOT Show 2025, as presented by a high-profile industry influencer. It covers observations of new and notable firearms from Heckler & Koch, Smith & Wesson, Rock Island Armory, CZ, Palmetto State Armory, and KelTec, highlighting specific models and features like the HK Slap, the S&W Bodyguard 2.0, the RIA 5.0's action, the CZ Shadow 2 Target's trigger, PSA's suppressed concepts, and the KelTec PR57's unique feeding.

This video from GUNBROS critiques the concept of a Pistol Caliber Carbine (PCC), specifically questioning the value of a 5.7x28mm variant. The speaker, demonstrating experienced authority, argues that the core purpose of a PCC is cost-effectiveness and magazine commonality, typically achieved with 9mm platforms. The video contrasts this with 5.7x28mm carbines, suggesting they offer no significant benefit over a 5.56mm AR-15 while lacking the widespread ammo and magazine availability of traditional PCCs.

This video from DemolitionRanch, hosted by Matt Carriker, explores the capabilities of high-powered, regulated air rifles like the AirForce Texan SS and Sam Yang Dragon Claw. Carriker demonstrates their impressive power, accuracy, and surprisingly quiet operation due to integrated suppressors, highlighting a legal loophole where these airguns and their suppressors are not subject to NFA regulations. The content showcases ballistics testing and comparisons, emphasizing the expert knowledge of the host in firearms and related legalities.

This video features Nicholas Irving, a former Special Operations sniper, demonstrating and discussing various high-powered firearms. Irving, author of 'Way of the Reaper,' shares insights on sniper rifles like the Barrett M107A1 and SR-25, discusses the recoil of the S&W 500 Magnum, and tests the penetration capabilities of different calibers against an engine block. The content highlights practical applications and the effectiveness of these weapons in tactical scenarios.

This video demonstrates the dangerous consequences of firing incorrect ammunition calibers in firearms. Experienced instructor Matt Carriker shows how .380 ACP in a 9mm firearm and 9mm in a .40 S&W firearm can lead to cycling failures and severe brass deformation due to improper headspacing. The experiment highlights the critical importance of using the correct ammunition for each firearm to ensure safe operation and prevent damage.

This video from DemolitionRanch, featuring firearms expert Matt Carriker, tests the ballistic resistance of Flex Tape when used as improvised body armor. The experiment involves layering Flex Tape onto cardboard and testing its effectiveness against .22 LR, 5.7x28mm (FN PS90), and 9mm (CZ Scorpion Evo 3 S1) rounds. The results demonstrate that even extensive layering of Flex Tape is insufficient to stop common firearm calibers, highlighting the importance of proper ballistic materials.
