How Dangerous is an Over Penetrating Bullet??? (vs Human Heads)

At SHOT Show 2026, HUXWRX unveiled the new FLOW 45M suppressor, a 3D-printed titanium, modular, flow-through design. It is compatible with a wide range of calibers including .45-70, .45 ACP, 9mm, .357, .458 SOCOM, and .300 Blackout subsonic, with supersonic approval pending. The suppressor ships with a booster and thread protection ring, and is currently available.

This video highlights the overwhelming popularity and widespread use of 9mm ammunition across civilian, law enforcement, and military sectors. It warns of the significant supply chain risks associated with this over-reliance, particularly in scenarios of war escalation or widespread demand. The speaker, demonstrating significant expertise in firearm market trends and historical supply issues, strongly advises diversifying firearm calibers to mitigate potential future shortages and price spikes.

This video tests the ballistic penetration capabilities of a 100-pound lead block against various firearm calibers, from .22LR up to a .50 BMG. The test demonstrates that while smaller calibers leave minimal marks, larger rounds create significant craters. Notably, even powerful rifle rounds like the .308 and .223 fail to fully penetrate the block, highlighting lead's effectiveness as a projectile barrier. The .50 BMG is the only caliber shown to successfully penetrate the entire block and reach the target behind it.

This video from Yee Yee Life tests the ballistic resistance of steel toe boots against various firearm calibers, from .22LR up to .50 BMG. The expert instructor demonstrates that while steel toe boots can stop smaller caliber rounds like .22LR, .380 ACP, 9mm, and .45 ACP, they fail to stop higher-powered rounds such as the .44 Magnum, .50 AE, and .50 BMG, which penetrate the boots and the mannequin used for testing. The demonstration highlights the limitations of standard footwear against significant ballistic threats.

This expert analysis from GUNBROS challenges the conventional understanding of Pistol Caliber Carbines (PCCs). The instructor highlights that the core value of a PCC lies in its use of common, affordable pistol ammunition and magazines, typically 9mm. Firearms chambered in less common calibers like 5.7x28mm, especially in a carbine form factor, are critiqued for deviating from this fundamental purpose without offering commensurate benefits over established platforms like the 5.56mm AR-15.

This expert analysis debunks myths surrounding .45 ACP's 'deadliness' compared to 9mm. It emphasizes that effective handgun stopping power relies on penetration depth, bullet expansion, and crucial shot placement, rather than raw energy or caliber alone. Modern ammunition has significantly narrowed the performance gap, making shooter skill and preparation the primary determinants of effectiveness.

This video rigorously tests the self-defense capabilities of various airguns against a realistic human head ballistic target. The expert instructor demonstrates that low-power BB guns like the Daisy Red Rider offer minimal threat, while even full-auto CO2 BB guns fail to penetrate the skull. However, a high-velocity Gamo pellet rifle proves capable of causing significant damage, cracking the skull. The instructor concludes that BB guns are unsuitable for self-defense, and while pellet rifles are dangerous, they lack the immediate stopping power of conventional firearms.

This video tests the BulletSafe VP3 Level IIIA vest against various calibers up to .44 Magnum using a realistic human torso dummy. While the vest stopped all tested rounds, including a .44 Magnum and 12-gauge buckshot, significant backface deformation and blunt force trauma were evident, especially with higher-energy rounds. The dummy's shoulder blade was broken by buckshot, and severe bruising was indicated by the .44 Magnum impact.

This review of the Crosman DPMS SBR full-auto BB gun highlights its realistic AR-15 SBR aesthetics and select-fire capability. The host demonstrates its operation, including loading with a speedloader and the dual CO2 power system. Performance metrics like 1400 RPM and 430 FPS are discussed, along with its accuracy and destructive potential on targets like watermelons. The device is recommended for realistic training or plinking where live firearms are impractical.

This video tests the effectiveness and dangers of using a flare gun for self-defense. While a flare gun can ignite materials and cause internal damage to a ballistic torso, its single-shot capacity, slow reload, and high risk of starting fires make it an irresponsible and dangerous choice for defense. The test highlights the unpredictable nature and significant fire hazard associated with using flare guns in a defensive scenario.
