How Much Firepower Can a Kevlar Helmet Really Take?

This video from Yee Yee Life tests the ballistic penetration of various firearm calibers through standard decks of playing cards. The host, demonstrating enthusiasm and proper firearm handling, shows how many decks are needed to stop rounds from 9mm up to .50 BMG. The results highlight the significant differences in power and penetration capabilities across common handgun and rifle cartridges.

In this experiment from Yee Yee Life, Parker tests the stopping power of a bowling ball against various firearm calibers, from .22 LR up to .50 BMG. While the bowling ball effectively stops handgun rounds like 9mm and .45 ACP, and even rifle rounds like 5.56 and .308, it is ultimately penetrated by the powerful .50 BMG round. The test highlights the significant difference in energy and penetration capabilities between different firearm calibers.

This video from Yee Yee Life features an experiment testing the ballistic penetration of Feastables chocolate bars against various calibers, from .22 LR to .50 BMG. The results show a clear correlation between caliber size and penetration depth, with larger calibers easily passing through dozens of bars. The host, demonstrating safe firearm handling, provides an entertaining look at projectile energy transfer.

This experiment tests the bullet-stopping power of toilet paper against various firearm calibers. Results show that common handgun rounds like 9mm and .45 ACP are stopped by 6-7 rolls, while rifle rounds require more. Higher-powered calibers like .308 Winchester and 300 Norma Magnum penetrate significantly more rolls, demonstrating the varying ballistic performance based on caliber and velocity.

This YouTube Short poses the question of whether a Stormtrooper helmet can stop a bullet. While the video's title focuses on a specific fictional item and its ballistic resistance, the core concept often involves testing common firearm calibers and their penetration capabilities against various materials. This type of content frequently overlaps with informal ballistics testing and discussions about firearm effectiveness. The short format suggests a quick, visually driven experiment or discussion.

This video tests the effectiveness of using a pillow as a makeshift silencer, a common trope in movies. The host conducts a sound test by firing a firearm into a pillow multiple times and compares the resulting sound to firing without the pillow. The visual evidence shows the pillow accumulating bullet holes, indicating it was used as a backstop.

This video tests the ballistic resistance of an excavator bucket against various calibers, from .22 LR to .50 BMG API. While smaller calibers and even .450 Bushmaster and .308 were stopped, the .50 caliber Armor Piercing Incendiary round successfully penetrated the bucket, destroying a dummy target behind it. The test highlights the significant difference in terminal effects between standard rifle rounds and specialized armor-piercing ammunition.

This video tests the penetration capabilities of various calibers against a large pine tree, culminating with a .50 BMG API round. Surprisingly, even powerful rifle rounds like 5.56mm and 7.62mm, as well as handgun rounds like 10mm and .44 Magnum, failed to fully penetrate the tree. The .50 BMG API round, while charring the entry point, also did not exit the back of the tree, demonstrating the significant stopping power of a substantial tree trunk.

This video tests the penetration capabilities of various firearms rounds in a swimming pool, from .22 LR to .50 BMG. Surprisingly, higher velocity rifle rounds like the .223 and .308 fragmented quickly, while the .50 AE Desert Eagle traveled the furthest at 190 inches. The .50 BMG sniper rifle, despite its power, only penetrated 61 inches, likely due to massive energy displacement.

This video tests the ballistic resistance of a Secret Service Suburban window against various calibers, from .22 LR to .50 BMG. While smaller calibers and even a 10mm and .44 Magnum were stopped with varying degrees of damage, the window was eventually penetrated by a .50 BMG sniper rifle round. The testing provides a clear demonstration of the limits of armored vehicle glass against high-powered rifle threats.
