how many sheet metals it takes to stop a bullet?

This video tests the ballistic resistance of a 1kg rubber mallet against various calibers of ammunition, from .22 LR to .308 Winchester. The mallet demonstrates significant resistance, absorbing or deflecting most rounds, but is ultimately penetrated by the .308. The test highlights the surprising durability of the rubber mallet against firearm projectiles.

This video explores the terminal ballistics of 9x19mm ammunition by firing rounds into a catalog. The experiment compares a full metal jacket (FMJ) round with a lead-core bullet to a pure lead bullet with an antimony core. The results demonstrate the penetration capabilities of 9mm rounds through paper and the deformation characteristics of different bullet types upon impact with a hard surface.

This video tests the penetration capabilities of various calibers against a boulder, culminating with the .50 BMG. While smaller calibers like .22 LR, 9mm, and .45 ACP caused minimal damage, larger rounds like 5.56mm and 12 gauge slugs began to chip the rock. The .308 and initial .50 BMG shots caused significant fragmentation but did not penetrate. A second .50 BMG shot successfully penetrated the boulder.

This video demonstrates the penetration capabilities of 5.56 NATO ammunition, specifically XM193 FMJ and green tip variants, through clay media. The testing reveals that even after hitting the same point of impact as a .30-06 round, the 5.56 NATO rounds did not achieve full pass-through, with clay particles falling out from the green tip round.

This video from Regular Guy Training LLC features an expert instructor discussing the nuances of firearm reliability, particularly comparing Glock models to the Beretta 92. The instructor, with extensive experience shooting thousands of rounds through Glocks, emphasizes that while Glock has an edge in reliability under adverse conditions due to fewer moving parts, the comparison is often "splitting hairs" for critical defense, teaching, and match applications. The discussion highlights the importance of understanding stoppage frequency and clearance times for effective training.

This guide details how to clear a common 'stovepipe' malfunction on a Glock firearm, as demonstrated by an experienced instructor. The video explains that blocking the slide's rearward travel can cause this failure, leading to a 'dead trigger'. Proper clearing involves manually removing the spent casing and returning the firearm to operational status. The instructor emphasizes safe handling throughout the process.

This video features Edwin Sarkissian, an experienced firearms instructor, conducting a unique bullet penetration test. He uses 12 Ozark Trail 12-inch cast iron skillets to determine how many rounds from various calibers and firearms, including 9mm, .45 ACP, 500 S&W Magnum, 7.62x39mm, 5.56mm, 5.7x28mm, and 12 Gauge slugs, can penetrate the cookware. The results offer practical insights into the ballistic performance of different ammunition types against a common household item.

This video from Edwin Sarkissian provides an expert-level demonstration of the Serbu BFG-50A rifle's capability against a railroad track. Sarkissian, a high-level firearms enthusiast, showcases the .50 BMG caliber's power with various ammunition types, including the specialized Raufoss Mk 211 Mod 0, highlighting its penetration through thick steel. The content offers valuable insights into terminal ballistics and the performance of heavy caliber rounds.

This video demonstrates a unique application of the X Products Can Cannon, a gas-operated launcher compatible with AR-15/M16 lowers, to launch an M67-style fragmentation grenade using .223 Blanks. Expert experimentalist Edwin Sarkissian showcases the process of loading and firing the device towards a frozen lake, highlighting the launcher's ability to hold the grenade's spoon in place until firing. The demonstration results in a significant explosion and ice shatter upon impact.

This guide details a ballistic test comparing a .50 Cal Spotter round against a 1.25-inch thick bulletproof glass panel using a Serbu BFG-50A rifle. The test, conducted by firearms enthusiast Edwin Sarkissian, demonstrates the significant destructive potential of specialized .50 BMG ammunition, highlighting differences in impact effects between incendiary spotter rounds and standard FMJ rounds. The expert-level demonstration emphasizes the importance of understanding ammunition types and their performance against protective materials.
