9mm vs 10mm vs 45 ACP vs .40 S&W: Penetration Test!

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 discusses the historical shift in firearm caliber preferences, particularly the move from .45 ACP and .40 S&W towards 9mm. It emphasizes that shot placement and shooter skill are paramount, regardless of caliber. The discussion also delves into the process of customizing firearms, differentiating between essential needs and desirable wants, and considering factors like trigger pull, sights, and ergonomics.

This guide outlines 12 common range mistakes seniors wish they knew sooner, focusing on safety and technique adjustments. It covers crucial advice on hearing protection, safe firearm handling, choosing appropriate calibers and firearms, and utilizing modern optics. The instruction emphasizes adapting shooting practices to account for age-related changes like reduced grip strength and vision, promoting safer and more enjoyable range experiences.

This video demonstrates a practical, albeit unconventional, test of bullet penetration using decks of cards against various firearm calibers, from 9mm to .50 BMG. The host, a firearms enthusiast, showcases the relative stopping power of different rounds, highlighting the significant energy required to impede even smaller projectiles. The experiment emphasizes firearm safety and provides a visual understanding of ballistic performance.

This video explores the terminal ballistics of 9mm ammunition impacting a frozen lake. The experiment demonstrates that while 9mm rounds can penetrate ice, they do not typically bounce back spinning as some might expect. The test also shows that even with shallow ice, 9mm bullets can be recovered, and a 'mag dump' can effectively create an ice fishing hole.

This video analyzes the cost-effectiveness of reloading ammunition in 2026, focusing on common calibers like 9mm, .223/5.56, and larger calibers such as .300 Win Mag. It details the costs of components (primers, powder, brass, bullets) and compares them to factory ammunition prices. The analysis highlights that reloading is only cost-effective for those shooting a significant volume of rounds annually (at least 1,000 per year) and who can reuse brass multiple times, with a break-even point typically occurring after 3 years for common calibers and 2 years for larger calibers, assuming initial equipment costs are already covered.
