Shotgun Adapters ".45ACP, 9mm, .22LR" - TheFirearmGuy

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 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 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.

This video from Summer Shoots offers expert advice for new shooters on selecting their first firearm caliber. The instructor, an experienced shooter and content creator, emphasizes that the best caliber is the one a new shooter is most comfortable with, often recommending .22 LR for its low recoil and manageability. While acknowledging 9mm's defensive capabilities, the video cautions against it for absolute beginners due to higher recoil. The importance of proper firearm fit and consistent training, including dry fire, is highlighted as more critical than the initial caliber choice.

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.
