Ballistics QA with Johann Boden Part 1

This video discusses a shift in handgun caliber popularity, moving away from the dominant 9mm Luger towards more powerful options like 10mm Auto and higher-velocity rounds like 5.7x28mm. The trend is driven by increased firearm availability in these calibers and a consumer desire for greater power in carry guns.

This video argues that the .45 ACP remains superior to the 9mm in terms of stopping power and impact, despite the 9mm's popularity. It details the historical development of both calibers, compares their ballistic performance, and discusses practical applications in self-defense and home defense scenarios. The .45 ACP is highlighted for its larger diameter, slower velocity, and resulting wider wound channels, especially when expansion fails.

This video details a ballistic gel test of Federal Hydra-Shok .38 Special +P 129 Grain ammunition, evaluating its performance across different handgun barrel lengths (2-inch, 3-inch, and 4-inch). The test includes chronograph readings and analysis of penetration, expansion, and tumbling within a heavy clothing barrier. The results indicate that while the ammunition achieves good penetration, it consistently fails to expand reliably, particularly from shorter barrels, suggesting a need for higher velocity for optimal performance.

This video, presented by an expert firearms instructor, explores emerging handgun calibers that are beginning to challenge 9mm's dominance. It details the ballistics, performance advantages, and specific firearm platforms for calibers like .30 Super Carry, 5.7x28mm, 10mm Auto, .357 SIG, and .22 TCM, offering insights into why shooters might choose these over the traditional 9mm for specific applications.

This video by Ted from Line 45 addresses common mistakes made by experienced firearm owners regarding safety, ammunition, zeroing, legal configurations, and practical shooting skills. It emphasizes that fundamental safety rules are paramount and should be automatic, not an afterthought. The content highlights the critical importance of understanding ballistics, legal definitions of firearms and accessories, and the distinction between static range performance and dynamic defensive shooting capabilities.

This video from Kentucky Ballistics features an expert-level penetration test comparing the 9mm and 10mm calibers. Using a Glock 19 with 124gr FMJ and a Glock 20 with 180gr FMJ, the test demonstrates that the 10mm caliber penetrates more wooden boards than the 9mm. The host, Scott, provides clear visuals and direct comparisons, showcasing safe firearm handling and structured testing methodology.

This video showcases a novel magnetic optic mount for pistols, demonstrating its quick attachment and detachment capabilities. The speaker tests its retention by racking the slide, highlighting its potential as a firearm innovation. While initially shown on a Glock, the mount is available for other platforms like Sig Sauer and HK.

This guide covers the basic operation and features of the EOTECH OGL, a compact laser aiming device. It highlights the interface controls, including the activation button and the illuminator adjustment lever, and explains the benefit of co-aligned visible and IR lasers for simplified zeroing. The use of VCSEL technology is also noted.

This entry details the innovative Full Conceal M1 system for the Sig P320 and a prototype Folding Glock 19, both designed for enhanced concealability. The M1 system, priced at $899, integrates an 18+1 capacity with a smartphone-like footprint and active retention. The Folding Glock 19 prototype showcases a unique mechanism for rapid deployment from a compact state, utilizing a 23-round 9mm magazine. Expert insights from Chris Tran (Guns & Tactics Magazine) and Mike (Full Conceal) highlight the technical aspects and practical applications of these designs.

This guide, drawing on expert instruction from UN12 Magazine, details the critical steps for properly installing and maintaining firearm sights. It emphasizes the use of witness marks on red dot sights to ensure screw security and highlights the importance of checking iron sights for mechanical integrity to prevent zero loss. Proper installation and regular checks are vital for all sighting systems.
