This video details the features and installation of Bobro Engineering's Precision Optic Mounts. It highlights their patented BLAC lever system, robust 6061 T6 Aluminum construction with Type 3 Hard Coat Anodizing, and various models (Standard Precision, Dual Lever, Extended, Extra Extended) designed for different scope tube sizes and rail types. The mounts are engineered for a rock-solid, repeat-to-zero performance, with specific models offering features like base extensions for non-monolithic rails and co-witness capability with iron sights.

This video from Buckeye Ballistics provides a practical, albeit unconventional, comparison of five common pistol calibers (.22LR, .380 ACP, 9mm, .40 S&W, .45 ACP) by shooting watermelons. The expert demonstrates varying levels of terminal performance, from the .22LR's significant splitting to the .45 ACP's complete watermelon fragmentation, highlighting the differences in hydraulic shock and expansion. The test utilizes specific hollow-point ammunition, including Speer Gold Dot, Aguila Super Maximum, and Underwood XTP, showcasing their effects.

This video provides a practical, safety-conscious comparison of common pistol calibers (.22LR, .380 ACP, 9mm, .40 S&W, .45 ACP) against concrete blocks. The host, demonstrating high authority and expertise, details the testing methodology and results, emphasizing the risks of ricochet. None of the tested pistol calibers fully penetrated the concrete block's second wall, suggesting their limitations for certain penetration scenarios.

This review of the Taurus TX22 .22 LR pistol details its features, including a 16+1 capacity and excellent trigger. While initial testing with CCI Mini-Mags was flawless, subsequent tests with various ammunition types revealed cycling issues and culminated in a catastrophic failure. The failure was attributed to a squib load followed by a second shot, causing a barrel bulge and ruptured casing, highlighting potential ammunition inconsistencies. The review provides a detailed look at disassembly and damage assessment.

This video from Buckeye Ballistics provides an experimental comparison of three popular rimfire calibers: .22LR, .22WMR, and .17HMR, using cantaloupes as ballistic mediums. The host, an experienced shooter, demonstrates the distinct terminal ballistics of each round, highlighting how bullet construction and velocity affect target interaction. The comparison offers practical insights into the performance differences between these rimfire cartridges on soft tissue simulants.
