What is Cartridge Headspace? ~ A Comprehensive Review

This video addresses a practical question regarding firearm maintenance and care: whether leaning a gun barrel can cause it to warp. The content aims to provide a definitive answer to this common concern among firearm owners. It delves into the physical properties of gun barrels and the forces they are subjected to during storage or handling, explaining the likelihood of such damage occurring from simple leaning. The video focuses on providing clear, evidence-based information rather than demonstrating specific firearm models or shooting techniques.

This video explores the concept of "double charging" in firearms ammunition and its potential to cause an "exploded pistol". The presenter explains that while a double charge is dangerous and should be avoided, it typically only leads to catastrophic failure when the ammunition's pressure is already at its limit or when combined with other aggravating factors. The video suggests that a correctly loaded double charge, using a propellant with the right burn rate, can generate more energy without significantly altering pressure travel, allowing the firearm's mechanics to absorb the excess energy. A link to a previous video on "Setback" is provided, along with social media links and safety disclaimers.

This video explains the 'beep' sound in Johnny Q's shooting videos, identifying it as a PACT timer. The PACT Club Timer III is demonstrated, showing how its 'Go' button initiates a three-second delay before a beep, after which it records the time of the first shot and subsequent split times. This tool is essential for shooters looking to measure and improve their performance speed.

Designing reliable semi-automatic shotguns presents unique challenges primarily due to the rimmed shotgun shell, which complicates feeding and stacking in magazines. The wide variance in ammunition energy, from light birdshot to heavy slugs, further complicates the design of gas or recoil-operated actions. Consequently, many semi-auto designs require manual adjustments, making the versatile pump-action shotgun a persistent favorite.

This video showcases demonstrator units of the AR-15/M-16 fire control group. It likely explores the internal mechanisms and functionality of these critical components, offering insights into how they operate within these iconic rifle platforms. The content is expected to appeal to gunsmiths, hobbyists, and those interested in the mechanical intricacies of firearms.

This YouTube video features a cut-away demonstration of the Thompson Center Contender, specifically chambered in .22 Magnum. The video likely explores the internal mechanics and design of this iconic firearm, offering a detailed look at how it functions. Viewers can expect to see the various components of the Contender disassembled or visualized through the cut-away design. This content would appeal to firearm enthusiasts interested in the engineering and history of versatile single-shot pistols and rifles.

Achieving rifle accuracy involves understanding subjective standards like MOA, with practical tiers ranging from functional (3-4 MOA) to varmint grade (<1.5 MOA). Key factors include mechanical checks like scope mount tightness and barrel free-floating, proper bedding, a clean muzzle crown, and matching ammunition to the rifle's twist rate. Consistent shooting technique and awareness of environmental factors like mirage are also crucial for reliable performance.

This guide details the proper disassembly, cleaning, and maintenance of the Ruger 10-22 Walnut Sporter. It emphasizes careful stock removal to prevent damage, proper lubrication techniques, and the use of specific tools for cleaning the action, bolt, and barrel. The video highlights the rifle's reliability and offers expert tips for long-term care.

This video provides a detailed guide to disassembling, inspecting, and maintaining Smith & Wesson revolvers, presented by a factory-trained armorer with extensive experience. The instruction covers fundamental care, proper lubrication, and identifying potential issues. The demonstration uses a vintage 1976 S&W Model 25 chambered in .45 Colt, showcasing factory techniques learned from S&W's production engineer. The content is designed to be comprehensive, offering a rare look into closely guarded factory methods for enthusiasts and owners looking to keep their revolvers in optimal condition.

Proper firearm lubrication focuses on protection against corrosion and reducing friction wear with a microscopic film. Modern synthetic oils and CLPs are superior to older natural oils. Over-oiling attracts debris, creating an abrasive compound that accelerates wear, making frequent cleaning more critical than heavy lubrication. In extreme environments like cold or dusty deserts, running a firearm dry may be preferable to avoid malfunctions.
