Determining Unknown Calibers with Cerrosafe

This guide details the comprehensive maintenance and repair of a German Drilling firearm, as demonstrated by gunsmith Mark Novak. It covers the disassembly of complex lock mechanisms, identification and resolution of firing pin issues, and the use of specialized techniques like chamber casting with Cerrosafe to determine the rifle caliber (identified as 9.3x72R). The process emphasizes meticulous cleaning and minor adjustments for successful restoration of function.

Brandon Herrera, demonstrating expert knowledge of firearms law and mechanics, explains that black powder cap-and-ball revolvers are legally classified as antique firearms and exempt from many regulations. The video details the process of loading these revolvers with loose powder, balls, and caps, and introduces cartridge conversion cylinders that allow them to fire modern cartridges like .45 Colt, while potentially retaining their antique firearm status. Safety and legal considerations are emphasized throughout.

This video details the extensive process of restoring a fire-damaged Bergman Bayard 1910/21 pistol. The guide covers initial cleaning, boiling components to remove residue, using specialized brushes and bead blasting for surface preparation, applying a rust blue finish, and reassembly. The speaker, Mark Novak, demonstrates advanced gunsmithing techniques, emphasizing the importance of proper lubrication and careful handling of antique firearm parts. The process concludes with test firing to confirm functionality.

This video, titled "The LeMat Revolver, Part 2: No More Chain Fires," is the second installment in a series focusing on the LeMat Revolver. The title specifically mentions addressing the issue of "chain fires," which is a known historical problem with some revolvers. This suggests the content will likely involve a technical discussion, potentially demonstrating solutions or explaining the mechanics behind preventing these misfires on this particular firearm. Given it's part two, it implies previous content has already established the context of the LeMat Revolver.

This guide details the conservation of an 1874 Chamelot Delvigne Officers Model firearm, distinguishing it from reconditioning. It outlines a multi-step process involving careful disassembly, degreasing with carb cleaner (with specific warnings for painted finishes and wood), a boiling water rust conversion bath, and gentle polishing with a fine wire wheel to preserve the original bluing and patina. The instructor emphasizes preserving the firearm's intrinsic value over aggressive restoration.

This video details the extensive gunsmithing work performed by Mark Novak of Anvil Gunsmithing on a 1857 Norwegian Kammerlader rifle. The restoration involved addressing significant rust, fabricating replacement parts like the nipple and front sight, repairing severe stock damage with metal reinforcement, and re-bluing the firearm. The process highlights the challenges of maintaining antique firearms, particularly those used with black powder, and the dedication required to bring them back to functional condition.

This video provides an expert-level overview of a heavily customized AR-15, nicknamed the 'Zombie Destroyer', built for a thematic zombie apocalypse scenario. The build features an extensive accessory loadout including multiple optics, lasers, and flashlights, along with a high magazine capacity. The demonstration includes rapid fire, engagement of Tannerite targets, and unique shooting techniques, showcasing the rifle's capabilities and the instructor's proficiency.

This video details an extreme AR-15 meltdown test, pushing a custom build to its limits. Expert instructor Eric demonstrates the process, highlighting component durability and failure points under sustained fire. The test concludes with a catastrophic barrel failure after 830 rounds, providing valuable insights into the platform's resilience.

This guide details the process of conducting an extreme durability test on an AK-47 variant, specifically the Definitive Arms VEPR, as demonstrated by Iraqveteran8888. The test involves sustained full-auto fire to induce critical heat failure, followed by inspection of components like the barrel and gas block. The expert assessment highlights the rifle's resilience, lasting 895 rounds before failure, and compares its performance to other platforms.

This guide details a 700-round rapid-fire stress test on a Yugo M92 PAP AK-47 variant, demonstrating the platform's legendary durability under extreme heat. Performed by Eric from Iraqveteran8888, the test highlights safe handling of overheated firearms and concludes with a tribute to Mikhail Kalashnikov's engineering legacy. The firearm successfully completed the test despite significant heat buildup.
