This video reviews 10 bargain firearms available at the Holt's March 2022 sealed bid auction. The presenter, an experienced firearms enthusiast, highlights a range of shotguns, rifles, and even an air rifle, discussing their condition, features, and potential value. He emphasizes the sealed bid auction format and provides insights into what makes each gun a potential bargain, from classic English box locks to more modern sporting arms and even collectible military-style firearms.

This video explores acquiring vintage side-by-side shotguns under £1000, focusing on two specific examples from a sealed bid auction. It highlights how 'undesirable' specs like sleeving or minor stock cracks can significantly reduce value, making them accessible bargains. The instructor emphasizes looking for guns with good core mechanics and potential for restoration or use despite cosmetic flaws.

This video details a steel shot test on an older English shotgun, specifically an HW Richards box lock ejector with nitro proof barrels. The test aims to assess the impact of modern steel shot cartridges on a gun not originally designed for them, addressing common concerns about barrel damage and choke suitability. The findings suggest that with appropriate cartridge selection (standard steel, not magnum), older English guns with less than half choke can potentially handle steel shot without immediate damage, though some minor barrel swelling was observed.

This video details the critical process of measuring shotgun barrel wall thickness, a key factor in determining a firearm's safety for modern proofing. Instructor Jack Rowe emphasizes a minimum acceptable thickness of 20,000ths of an inch, with 25,000ths being preferable. He also explains how to interpret proof marks, distinguishing between black powder and nitro proofing, and highlights historical practices that could lead to thinner barrels.

This video, part of the Jack Rowe Master Gunsmith Series, focuses on understanding European proof marks and measuring shotgun chokes. It details various national proof marks, including German (NICK), Belgian (PV with a lion), French (PT and crowns), and Austrian, emphasizing the importance of identifying 'Nitro Proof' or 'NP' for modern ammunition safety. The video also demonstrates the use of choke calipers and ball gauges to measure choke constriction, highlighting typical English gun configurations where the right barrel is more open than the left.
