This video details the initial steps of a personal project to build a .35 Whelen hunting rifle on a World War II era Mauser action. The presenter, Caleb from Brownells, outlines the process of modifying a salvaged CZ Brno Mauser, including drilling and tapping for scope mounts, installing a pre-threaded Shilen barrel, and fitting a custom stock. The project aims to create a rifle legal for whitetail hunting in Iowa, which requires straight-wall cartridges over .35 caliber.

Mark Serbu, a gun designer, details the condition of a MAT-49 parts kit he acquired for over $2000. He discusses plans to repair a damaged barrel by pressing in pins and reaming, and addresses a bent receiver. He also notes unusual markings on the trigger group, suggesting a potential undocumented modification or variant.

This episode delves into the critical aspects of reloading ammunition for ultra-long-range (ULR) and extreme long-range (ELR) shooting. Achieving extreme precision requires meticulous attention to detail, including tight control over powder charge velocity standard deviations (ideally under 10 fps), precise bullet weight sorting, and exact bullet seating depth to manage internal case volume and pressure. Factors like bullet jump to the lands and cartridge runout are also crucial for consistent aerodynamics and accuracy at extended distances.

This guide details the 'hard fitting' process for 1911 barrels and slides as demonstrated by Les Baer Custom. It covers precise fitting of the barrel hood, bottom lugs, and chamber reaming for optimal headspace and lockup. The emphasis is on traditional gunsmithing techniques for achieving high accuracy and reliability, as explained by a master gunsmith.

This guide details the advanced gunsmithing process for converting a Remington No. 1 Rolling Block rifle from obsolete .32 Rimfire to the more common .32-20 WCF centerfire cartridge. Expert gunsmith Larry Potterfield demonstrates the precise steps, including chamber reaming, breech block modification for centerfire ignition, and fabrication of a new firing pin. The process requires specialized tools and a high level of skill, suitable for experienced gunsmiths.

This video, part 3 of a 6-part series on gunsmithing by Jack Rowe, delves into the critical aspects of bore sizing and proofing firearms. It explains the necessity of precise bore dimensions for safe and accurate firearm function, detailing the processes and standards involved in ensuring barrels can withstand proof loads. The content is aimed at advanced gunsmiths and those with a deep understanding of firearm manufacturing and metallurgy.

This comprehensive guide details the precise steps for threading and chambering a barrel for a Custer's Rolling Block rifle, as demonstrated by Larry Potterfield, Founder and CEO of MidwayUSA. The process involves meticulous measurement, lathe work for shank preparation and thread cutting, precise fitting to the receiver, and expert chamber reaming and polishing. This expert-level instruction is crucial for custom rifle builds and firearm modifications.
