This video details the critical process of adjusting trigger pulls on British side-by-side shotguns, emphasizing its impact on marksmanship. Expert gunsmith Jack Rowe demonstrates how to measure current pull weights using an RCBS gauge and then carefully modifies the sear geometry to achieve ideal target weights. The process involves partial disassembly, precise filing of sear noses, and iterative testing to ensure accuracy and safety.

This video, featuring Larry Potterfield of MidwayUSA, provides a detailed, professional guide on finishing recoil pads for firearms. It addresses the common issue of unsightly sanding marks left by disc sanders, which can appear on both factory-installed and individually fitted pads. The demonstration showcases how to use a Miles Gilbert Recoil Pad fixture and simple hand tools to achieve a clean, professional appearance. This technique is valuable for gunsmiths and firearm owners looking to enhance the aesthetics of their rifles and shotguns.

This video demonstrates the process of lengthening the chamber on an antique Parker 12-gauge shotgun from 2.5 inches to 2.75 inches to accommodate modern shells. It highlights the importance of cleaning the chamber before using a piloted reamer and applying cutting oil. The process involves carefully turning the reamer with a tap handle until the reamer's shoulder meets the rim recess, while frequently clearing metal chips.

This video details how to inspect a side-by-side shotgun for a loose rib, a common issue that can lead to costly repairs. It covers visual checks for rib alignment and solder integrity, and introduces the 'tap test' using a brass hammer to differentiate between tight and loose solder joints by sound.

This video details the 'rejoining' process for loose British side-by-side shotguns, specifically addressing the 'off the face' condition. It demonstrates how to diagnose looseness using smoke and then meticulously refit the barrels to the receiver by replacing the hinge pin with an oversized one. The process involves reaming the receiver, fitting a new pin, and carefully filing the barrel hook and breech face for a tight, precise fit.

This video details the complex re-assembly of a W. Jeffery & Son sidelock British side-by-side shotgun. It covers intricate steps like installing the top lever, safety mechanisms, cocking levers, firing pins, and the trigger group. The process emphasizes precision, the use of specialized tools for spring compression, and traditional techniques such as heat bluing striker discs.

This video showcases advanced Cowboy Action Shooting techniques demonstrated by The Lever Action Kid. It highlights rapid engagement with a lever-action rifle, followed by a high-speed transition to dual single-action revolvers. The stage concludes with efficient manual reloading of a side-by-side shotgun.

This video provides an in-depth look at the Mosin-Nagant M91/30 PU Sniper rifle, showcasing its historical significance and operational features. It details the firearm inspection, loading procedures for 7.62x54R rounds, and a live-fire demonstration. The expert handling and clear visuals highlight the rifle's characteristics and performance.

This video details the complex gunsmithing process of reboring a Winchester 1885 Low Wall rifle from a pitted .32 Rimfire to a .357 Magnum. It covers barrel removal, sending it to a specialized shop for reboring and rifling, precise chambering and crowning on a lathe, and converting the action from rimfire to centerfire. The process concludes with barrel marking and finishing.

This video details the internal mechanics and cycle of operation for the Winchester Model 12 pump-action shotgun using a cutaway model. It explains the loading process into the magazine tube, the function of the safety mechanism, and the sequence of firing, extraction, and chambering. The demonstration highlights the hammerless design and the interaction of key components like the extractor and ejector.
