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 video from Brownells Gun Tech™ Caleb Savant offers practical solutions for improving bolt action rifle accuracy. It addresses three common issues: loose action screws, incorrect barrel free-floating, and damage to the muzzle crown. The video provides actionable tips for each problem, emphasizing that these are relatively easy fixes that can significantly enhance a rifle's performance. It's aimed at bolt action rifle owners looking to troubleshoot and optimize their firearm's precision.

This in-depth analysis of an Anderson Manufacturing AR-15 barrel reveals significant quality control issues. Headspace was found to be short, and chamber mapping indicated constrictions causing potential extraction problems. Borescope inspection showed chrome flaking and a poorly machined muzzle crown, despite the barrel being chrome-lined.

This video debunks common myths about cleaning .22 rimfire barrels, emphasizing that improper techniques, not cleaning itself, cause damage. Experts advise focusing on action cleaning for semi-autos to prevent malfunctions, while barrel cleaning is only necessary when accuracy degrades. Lead fouling is rare in modern .22 LR firearms unless the bore is pitted.

This video details the critical process of crowning and chamfering a firearm's muzzle for improved accuracy and protection. It explains how a proper muzzle crown ensures consistent bullet exit, while chamfering manages gas dynamics. The guide covers re-crowning techniques, tool selection including brass vs. steel pilots, and finishing with lapping for a superior bore exit.

This guide details the process of refinishing a rifle's muzzle crown using a lathe, a critical step for maintaining or improving rifle accuracy. Larry Potterfield from MidwayUSA demonstrates how a damaged crown can significantly degrade performance and outlines the lathe-based procedure for creating a precise 11-degree target crown. The process involves facing, rounding, cutting, and lapping the muzzle to ensure a clean exit for the projectile.

This video details the process of sporterizing a Mosin Nagant by shortening the barrel to 22 inches and removing the rear sight base. It covers essential gunsmithing techniques like precise barrel measurement, cutting with a hacksaw, squaring the muzzle with a belt sander, and achieving a professional finish using a Brownells muzzle facing tool and an 11-degree target crown cutter. The removal of the rear sight base is demonstrated using an oxy-acetylene torch to melt the silver solder.

This guide, presented by Iraqveteran8888, details essential steps for inspecting military surplus rifles in a gun shop. It emphasizes proper etiquette when handling firearms, the critical importance of the muzzle crown and rifling for accuracy, and how to assess the overall condition of metal hardware and wooden stocks to determine a rifle's value and negotiate price. The expert demonstrates how to identify potential issues like worn rifling and suggests solutions such as counter-boring.

This video demonstrates the process of crowning a rifle barrel, specifically focusing on recreating a deep radius muzzle crown as seen on "Custer's rifle." The demonstration features Larry Potterfield, founder of MidwayUSA, utilizing a specialized cutter and a metal lathe. The content is geared towards gunsmiths and firearm enthusiasts interested in barrel modifications and precision work.

The muzzle crown is a critical, often overlooked, component for rifle accuracy. Even minor damage like a burr can significantly degrade performance. Proper crowning involves precise machining, often on a lathe, to create a clean, angled surface that guides the bullet smoothly out of the barrel. Different crown styles exist, but the integrity of the inner edge is paramount.
