Handloading PART II Pressures and Headspace ~ GunBlue's Complete Guide

This guide details how to test propellant temperature sensitivity, a crucial factor for consistent long-range accuracy. It emphasizes using a reliable chronograph and testing ammunition across a wide temperature range, from cold to hot conditions. The process involves calculating the muzzle velocity change per degree Fahrenheit to understand how temperature fluctuations affect performance, enabling shooters to account for these variations in their ballistic solutions.

This video from Iraqveteran8888's 'Gun Gripes' series strongly advises against using 'random reloads' due to significant safety risks and potential for catastrophic firearm failure. The hosts emphasize the legal requirements for manufacturing ammunition for sale (FFL Type 06) and the inherent dangers of unknown component quality, powder charges, and storage conditions. While acknowledging the rewards of meticulous handloading for accuracy, they caution that improperly loaded ammunition can lead to dangerous pressure spikes, squib loads, and firearm damage. The video stresses the importance of understanding pressure signs and avoiding cheap, unverified ammunition.

This video details the process of cloning Mk262 ammunition using IMR 8208 XBR and Alliant AR Comp powders with 77-grain Sierra bullets. The instructor meticulously works up loads, compares Remington 7.5 and CCI No. 41 primers, and discusses pressure signs, brass longevity, and potential firearm malfunctions. The content emphasizes cautious load development and understanding individual firearm behavior.

This video demonstrates the significant impact of primer choice on reloading results. By switching from Remington Gold primers to Federal 210 primers, the presenter observed a notable increase in average velocity and a decrease in standard deviation, even with identical other load components. The test highlights how primer selection can affect accuracy and point of impact.

This video addresses lead exposure concerns for high-volume shooters, emphasizing indoor range risks and mitigation strategies. It also details proper thumb placement on handguns, particularly concerning safeties on 1911/2011 platforms, and discusses handloading practices.

This video from Ballistics Lab provides an expert-level explanation of standard deviation in ammunition performance. The instructor demonstrates how lower standard deviation in handloaded ammunition leads to tighter groups and more consistent impacts at longer distances compared to factory loads. The content highlights the practical application of ballistic data for improving shooting accuracy.

This guide, drawing on decades of experience, details how to achieve rifle accuracy. It covers defining accuracy standards, understanding MOA, troubleshooting mechanical issues like loose sights and barrel contact, and optimizing bedding and muzzle conditions. The instruction emphasizes practical application for hunters and marksmen, highlighting that modern accuracy benchmarks have evolved significantly.

This guide provides expert-level instructions for disassembling, cleaning, and maintaining the Ruger 10-22 Walnut Sporter, drawing on detailed insights from GunBlue490. It emphasizes critical steps like safely removing the action from the stock to protect the walnut finish and proper cleaning techniques to ensure long-term reliability. The instruction highlights the importance of using appropriate tools and avoiding common mistakes like over-oiling the wood stock.

This video provides a detailed guide on disassembling and cleaning a Smith & Wesson Model 25 revolver, presented by a factory-trained armorer. It emphasizes proper nomenclature, tool usage, and careful handling of internal parts to avoid damage. The guide covers removing stocks, yoke, side plate, hammer, rebound slide, and trigger, with specific instructions on reassembly and common pitfalls to avoid, such as altering trigger pull components or damaging delicate parts.

This guide, presented by an expert with over 30 years of experience and U.S. Army background, details proper firearm lubrication. It emphasizes using synthetic/CLP oils sparingly, applying only a microscopic film to prevent attracting debris. The expert recommends a silicone-treated rag for regular wipe-downs and advises against over-oiling, especially in extreme environmental conditions.
