Crimp or Don't Crimp ~ You'll Know the Answer!

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 analyzes the cost-effectiveness of reloading ammunition in 2026, focusing on common calibers like 9mm, .223/5.56, and larger calibers such as .300 Win Mag. It details the costs of components (primers, powder, brass, bullets) and compares them to factory ammunition prices. The analysis highlights that reloading is only cost-effective for those shooting a significant volume of rounds annually (at least 1,000 per year) and who can reuse brass multiple times, with a break-even point typically occurring after 3 years for common calibers and 2 years for larger calibers, assuming initial equipment costs are already covered.

This video analyzes the cost-effectiveness of reloading ammunition in 2026, focusing on common calibers like 9mm and .223/5.56, as well as larger calibers like .300 Win Mag. It highlights that while reloading can offer savings, the initial cost of equipment and the current high price of brass, often imported from India and China, significantly impact the break-even point. The analysis suggests that reloading is most beneficial for those with a long-term shooting plan, typically breaking even after three years for common calibers and two years for larger ones, assuming brass is reused.

This guide details the process of reloading 6.5 Creedmoor cartridges, emphasizing the importance of precision and consistency. It covers essential tools like reloading manuals, presses, dies, scales, and calipers. The steps include case preparation, resizing, priming, powder charging, and bullet seating, with a focus on achieving accurate and repeatable results for improved shooting performance.

This guide details how to use the Hornady Concentricity Gauge to measure and correct bullet run-out in loaded ammunition. Instruction from an expert highlights how proper alignment ensures consistent rifling engagement, leading to improved accuracy. The process involves using the gauge's dial indicator and adjustable ram to achieve straighter bullets, with noted variations in performance depending on the rifle.

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 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.
