6.5 Creedmoor - Hotter loads with H4350 and 143gr ELD-X

This video provides an expert-level explanation of Ballistic Coefficient (BC) from a seasoned firearms instructor. It details how BC affects bullet trajectory and wind drift, emphasizing its importance for long-range accuracy (500-1000 yards). The instructor also covers factors influencing BC like bullet mass and shape, and discusses the critical interplay between BC, bullet weight, and rifle twist rate, cautioning against manufacturers overstating BC values.

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 InRangeTV explains why the 44-40 cartridge is generally not recommended for modern firearms enthusiasts, despite its historical significance. The instructor, with apparent expertise in firearms, details the practical disadvantages of 44-40, including ammunition scarcity and reloading difficulties, compared to more accessible modern alternatives like 357 Magnum/38 Special or 45 Colt. The core argument centers on the 44-40's historical advantage in sealing black powder fouling due to its stepped case design, a benefit largely negated by modern ammunition and firearm designs.

This video debunks common firearm myths with practical demonstrations. It clarifies that suppressors do not make firearms silent but significantly reduce noise and recoil. The demonstration shows heavier bullets provide more knockdown power at closer ranges, while lighter, faster bullets with better ballistic coefficients are superior for long-range accuracy. The video also illustrates that barrel length does not inherently dictate accuracy, with caliber and ammunition quality being more critical factors for certain platforms like the 350 Legend. Finally, it concludes that rifle weight (heavy vs. light barrel) has a less significant impact on accuracy than ammunition and barrel quality, especially under varying environmental conditions.

This video features competitive shooter Lena Miculek attempting various internet-famous shooting challenges. She demonstrates techniques for drills like the 'Fast Drill' and 'Bill Drill,' emphasizing accuracy and speed. The content highlights the difficulty of these challenges, even for experienced shooters, and showcases different firearm types from competition pistols to pocket-sized concealed carry options.

This guide details the process of testing reloaded .308 Winchester ammunition in semi-automatic rifles like the M14 and M1A. It covers setting up a chronograph, evaluating muzzle velocity and accuracy at various distances, and checking for pressure signs on fired brass. The testing also extends to a Century Arms CETME rifle to ensure cross-platform reliability. The speaker, an experienced reloader, emphasizes practical accuracy and safe reloading practices.

This guide details a successful method for removing a stuck cartridge case from a firearm barrel using hydraulic pressure generated by a high-pressure grease gun. The technique, demonstrated by Johnny's Reloading Bench, involves a custom adapter and motor oil to hydraulically force the case out. The video highlights the importance of proper tools and high pressure, showcasing a successful extraction that saved a valuable Krieger barrel.

Instruction from a firearms enthusiast and reloader on preparing and sizing 300 Winchester Magnum brass. The video details the challenges of reloading for this caliber, including the long throat of the Thompson Center Compass rifle and the importance of proper neck tension and shoulder bumping. It covers selecting collets, setting up sizing dies, using specialized tools for case maintenance, and determining optimal seating depths for accuracy.

This video provides an in-depth review and performance test of the Vortex Diamondback Tactical 6-24x50 rifle scope, presented by Johnny, an experienced gear reviewer. The review covers technical specifications, a practical tracking test (box test) at 100 yards, and optical quality comparisons with other Vortex models. Johnny highlights the scope's First Focal Plane (FFP) reticle and its value proposition for its price point, while also noting limitations in optical clarity compared to higher-end models.

This video provides a comprehensive guide to reloading .22-250 Remington ammunition, focusing on a Remington Model 788 with a Douglas barrel. It details component selection (brass, bullets, primers, powders), case preparation, powder charging, bullet seating, and initial range testing. The instructor emphasizes accuracy and velocity, aiming to develop loads suitable for varmint and deer hunting, while also highlighting potential challenges with certain components and the firearm's specific characteristics.
