Powder burn rates and barrel length.

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 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 video explores the complexities of high-pressure and hybrid ammunition, featuring insights from ammunition designer Jesse (Boondock Battle Station). It debunks the notion of 'easy plug-and-play' performance gains, highlighting manufacturing challenges, potential weapon system degradation, and the need for redesigned components. The discussion emphasizes that current commercial high-pressure loads offer modest velocity increases, and the true potential lies in future weapon system development for smaller platforms.

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 demonstrates the impact of barrel length on muzzle velocity using .38 Special ammunition. A 1.8-inch barrel Ruger LCR and a 6-inch barrel Ruger GP100 were tested. The results show a significant velocity difference between the two barrel lengths, highlighting how barrel length affects projectile speed.

This video provides a head-to-head accuracy test between the Ruger 10/22 and the Marlin Model 60, both chambered in .22 LR. The host, an experienced shooter, details the test methodology, including ammunition types and a consistent 25-yard range. The comparison highlights key features of each rifle, such as magazine capacity and aftermarket availability, concluding with a visual presentation of the shot groups.

This video details a comprehensive ballistics gel test for various .38 Special loads fired from a Smith & Wesson 642 snub-nose revolver. The expert instructor analyzes bullet expansion, penetration, and wound channels, offering critical insights into ammunition performance for self-defense. Key takeaways include the importance of bullet design for reliable expansion in short barrels and safety considerations for handloading .38 Special ammunition.

This guide details a head-to-head ballistic gel test comparing 9mm Luger +P and .40 S&W ammunition, as demonstrated by an experienced firearms reviewer. The test involved firing specific loads through denim barriers into gel blocks, measuring velocity and penetration, and analyzing recovered projectiles. The .40 S&W HST showed more dramatic expansion, while the 9mm +P achieved deeper penetration. The comparison highlights trade-offs between terminal performance, capacity, and recoil in compact firearms.

This video demonstrates the initial live fire of a .50 Beowulf AR-15 platform rifle, featuring a side-charging upper receiver and a Vortex red dot optic. The host, identified as a firearms enthusiast and content creator, showcases the loading process, firing, and the significant impact of the large caliber rounds on steel targets at an outdoor range. The demonstration highlights proficient firearm handling and range safety awareness.
