Hodgdon CFE BLK Part 7: 150gr Supersonics

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 details a comprehensive reloading and ballistics test of Hodgdon CFE BLK powder with heavy supersonic bullets (168gr Hornady A-MAX and 175gr Sierra Match King) in 300 Blackout. The instructor, with clear expertise in reloading and ballistics, demonstrates load development across a range of charge weights, emphasizing compressed loads and their impact on performance. The testing covers both an 8.5-inch SBR and a 16-inch rifle, providing detailed group size and velocity data for each configuration and bullet weight.

This guide, presented by a Palmetto State Armory representative, demonstrates the audible and visual differences between supersonic and subsonic 300 Blackout ammunition when fired from a suppressed AR-15. It highlights that subsonic rounds eliminate the sonic crack, offering superior noise reduction for suppressed systems. The principles discussed are applicable to other calibers like 9mm.

This YouTube video focuses on firearms safety and operational knowledge, specifically warning new shooters against mixing 5.56mm and 300 Blackout ammunition in the same firearm. The title hints at potential malfunctions or dangerous situations, underscored by terms like 'explosion' and 'failure.' The inclusion of '#asmr' and '#slowmotion' suggests a focus on the visual and auditory aspects of the firearm's operation, likely highlighting the consequences of incorrect ammunition usage in a dramatic fashion. The video aims to educate novice gun owners on critical differences between common rifle calibers.

This video compares 7.62x39mm and 300 Blackout, focusing on reloading considerations and platform compatibility. The speaker, a firearms enthusiast and reloader, highlights that while 7.62x39mm may offer slightly higher velocity, 300 Blackout presents advantages for AR-15 users due to smaller rifle primers, wider bullet selection, and standard AR magazines. The diminishing availability of cheap steel-cased 7.62x39mm ammunition has narrowed the cost gap, making 300 Blackout a more appealing option for many reloaders.

This video details the process of reloading 300 Blackout ammunition using 115gr Lehigh Defense Controlled Chaos bullets. The instructor tests two powders, Alliant Power Pro 300 MP and Winchester 296, across different charge weights in both an 8.5-inch SBR and a 16-inch rifle. Comprehensive ballistics data, including velocity, standard deviation, and group sizes, is presented for each load, offering insights into optimal supersonic performance.

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.
