Loading 300 Blk - ep 32 - Maker and Lehigh Expansion Tests

This discussion from Regular Guy Training LLC delves into the practical applications and limitations of the 300 Blackout cartridge, particularly in civilian contexts. The panel of firearms instructors and enthusiasts argues that while 300 Blackout was designed for specific military roles, its civilian utility is questionable due to reliability issues, high cost, and a lack of distinct advantages over other calibers. They emphasize that a 'fighting rifle' must be reliable, accurate, and durable, qualities they find lacking in many 300 Blackout platforms when pushed to their limits. The conversation also explores the concept of a Personal Defense Weapon (PDW) and why 300 Blackout often falls short of meeting those requirements.

This guide details the process of zeroing an optic for both supersonic and subsonic 300 Blackout ammunition, as demonstrated by Palmetto State Armory. It highlights the significant difference in point of impact (around 5 inches at 50 yards) between the two ammunition types and emphasizes the critical importance of re-zeroing your optic when switching between them for accurate shooting. The instruction stresses responsible and safe firearm handling.

This video provides an in-depth look at the .45 ACP cartridge, tracing its history from its origins in the Philippines to its modern applications. It details the cartridge's ballistics, recoil characteristics, and performance in various firearms, including the M1911, revolvers, and pistol caliber carbines. The content also explores enhanced variants like .45 Super and .460 Rowland, and discusses the ease of reloading .45 ACP ammunition.

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 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 provides an in-depth look at the .45 ACP cartridge, tracing its history from its origins in the Philippines to its modern applications. It debunks myths about its recoil, highlights its effectiveness in various firearms like the 1911 and revolvers, and explores its versatility in submachine guns, pistol caliber carbines, and even specialized loads. The content emphasizes the cartridge's balance of power and control, making it a consistent choice for close-quarters engagements.

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.
