300 Win Mag - Berger 200.20X with H1000

This video details an experiment to achieve subsonic velocities with 300 Winchester Magnum ammunition using Hodgdon Trail Boss powder and 208-grain bullets. The instructor tests various reduced charge weights, documenting chronograph readings and impact shifts. While subsonic velocities were not achieved, the experiment highlights the challenges of loading large-case magnum cartridges for suppressed use and identifies a promising reduced-recoil load capable of stacking groups.

This video demonstrates the impact of cold temperatures on ammunition velocity. By testing Norma Oryx, Federal Power-Shok, and Remington Core-Lokt rounds after freezing, the experiment reveals significant velocity drops in standard ammunition compared to Norma's temperature-insensitive offerings. The findings highlight the importance of ammunition choice for consistent performance in extreme weather hunting scenarios.

Seth Swerczek, a former Hornady ballistician, provides expert insights into modern cartridge design, bullet technology, and practical ballistics. He explains the advantages of standardized cartridges like the 300 PRC over traditional ones like the 300 Win Mag for factory consistency and accuracy. The discussion covers bullet performance for hunting (ELD-X, CX) and precision shooting (A-TIP), along with practical advice for handloaders and considerations for short-barreled rifles.

This video demonstrates long-range precision shooting with a Ruger Precision Rifle chambered in 300 Win Mag. The shooter engages targets at 100 yards, including water bottles and steel plates, highlighting the rifle's accuracy and the importance of trigger control and recoil management. The shooter also discusses the effectiveness of the muzzle brake and the rifle's overall weight in mitigating recoil, offering insights into the experience of precision shooting.

This video from TA Targets provides an expert-level breakdown of steel target safety and design. It debunks myths about ricochets by explaining the physics of bullet fragmentation and impact on quality steel. The instructor details the three key features of a safe steel target system: quality steel plate (AR-500/AR-550), a steep forward lean angle, and movement when struck. The video also emphasizes the importance of proper mounting hardware and adherence to safe shooting distances.

This video introduces the speaker's journey into long-range shooting, driven by a desire to expand their firearms skills beyond familiar drills. They plan to attend training courses, including the Haley Strategic D5 Precision Rifle Course, and will be using a PWS 6mm ARC for training due to its low recoil and cost-effectiveness. For extreme distances, they will utilize two Bergara B14 HMR Wilderness rifles, one in 300 Win Mag and another in 300 PRC, with the latter intended for the longest ranges. The speaker emphasizes the importance of precision shooting for various applications, from hunting to self-defense, and aims to share their learning process.

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.
