Barrel Harmonics Testing - Part 2

This video details an extreme accuracy challenge where participants shoot at distances up to 1000 yards. It highlights the performance of various precision rifles and cartridges, including 7 PRC, 6.5 PRC, and .308 Winchester. The competition emphasizes shooter skill in adjusting for wind and ballistics, with Nate ultimately winning the challenge and a belt buckle prize.

This video provides an in-depth analysis of rifle accuracy, challenging industry claims with extensive 20-shot group testing. The Backfire team highlights the Horizon Vandal X as the most accurate factory hunting rifle and a custom 6 Dasher as the most accurate overall. They emphasize that recoil, not price or weight, strongly correlates with accuracy, and identify top performers in various price brackets.

This video provides an expert-level overview of six top-tier long-range rifle calibers for 1000+ yard shooting in 2025. It details the ballistic performance, design advantages, and practical applications of the 6.8 Western, .300 PRC, 6.5 PRC, 7mm PRC, 6.5 Creedmoor, and .338 Lapua Magnum, offering insights into their accuracy, energy retention, and wind drift characteristics.

This video evaluates the new Barnes Harvest Collection ammunition, comparing its performance and price against premium offerings from Hornady and Nosler. The presenter tests two rifle platforms, a Bergara B14 Squared in 6.5 PRC and a Bergara Premier Competition in 6.5 Creedmoor, using a chronograph to record muzzle velocities and assessing accuracy through five-shot groups. The Barnes ammo demonstrates competitive accuracy, particularly in the 6.5 Creedmoor, at a significantly lower price point than its high-end counterparts, suggesting it could influence market pricing.

This video emphasizes the importance of statistically significant sample sizes for accurate firearm testing, advocating for 20-round groups over smaller ones to reveal true performance potential and avoid cherry-picking data. It delves into the nuances of accuracy vs. precision, discusses the impact of barrel twist rates on bullet stabilization, and compares various rifle platforms and calibers, highlighting the advantages of 6.5 Creedmoor and 300 PRC for modern long-range shooting. The discussion also touches on barrel construction, the complexities of rifle building, and the evolving landscape of precision rifle components and calibers.

This video provides an expert-level comparison of Hodgdon H4350 and IMR 4350 powders for the 6.5 Creedmoor cartridge, utilizing 143gr Hornady ELD-X bullets. The instructor, Johnny, details load development, equipment, and range testing, offering valuable insights into powder burn rates, charge weights, and resulting accuracy. The analysis highlights the subtle differences between the two powders and their impact on 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.
