.223 Rem - 75gr Hornady BTHP with N540 & Varmint

This video tests the ballistic resistance of a 1kg rubber mallet against various calibers of ammunition, from .22 LR to .308 Winchester. The mallet demonstrates significant resistance, absorbing or deflecting most rounds, but is ultimately penetrated by the .308. The test highlights the surprising durability of the rubber mallet against firearm projectiles.

This video demonstrates the penetration capabilities of various common firearm calibers through a stack of 1000 paper plates. It highlights how bullet energy and construction significantly affect penetration depth, with higher caliber rounds generally requiring more plates to stop. The experiment provides a visual, albeit informal, understanding of ballistic performance against a soft, uniform medium.

This video details a comprehensive reloading experiment testing 19 different powders with the 75gr Hornady BTHP bullet in .223 Remington. The instructor aims to find a cost-effective path to replicating Mark 262 clone performance, analyzing group sizes and velocities for each powder charge. Several powders, including Hodgdon H322, Vitavouri N135, and AR Comp, showed promising accuracy, with AR Comp emerging as a potential top contender for further development.

This video analyzes the cost-effectiveness of reloading ammunition in 2026, focusing on common calibers like 9mm, .223/5.56, and larger calibers such as .300 Win Mag. It details the costs of components (primers, powder, brass, bullets) and compares them to factory ammunition prices. The analysis highlights that reloading is only cost-effective for those shooting a significant volume of rounds annually (at least 1,000 per year) and who can reuse brass multiple times, with a break-even point typically occurring after 3 years for common calibers and 2 years for larger calibers, assuming initial equipment costs are already covered.

This video from Line45, hosted by Ted, outlines seven critical ammunition calibers Americans should stockpile to prepare for potential ammo shortages, referencing patterns seen in 2020 and anticipating a 2026 crunch. Ted emphasizes the importance of having sufficient defensive and training ammunition for various firearms, detailing why specific calibers disappear first during panic buying and the factors influencing supply chain disruptions. The advice is geared towards intermediate shooters and gun owners concerned with preparedness.

This video provides a practical demonstration of the Colt SP1 rifle, a classic AR-15 variant. It covers essential steps from safe handling and loading Hornady .223 ammunition into a 20-round magazine to chambering a round, engaging the safety, and live fire using the fixed A1-style iron sights. The demonstration emphasizes proper technique and safety protocols for operating this vintage firearm.

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.
