A Cleaner All-Purpose Pistol Powder: Winchester AutoComp

This video tests the ballistic resistance of a parking meter against various calibers, from .22LR up to .50 BMG. It demonstrates how different ammunition types penetrate or are stopped by the meter, providing a visual comparison of terminal ballistics against a common urban object. The experiment highlights the significant increase in destructive power with larger calibers.

This video from Line45, presented by Ted, details a significant crash in ammunition prices for several popular calibers in 2025. It highlights specific calibers that are now affordable for stocking up, including 9mm Luger, 223 Remington/5.56 NATO, 22LR, 40 S&W, 7.62x39mm, 308 Winchester, 12-gauge target loads, and 5.45x39mm. The instructor emphasizes the importance of buying now before potential price increases due to tariffs or election cycles, providing current price ranges and recommended retailers for each caliber.

This video investigates the common belief that .22LR bullets 'bounce around' inside a target, causing more damage than larger calibers. Through high-speed footage of ballistic tests on pork shoulder, the presenter compares .22LR (CCI subsonic and Mini Mag) with 9mm hollow point, 5.56x45mm FMJ, and 00 buckshot. The tests suggest that while .22LR may not always exit, it doesn't exhibit significant ricocheting or tumbling behavior within the medium, unlike some larger calibers which show more energy transfer and fragmentation.

This guide details a ballistic comparison between 9mm and .45 ACP calibers at 100 yards, utilizing a LabRadar for precise velocity measurements. The analysis, presented by an instructor with high authority, highlights that .45 ACP retains more energy at distance despite lower muzzle velocity. The data demonstrates practical insights into terminal ballistics for handgun cartridges.

This video emphasizes a critical imbalance in firearm ownership: investing heavily in platforms while neglecting sufficient ammunition for training. The speaker, drawing from personal experience, advocates for a 1:1 investment ratio between a firearm's cost and its corresponding ammunition, particularly for duty handguns and fighting rifles. This approach ensures adequate resources for proficiency development, which is crucial for self-defense and preparedness.

This video features a firearms trivia game where contestants answer questions about calibers, firearm origins, and terminology. Key takeaways include the common caliber for the Glock 19 (9mm Luger), the most common shotgun caliber (gauge), the effective long-range round (308 Winchester), the origin of the AR-15 (ArmaLite), and the distinction between a clip and a magazine. The video highlights the importance of accurate firearm knowledge in a fun, competitive format.

This video details the comprehensive manufacturing process of brass rifle casings by Peterson Cartridge. It covers the transformation of raw brass cups through multiple drawing, annealing, washing, heading, trimming, and tapering stages. The process emphasizes precision, quality control through extensive automated and manual inspection, and specialized treatments like neck re-annealing and anti-tarnish coating to ensure match-grade performance.

This guide details essential brass preparation steps beyond basic decapping and sizing for improved reloading accuracy. It covers cleaning, primer pocket uniforming, neck chamfering and deburring, and neck brushing. The video emphasizes that even new brass can benefit from these processes to ensure consistent bullet seating and optimal performance. The presenter, F-class John from Ultimate Reloader, highlights chamfering and deburring as critical steps that should not be skipped, regardless of time constraints.

This video debunks the myth that solid copper bullets require extremely high velocities for effective hunting performance. Through ballistics gel testing and analysis of 7 PRC loads using Barnes TTSX and LRX bullets, Gavin Gear demonstrates excellent expansion and weight retention across a wide velocity range, including lower velocities equivalent to longer ranges. The testing highlights the versatility and effectiveness of modern monolithic copper projectiles for various hunting scenarios and legal requirements.

This video details extreme pressure testing of the 6mm ARC cartridge using both a bolt-action rifle and an AR-15 platform. The experiment pushes the limits of Alpha Munitions brass with 8208 XBR powder, achieving velocities exceeding factory specifications and even 6 Creedmoor. The testing culminates in destructive attempts using a fast-burning pistol powder in an AR-15, demonstrating the significant forces involved and the potential for catastrophic failure. The presenter, Gavin Gear, emphasizes that these tests are for research only and should not be replicated due to extreme danger.
