Lighter match bullets as good as heavy OTM? Sierra 69gr HPBT gel test

This video discusses the historical popularity and current relevance of the 40 Smith & Wesson cartridge. The speaker highlights its advantages in USPSA competition for achieving major power factor scoring and argues for its continued viability, citing its terminal ballistics and manageable recoil compared to 9mm. The discussion also touches on the trend of law enforcement moving away from 40 S&W to 9mm, primarily for cost reasons, and the subsequent impact on firearm manufacturing.

This video from Palmetto State Armory showcases the ballistic performance of various AAC ammunition calibers, including 5.56, 6.5 Grendel, 300 Blackout, 6.5 Creedmoor, .308, .45 ACP, and 9mm, when fired into ballistic gel blocks. The testing was conducted at 20 feet to observe penetration and expansion, with slow-motion footage providing detailed visual analysis of projectile performance. The ammunition features projectiles designed in collaboration with Hornady and Sierra, with handgun projectiles manufactured in-house by AAC.

This video details a ballistic gel test of Fort Scott Munitions .45 ACP 180-grain Tumble Upon Impact ammunition, fired from a Rock Island 5-inch 1911 and a Colt 3.5-inch compact 1911. The test measures projectile velocity and observes tumbling behavior and penetration depth in ballistic gel, noting the solid copper construction and lack of deformation.

This video features a critique of a home defense AR-15 build by former Navy SEAL Jeff Gonzales. Key takeaways include the importance of a suppressor for indoor use, the critique of an overly complex sling, and recommendations for reliable optics. The discussion highlights the trade-offs of short-barreled rifles (SBRs) for home defense and emphasizes practical gear selection over complexity.

This guide details the tool-less field stripping process for the Beretta ARX-160, as demonstrated by a Beretta factory representative. It covers the quick-release barrel, stock, trigger group, and bolt assembly, emphasizing ease of maintenance. The representative highlights the rifle's modularity and ambidextrous features, noting its current military availability with future civilian plans.

This entry details the Fostech .50 Cal Drum Magazine, designed for Barrett M107 and 82A1 rifles, featuring a 20-round capacity and billet machined aluminum construction. It also touches upon the Fostech Rader .308 rifle. The information is presented with high technical focus from a manufacturer representative.

This video from ARFCOM News details a ballistic gel test of Remington's 158gr SJHP .357 Magnum ammunition fired from a 16-inch Rossi Model M92 carbine. The test highlights how carbine-length barrels significantly enhance .357 Magnum performance, achieving velocities comparable to some .300 Blackout loads and demonstrating substantial penetration and expansion in ballistic gel. The analysis touches on terminal ballistics theories and the unique behavior of high-velocity pistol rounds fired from rifles.
