Underwood .30 Carbine Xtreme Cavitator

This YouTube video tests the performance of Berry's Hybrid 9mm hollow point ammunition, loaded by Underwood, for self-defense. The test involves shooting through heavy clothing into ballistic gel using a Canik Mete MC9 and a Glock 17. The video title suggests a "FAIL" for the ammunition, raising questions about the reliability of trusted manufacturers. It's a range test focused on ammunition performance and reliability, with affiliate links to related gear provided.

This YouTube video features a ballistic gel test and review of Underwood 9mm +P 147gr Hardcast ammunition. The description also lists various equipment used by the creator for their videos, including steel targets, cameras, editing software, shooting accessories like hearing protection and safety glasses, and reloading tools such as a scale and caliper. The video aims to provide insights into the performance of this specific ammunition load.

This video provides a direct comparison of .38 Special +P, .32 H&R Magnum, and .327 Federal Magnum using personal ballistic testing with hard cast Keith-style bullets. The instructor, TheYankeeMarshal, concludes that .38 Special +P, particularly with readily available factory loads, offers superior energy and performance for self-defense compared to the .32 caliber options when round counts are equal.

This video provides an expert-level ballistic gel test of Underwood Xtreme Defender 9mm ammunition, specifically the 68-grain +P and 90-grain +P+ variants. The host, demonstrating high authority through detailed analysis and professional equipment, evaluates their terminal performance fired from an HK SP5 with an 8.9-inch barrel. The test highlights extreme velocities and deep penetration, offering valuable data for self-defense ammunition selection.

This video provides an expert-level review of the Fulton Armory M1 Carbine, highlighting its potential as a modern Personal Defense Weapon (PDW). Garand Thumb details how modern accessories like suppressors, optics (Aimpoint T2 on Ultimak rail), and lights (Surefire 6P) can be integrated. The review covers the platform's lightweight nature, the effectiveness of the .30 Carbine round for home defense, and technical aspects like barrel threading (9/16-24 TPI) and magazine reliability.

This video tests the suppressibility of the powerful 10mm cartridge using an FN 510 Tactical and a Dead Air 45 Ghost suppressor. Initial tests with full-power ammunition resulted in a catastrophic frame failure of the FN 510 due to intense recoil and accessory weight. However, the setup proved more effective and pleasant with subsonic 10mm loads, demonstrating a significant reduction in noise. Ballistic gel tests compared subsonic and full-power rounds, highlighting the 10mm's significant terminal ballistics.

This video hilariously tests a heavily accessorized AR-15, dubbed the 'Zombie Carbine,' as a parody of excessive tactical gear. The build, based on a Smith & Wesson M&P15, weighs 23 pounds fully loaded with 270 rounds across nine magazines. It features multiple optics, lasers, lights, and is demonstrated with rapid fire, hip sniping, and Tannerite explosions.

This "ultimate AR-15 meltdown" test pushes a custom build to its limits, revealing key durability insights. The Faxon barrel ultimately burst after 830 rounds, but critical components like the Sharps SRC bolt carrier group and Geissele rail demonstrated impressive resilience under extreme stress and heat. The test highlights the AR-15 platform's robust design, even when subjected to conditions far exceeding typical operational use.

This video showcases an extreme full-auto durability test of a premium Definitive Arms VEPR AK, comparing it to a budget WASR-10. The VEPR AK demonstrated exceptional resilience, enduring 895 rounds before failure, significantly outperforming the WASR-10 and even a previously tested AR-15. The expert analysis highlights the AK platform's inherent durability and heat management characteristics, even under severe stress.

This video demonstrates the legendary durability of the AK platform by subjecting a Yugo M92 PAP to a 700-round continuous firing test. Despite extreme heat causing significant smoke and glowing metal, the firearm remained functional, showcasing Mikhail Kalashnikov's robust engineering. The test concludes with a cooling process and a tribute to the designer's legacy.
