Copper "Extreme" Penetration Bullets: Do They REALLY Work?

This review tests the Underwood 9mm 90gr Xtreme Defender, comparing it against Federal HST. The Xtreme Defender, especially the +P+ load, demonstrated significantly deeper penetration (21.5 inches) and a wider permanent wound cavity (2 inches) in ballistic gel compared to the HST. Testing through heavy clothing and barriers showed minimal impact on penetration, with the solid copper bullet retaining its effectiveness.

This video showcases a gel test and barrier test of Lehigh Defense's 9mm self-defense ammunition, featuring their Maximum Expansion, Xtreme Defense, and Controlled Fracture bullet designs. The video highlights the terminal performance and wound channel characteristics of each projectile, with a particular focus on urban environments. It also provides historical context for Lehigh Defense, mentioning its 15-year history and the recent acquisition by Bill Wilson, who aims to replicate the success of Wilson Combat. Various tests are demonstrated, including water tank and bag tests, denim testing, and a hog test, all intended to prove the effectiveness of these bullets.

This video from Lehigh Defense and Wilson Combat features a comprehensive test of three 9mm bullet types: Maximum Expansion, Controlled Fracture, and Xtreme Defense. The content includes gel tests, barrier tests, and tests against various media like denim and water tanks. A notable segment is a "Hog Test," demonstrating terminal performance in a real-world scenario. The video highlights the expertise of Mike Cyrus, with Lehigh Defense since its inception, and the company's acquisition by Bill Wilson. It aims to prove the superior performance of Lehigh Defense bullets on the market, with a focus on self-defense applications.

This video features Bill Wilson testing the Lehigh Defense Xtreme Chaos .308 160-grain bullet. The test involves firing the bullet into ballistic gel at approximately 2400 fps and observing its terminal performance, including petal separation and base expansion. The results are discussed with gun instructors Ken Hackathorn and Paul Howe. The description highlights the Xtreme Chaos bullet's unique design for optimal ballistic performance in .308 Winchester and .30-06 Springfield calibers, retaining significant base weight.

This YouTube Shorts video showcases the terminal ballistics of Lehigh Defense's 194 Grain Maximum Expansion Sub-Sonic bullet in 300 Blackout. Fired from a 16-inch barrel with a suppressor at 1000 fps, the bullet was tested in a 20-inch FBI protocol ballistic gel block. The video highlights the bullet's unique Maximum Expansion Technology, designed to create large wound channels through hydraulic energy expansion in fluid mediums, emphasizing its effectiveness in vital zones. The description contrasts this with traditional bullet expansion methods and promotes Lehigh Defense's website for further information.

This video tests the performance of Underwood Extreme Defender and Extreme Penetrator .380 Auto ammunition, specifically the +P variants. The test involves shooting through heavy clothing into ballistic gel using a Ruger LCP Max. The core question explored is whether increased pressure leads to better defensive performance. The video emphasizes safe, controlled shooting on a private range and disclaims affiliation with retailers or manufacturers.

This video, presented by Alex C of TFBTV, identifies five of the most reliable firearms across different categories. The assessment focuses on mechanical simplicity, historical production numbers, and documented performance in demanding conditions. The chosen firearms include the Glock (handgun), Uzi (SMG), Mauser 98 (bolt-action rifle), Remington 870 (shotgun), and IWI Galil (self-loading rifle), with detailed explanations for each selection based on expert criteria.

This guide details the process of loading and firing a cap and ball revolver, emphasizing the multi-step procedure required for each shot.
