Underwood Extreme Defender Platinum .380ACP & 9MM 68gr Ballistic Gel Test & Review

This review tests Underwood's .380 ACP +P 90-grain XTP ammunition in a ballistic gel setup simulating self-defense scenarios. Despite initial skepticism, the ammo performed exceptionally well, with both a Ruger LCP Max and a Smith & Wesson Shield EZ achieving significant expansion and adequate penetration through a heavy clothing barrier. Recovered projectiles showed near 100% weight retention, making this load one of the best .380 defensive options tested.

This video features a ballistic gel test of Underwood .380 ACP +P self-defense ammunition. The test uses heavy clothing simulation and showcases the performance of the ammo fired from a Ruger LCP Max and a Smith & Wesson Performance Center Shield EZ pistol. The creator aims to determine if this Underwood offering is a top contender for .380 self-defense.

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 YouTube video focuses on the Springfield Armory Hellcat pistol chambered in .380 ACP, specifically featuring Underwood Extreme Defender ammunition. The content likely explores the capabilities and performance of this concealed carry firearm with a particular emphasis on the defensive ammunition load.

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 features a ballistic gel test of Underwood Hardcast .380 Auto +P ammunition. The test utilizes two popular self-defense pistols, a Ruger LCP Max and a Smith & Wesson Performance Center Shield EZ, to evaluate the effectiveness of the flat nose ammunition against heavy clothing barriers. The content focuses on the performance of the ammunition and its suitability for self-defense scenarios.

This video compares the terminal performance of five common pistol calibers (.22LR, .380 ACP, 9mm, .40 S&W, .45 ACP) by shooting watermelons. The test demonstrates a significant increase in destructive power from .22LR up to .45 ACP, with the larger calibers causing more explosive expansion and fragmentation. Specific hollow-point ammunition from Speer, Aguila, and Underwood was used, highlighting the importance of bullet construction for terminal ballistics.

Buckeye Ballistics conducted a comparative test of common pistol calibers (.22LR, .380 ACP, 9mm, .40 S&W, .45 ACP) against concrete blocks. The host, demonstrating significant firearm and ballistics knowledge, emphasized extreme safety precautions due to ricochet risks. The test revealed that while larger calibers showed more damage, none could fully penetrate the concrete block's second wall, suggesting limitations for self-defense scenarios against hardened barriers.

This Taurus TX22 review details its performance with various .22 LR ammunition. While initially reliable with CCI Mini-Mags and cycling standard velocity rounds well, it encountered malfunctions with sub-sonic and high-velocity loads. A catastrophic failure occurred due to a squib load followed by a second shot, resulting in a bulged barrel and damaged magazine.

This video compares the terminal ballistics of .22LR, .22WMR, and .17HMR rimfire cartridges using cantaloupes as targets. The .22LR showed a clean pass-through with minor damage, the .22WMR caused an explosive front-face disintegration, and the .17HMR, despite its speed, disintegrated internally with no exit. The test highlights how different rimfire rounds perform on soft tissue simulants.
