Underwood Extreme Defender .380acp 68gr +P & Standard Pressure Ballistic Gel Test

This guide details a professional ballistic gel test of Underwood Xtreme Defender 9mm ammunition, including +P and +P+ variants. The test, conducted by a Tools&Targets host with high authority, utilizes a LabRadar chronograph and an HK SP5 to measure extreme velocities and terminal performance through a clothing barrier. Key takeaways include detailed penetration depths and projectile integrity analysis, highlighting the effectiveness of these specialized rounds for self-defense scenarios.

This video details a ballistic gel test of Underwood Ammo's 9mm +P+ Extreme Defender Platinum Edition ammunition. The test evaluates velocity and penetration through a heavy clothing barrier using two different firearm barrel lengths. The instructor provides insights into the performance characteristics of solid copper fluted projectiles, comparing them to traditional expanding rounds.

This video, featuring insights from Lee Vandenbrink, analyzes firearm caliber choices beyond 9mm for long-term preparedness, ranking alternatives based on logistics, performance, and user compatibility. It highlights .380 ACP for recoil management, .45 ACP for suppressed use, .357 SIG for barrier penetration, 10mm Auto for heavy defense, .30 Super Carry for capacity, 5.7x28mm for ease of use, and .22 Long Rifle as the top choice for logistical superiority and training value. The expert emphasizes understanding each caliber's role in a comprehensive survival plan.

This video tests SinterFire Special Duty ammunition, a unique sintered (powdered) copper and tin hollow-point round, using ballistic gel and a clothing barrier. The presenter, an experienced firearms instructor, evaluates its performance in 9mm and .380 ACP, focusing on penetration, fragmentation, and velocity. While initially skeptical of its light-for-caliber nature, the results show surprisingly controlled fragmentation and significant penetration from the 9mm core, leading to a re-evaluation of its potential effectiveness.

This video from Yee Yee Life demonstrates a ballistic test on steel toe boots, firing various calibers from .22LR up to .50 BMG. The expert instructor shows how lower calibers are stopped by the boots, while higher calibers like .50 AE and .50 BMG penetrate. The test highlights the limitations of steel toe boots against powerful firearm rounds.

This video explores the physics and performance of fluted projectiles, often referred to as External Hollow Points (EHPs), comparing them to traditional hollow points. The presenter details the Venturi effect and hydraulic jump principles theorized to explain their performance without relying on expansion. Personal ballistic gel testing, following FBI barrier test protocols, is presented to demonstrate their consistency through barriers and potential for increased tissue damage.

This video from Buckeye Ballistics provides a practical, albeit unconventional, comparison of five common pistol calibers (.22LR, .380 ACP, 9mm, .40 S&W, .45 ACP) by shooting watermelons. The expert demonstrates varying levels of terminal performance, from the .22LR's significant splitting to the .45 ACP's complete watermelon fragmentation, highlighting the differences in hydraulic shock and expansion. The test utilizes specific hollow-point ammunition, including Speer Gold Dot, Aguila Super Maximum, and Underwood XTP, showcasing their effects.

This video provides a practical, safety-conscious comparison of common pistol calibers (.22LR, .380 ACP, 9mm, .40 S&W, .45 ACP) against concrete blocks. The host, demonstrating high authority and expertise, details the testing methodology and results, emphasizing the risks of ricochet. None of the tested pistol calibers fully penetrated the concrete block's second wall, suggesting their limitations for certain penetration scenarios.

This review of the Taurus TX22 .22 LR pistol details its features, including a 16+1 capacity and excellent trigger. While initial testing with CCI Mini-Mags was flawless, subsequent tests with various ammunition types revealed cycling issues and culminated in a catastrophic failure. The failure was attributed to a squib load followed by a second shot, causing a barrel bulge and ruptured casing, highlighting potential ammunition inconsistencies. The review provides a detailed look at disassembly and damage assessment.

This video from Buckeye Ballistics provides an experimental comparison of three popular rimfire calibers: .22LR, .22WMR, and .17HMR, using cantaloupes as ballistic mediums. The host, an experienced shooter, demonstrates the distinct terminal ballistics of each round, highlighting how bullet construction and velocity affect target interaction. The comparison offers practical insights into the performance differences between these rimfire cartridges on soft tissue simulants.
