Underwood Extreme Defender .380acp 68gr +P & Standard Pressure Ballistic Gel Test
This ballistic gel test evaluates Underwood's 68gr Extreme Defender .380 ACP ammunition in both standard and +P pressure variants, fired from a Ruger LCP Max. The fluted copper bullets demonstrated impressive performance, achieving significant penetration and permanent cavity expansion without relying on traditional hollow point expansion. Both loads exceeded FBI minimum penetration standards after passing through four layers of denim.
