This "Daily Defense" episode delves into rifle ballistics, focusing on external ballistics and their impact on AR-15 platforms without complex math or graphs. It explains how gravity, air resistance (affected by temperature, altitude, and humidity), and height over bore influence bullet trajectory. Key concepts like initial intersection, maximum ordinate, and terminal intersection are detailed. The video also touches on terminal ballistics, highlighting how bullet velocity at impact and bullet fragmentation affect wounding capability and lethality in self-defense or hunting scenarios.
This video features a ballistic gel test of Hornady's 223 Remington 55gr GMX ammunition. The test, conducted by Andrew, measures key performance metrics including impact velocity (3,270 FPS), penetration depth (21.4 inches), retained projectile weight (37.2 grains), and expansion diameter (0.407" max, 0.347" min). Additional measurements for neck and TSC are also provided. The video also includes links to the content creator's social media platforms.
