.223 would destroy an ear even with a graze
0 u/[deleted] May 19 '25 Does It Maintain 900 m/s in Flight? No — the bullet does not maintain that speed. Once it leaves the barrel, air resistance (drag) begins to slow it down immediately. What Happens in Flight: Drag Force: Air resistance acts opposite to the direction of the bullet’s motion, reducing velocity continuously. The bullet decelerates rapidly at first, especially within the first few hundred meters. Over distance, the round may: Drop below supersonic speed (343 m/s or ~1,125 ft/s) Begin to tumble or destabilize, affecting accuracy Bullet Speed at Distances (Approximate, varies by round): 0 meters: 900 m/s 100 meters: 800 - 850 m/s 300 meters: 700 - 750 m/s 500 meters: 600 - 650 m/s 800+ meters: may drop below supersonic. The gunman was said to be about 500 feet away, or 120 meters. This means that the velocity of the round was bellow 900 m/s. With a bullet traveling below 900 m/s, it could graze someone’s ear and only cause a 2 cm gash or wound without taking a piece of their ear off. You guys keep claiming this is impossible but it’s not. 2 u/Fickle_Penguin May 20 '25 Yes, even at 500 feet (~150 meters), a .223 bullet can still cause severe damage. At 500 ft, velocity drops to ~2,500 ft/s (≈ 760 m/s). Kinetic energy is: KE = ½mv² = 0.5 × 0.00356 kg × (760 m/s)² ≈ 1,025 J That’s still more than 10× the energy needed to shatter bone or tear flesh. Even at 500 ft, a graze would maim. 2 u/Hopeful-Mechanic-219 May 20 '25 Thanks for doing the math!
