FBI Uniform Crime Reporting breakdown comparing handguns, rifles, edged weapons, and physical assaults.
Source context: In empirical FBI UCR records, rifles of all types (semi-auto AR platforms, lever, bolt, hunting) routinely account for <3% of annual homicides. More than 3 times as many individuals are killed with cutting instruments (knives) than with all rifles combined.

Cartridge Ballistics & Kinetic Energy Physics 5.56×45mm NATO
Analyze projectile kinetic energy across standard defense and hunting cartridges using the foot-pound physics formula: E = (Weight_grains × Velocity_fps²) / 450,436.

Select Benchmark Cartridge Preset:
| Cartridge | Typical Weight | Velocity | Energy |
|---|---|---|---|
| 5.56 NATO / .223 Rem (AR-15) | 55 gr | 3,200 fps | ~1,250 ft-lbs |
| 9mm Luger (Handgun) | 115 gr | 1,180 fps | ~355 ft-lbs |
| 7.62×39mm (Intermediate) | 123 gr | 2,360 fps | ~1,520 ft-lbs |
| .308 Win / 7.62 NATO | 165 gr | 2,600 fps | ~2,476 ft-lbs |
| .30-06 Springfield (Full Power) | 180 gr | 2,700 fps | ~2,913 ft-lbs |
Physics Note: The 5.56/.223 cartridge fired by standard AR-15s is at the low end of centerfire rifle cartridge power. Standard big-game hunting cartridges (.308 Win, .30-06) deliver 2.0x to 2.4x the muzzle kinetic energy of an AR-15 round.
