Jun 21, 2017 · The wider bullet also creates a bigger cavity in whatever it passes through. “If a projectile has features that would cause it to expand upon impact,” U.S. Army engineers Donald Carlucci and Sidney Jacobson explained in the textbook Ballistics: Theory and Design of Guns and Ammunition, “it will cause greater trauma.”
In the macabre world of terminal ballistics, the study of what happens when projectiles actually strike, much can be made of over-penetration: the phenomenon of bullets passing clean through their targets. That’s a problem, because the force that continues to propel the bullet has essentially been wasted, not transferred to the target.
Ballistics engineers try to balance speed, mass, and surface area to make the most effective round possible. At The Trace, we examine what happens after bullets are sold, shot, and wound human beings. The damage is often extensive, and not just for those who die.
The .223 weighs in at 55 grains , while the .22 is usually 45 grains or smaller.
Dr. Peter Rhee is a trauma surgeon who operated on victims of the 2011 shooting at a political event in Tucson, Arizona, in which six people were killed and 13 wounded in a hail of 9mm bullets. Rhee explained that the more massive the projectile, the more severe the wound.
The .22, meanwhile, leaves the muzzle at 2,690 feet per second, and slows to 840 feet per second at 500 yards. At that long distance, the .223 will slam into its target with almost twice the speed of the .22. The .223 is carrying 335 foot-pounds of force, while the .22 carries 70 foot-pounds.
A .223 is just 55 grains. The difference can be seen with pistol rounds, as well.
