Bullets from handguns are sometimes less than 300 m/s (980 ft/s) but with modern pistol loads, they usually are slightly above 300 m/s (980 ft/s), while bullets from most modern rifles exceed 750 m/s (2,500 ft/s). One recently developed class of firearm projectiles is the hyper-velocity bullet, such cartridges are usually made for achieving ...
You suck. You’re gonna kill this guy. You call yourself a good trauma surgeon. You’re the worst. And you just plow ahead and plow ahead and plow ahead. You find what’s injured. You control it. God. Oh, you are the best. You’ve done a great job. Then you’re working. You find another injury you didn’t expect. You suck, you suck, you ...
Children are less likely to survive AR-15 wounds. The leading cause of death in children between the ages of 1 and 19 in the U.S. is gun violence, according to a recent New England Journal of ...
An early mention of "hydrostatic shock" appeared in Popular Mechanics in April 1942. [7] In the scientific literature, the first discussion of pressure waves created when a bullet hits a living target is presented by E. Harvey Newton and his research group at Princeton University in 1947: [8]
Kneecapping is a form of malicious wounding, often as torture, in which the victim is injured in the knee.The injury is typically inflicted by a low-velocity gunshot to the knee pit with a handgun.
A muzzle blast which occurs when high-pressure gases within the barrel are suddenly released and rapidly expand when the projectile exits the muzzle and the bullet-bore contact that maintained the seal is removed. A typical muzzle blast generates a shock wave with a sound pressure level (SPL) of 140 dB or louder. [1]
Expelled gunshot residue does not travel very far from the muzzle because the particles lack momentum. Depending on the type of fire arm and ammunition used, it will typically travel no farther than 3–5 feet (0.9–1.5 meters) from the muzzle of the gun.
Some bullet jackets do not extend to the front of the bullet, to aid expansion and increase lethality; these are called soft point (if the exposed lead tip is solid) or hollow point bullets (if a cavity or hole is present). Steel bullets are often plated with copper or other metals for corrosion resistance during long periods of storage.
