choke shotgun



noun The narrowing of the cylinder bore of a shotgun at the muzzle, which minimises the spread of shot as it leaves the barrel.

Note: Shotguns cause the messiest of firearms-related homicides and suicides. Tissue devastation increases as the distance from the muzzle to the target decreases. Choke (CK) is usually expressed as percentage of shot that falls within a 30 inch–76 cm circle at 40 yards–36.5 m; ± 70% for a full CK shotgun, ± 60% for a medium CK weapon; < 20% for a sawed-off shotgun
