In firearms, a choke is a tapered constriction of a shotgun barrel's bore at the muzzle end. Chokes are almost always used with modern hunting and target shotguns, to improve performance. Their purpose is to shape the spread of the shot in order to gain better range and accuracy. Chokes are variously implemented as either screw-in replaceable chokes, selectable for particular applications, or as fixed, non-replaceable chokes, integral to the shotgun barrel. William Wellington Greener is widely credited as being the inventor of the first practical choke, as documented in his classic 1888 publication, "The Gun and its Development."

  • In firearms, a choke is a tapered constriction of a shotgun barrel's bore at the muzzle end. Chokes are almost always used with modern hunting and target shotguns, to improve performance. Their purpose is to shape the spread of the shot in order to gain better range and accuracy. Chokes are variously implemented as either screw-in replaceable chokes, selectable for particular applications, or as fixed, non-replaceable chokes, integral to the shotgun barrel. William Wellington Greener is widely credited as being the inventor of the first practical choke, as documented in his classic 1888 publication, "The Gun and its Development." Chokes may be formed at the time of manufacture either as part of the barrel, by squeezing the end of the bore down over a mandrel, or by threading the barrel and screwing in an interchangeable choke tube. Chokes may also be formed even after a barrel is manufactured by increasing the diameter of the bore inside a barrel, creating what is called a "jug choke", or by installing screw-in chokes within a barrel. However implemented, a choke typically consists of a conical section that smoothly tapers from the bore diameter down to the choke diameter, followed by a cylindrical section of the choke diameter. Briley Manufacturing, one maker of interchangeable shotgun chokes, uses a conical portion about 3 times the bore diameter in length, so that the shot is gradually squeezed down with minimal deformation. The cylindrical section is shorter, usually 0.6 to 0.75 inches (15 to 19 mm). The use of interchangeable chokes allows tuning the performance of a given combination of shotgun and shotshell to achieve a desired level of performance.
