What Is A Shotgun Choke?
A choke is simply a tapered constriction of the gun barrel’s bore at the muzzle end. The exit end of the choke is smaller by some dimension than the actual bore of the barrel. This difference is the amount of constriction. For example if the bore of the barrel is .730 and the exit dia of the choke is .710 you have a constriction of .020. The amount of constriction for a given degree of choke will also vary between manufacturers. As a general rule for standard chokes the total range will be between .000 and .045 thousandths of an inch under bore diameter. In the case of special purpose turkey chokes it can be as much as .100 or 1/10th of an inch. The length of the choke can vary as well. Most, but not all chokes will have an overall length of between 1.5 and 4 inches. Note that many fixed choke barrels marked skeet will actually be .000 or cylinder. They can be grouped in 3 general types: • Fixed chokes – They are made as an integral part of the barrel and cannot be readily changed exce
