Chokes

On most shotguns, the diameter of the barrel at the muzzle end is constricted. This is known as the choke.

The purpose of the choke is to control the pattern of shot as it leaves the barrel. Generally, the distance at which you are shooting will determine the most suitable choke.

The choke can be either built into the barrel during manufacture or supplied as an interchangeable item that is screwed in.

There are four main choke sizes that will cover most hunting and shooting applications.

• Cylinder choke — is the same diameter as the bore. The shot pattern will spread quickly. This choke can also be used for solid slugs.

• Improved choke — allows the shot to spread fairly quickly. This choke is suitable for small game, such as rabbits and quail.

• Modified choke — is very useful for longer range shooting. The shot pattern is dense and holds the pellets closer together. This choke is very popular for most hunting situations.

• Full choke — The shot pattern holds together much longer than a modified choke and concentrates most of the pellets on the centre of the target.
