To focus the pattern of shot.
A choke is a device placed on the end of a shotgun barrel that changes the pattern of the shot as it leaves the rifle.
The TIGHTEST choke (which is smallest) is the Extra Full. The largest (no choke at all) is known as a cylinder bore.
The Choke of a shotgun is the amount of barrel restriction at the muzzle end which affects the shot pattern. A full choke will keep the spray pattern of the pellets closer together farther out than if the barrel was not restricted at the muzzle. If there is no restriction at the muzzle, the choke is said to be cylinder choke or cylinder bore.
Either a full choke,or extra full choke shotgun barrel.
the barrel is constricted at the end to make the pattern of shot flow density wider or tighter. Usually from cylinder up to full choke
It affects the spread of the shot column
There is a tool known as a choke gauge. It is a tapered length of metal that is placed in the bore, and measures the width of the muzzle. Or- shoot the shotgun, and determine how it patterns, Purpose of a choke is to to open or close a shot pattern- and proof is in what the gun does.
The choke is a way of narrowing the barrel. It is designed to keep the shot in a tighter pattern. A full choke is supposed to increase the effective range of the weapon.
Depends on the load and what the maker of the choke/shotgun say.
System of changable shotgun choke tubes made by Mossberg. Accu Choke is their brand name. A shotgun choke is a means of reducing the bore size at the muzzle of a shotgun, to produce shot patterns that spread to a greater or lesser degree.
