A shotgun barrel with a cylinder bore choke.
If you mean a choke bored barrel, it designates the amount of constriction a shotgun barrel has.
They came in various barrel lengths and choke combinations. If it is not marked on the side of the barrel, you will have to pattern the shotgun to determine the choke
Haven't seen that marking. Choke markings on Browning shotguns are coded by a series of asterisks and dashes. They also had a marking called 'ACIER SPECIAL' which simply means special steel, indicating the gun was suitable for smokeless powder.
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.
It is called "choke". lcj
Choke.
They probably denote what choke the barrel has.
No. A choke tube slips into and screws to the muzzle end of the barrel. It can only decrease the inside diameter.
