What marking on the barrel of a western field shotgun model 565 show what choke it has?

The choke on a Western Field shotgun model 565 is typically indicated by markings on the barrel, such as "Full," "Modified," or "Improved Cylinder." These designations inform the shooter about the constriction of the barrel's muzzle, which affects shot spread. Additionally, some shotguns may have a series of dots or other symbols to represent the choke type. Always check the owner's manual or consult a knowledgeable gunsmith for specific identification.
