The Cylinder Bore choke makes the widest shot spread pattern compared to other chokes such as modified, full, or improved modified chokes, as it has no constriction to control the spread of the shot.
The shotgun choke that creates the widest shot spread pattern is the Cylinder Bore. Different chokes are used for various purposes, ranging from hunting to target shooting, each with a unique constriction level to control the shot's spread.
The cylinder bore choke is essentially no choke at all – it has no constriction, so the shot disperses quickly after leaving the barrel, creating the widest pattern. This is in contrast to chokes like the modified, full, or improved modified, which have tighter constrictions to keep the shot pattern closer together for longer distances. Therefore, for shooting at close range or where a wide spread is needed, the cylinder bore choke is the ideal choice.
