The most open shotgun choke is the Cylinder choke. It has no constriction and allows the widest spread of shot, making it ideal for close-range shooting, home defense, and situations where a wide pattern is needed.
Shotgun Choke Types from Most Open to Tightest
- Cylinder Choke: No constriction, widest shot spread, best for close-range shooting.
- Improved Cylinder Choke: Slight constriction, still very open, good for short-range shots (~25 to 30 yards).
- Modified Choke: Moderate constriction, for medium-range shots (~30 to 40 yards).
- Full Choke: Tight constriction, dense pattern, for longer-range shots (~40 yards or more).
- Extra-Full or Turkey Chokes exist with even tighter constriction but for specialized use.
Cylinder choke is typically used for close-range shooting or home defense due to its wide and even pattern.
