The .665 turkey choke is considered the best diameter choke tube for hunting turkeys. While .665 is not the tightest choke tube available, it patterns extremely tight with most turkey loads.
.665 choke tubes are popular because they can deliver tight patterns with extra full diameter and work well with most turkey ammo. They are effective past 50 yards and their extended design allows for easy removal in the field. Our favorite .665 turkey choke that can deliver dense patterns is the Patternmaster Code Black Turkey Choke.
In this guide, we’ll discuss in more detail the reasons why .665 choke tubes are popular for turkey hunting and why you should think about using one this turkey season.
What does .665 mean on a choke tube?
A .665 choke tube means it has a diameter of .665-inches. Choke tubes are measured by placing calipers on the inside edges of the choke tube to record the inner diameter to a thousandth of an inch.
A .665 choke tube size is considered extra full or “turkey”. It’s one of the tightest turkey hunting choke constrictions you can get. Effective turkey hunting chokes can put a dense pattern into a 10-inch circle at extended ranges, and the .665 choke accomplishes this very well.
.665 Choke Tubes pattern extremely tight for turkey hunting
One of the traditions of turkey hunting with a .665 choke tubes is to place as many pellets into a turkey’s head and neck as possible while avoiding pellets hitting the breast and other parts of the bird.
.665 chokes accomplish this very well as the shot column remains compact over 40 yards and is almost comparable to a slug. Due to the tightness of .665 choke patterns, aiming becomes critical. A turkey’s head measures close to 6 inches and at 50 yards is a hard target to hit.
Fiber optic shotgun sights can help with shot placement on turkeys in low light. Holographic sights such as Eotech and Aimpoint are also used for both magnification and an illuminated reticle.
SUMMARY
.655 is the diameter of the choke tube in inches. .665 chokes are similar in size to that of Extra Full. Choke tubes in .665 excel at providing dense and consistent patterns at long ranges with magnum turkey loads.
Turkey choke tubes in .665 vs .655 vs .675
The .665 choke diameter is considered the standard turkey choke size, but chokes in .655 and .675 are available for some shotgun models. JEBs chokes offers several .655 choke tubes in its Head Hunter Series.
The difference between 0.665 and .655 or .675 is nominal. You aren’t likely to see that much difference in pattern tightness shooting these three sizes through the same shotgun with the same ammo. These are all turkey choke sizes, well tighter than extra full diameter.

Is a turkey choke a full choke?
A turkey choke is not a full choke. A full choke measures 0.685” in a fixed full 12 gauge. Turkey chokes measure 0.665 in a fixed choke 12 gauge. As you can see, turkey chokes are tighter than full chokes.
However, the word “turkey” choke has become synonymous with most tight patterning choke tubes and many sizes of chokes are used for turkey hunting. Because of this, a full choke can be a turkey choke in the sense that it will be used to hunt turkeys with.
Semantics aside, if we’re discussing accepted choke tube diameters and sizing standards, a full choke is not a turkey choke.
