What do the different chokes mean?

Types of Tubes A choke tube also determines to some extent the shotgun’s effective range. The tighter the constriction of the tube, the farther the range. For example, a full choke is most effective at 40 to 50 yards. An improved cylinder is most effective from 20 to 35 yards.

What do the marks on chokes mean?

The notches indicate the choke tube constriction. A lower notch count means more constriction (tighter). A higher notch count means less constriction. 1 notch = Full. 2 notches = Improved modified.

What does M stand for on a choke?

Choke tubes come in four standard sizes. These are commonly known as Cylinder Choke (C), Improved Cylinder Choke (IC), Modified Choke (M), and Full Choke (F).

What do the numbers on turkey chokes mean?

The lower the number the tighter the constriction but not always the tighter the pattern. So a .65 would be a tighter choke than a .90 right?

Which type of choke is the tightest?

full choke
The full choke is the tightest choke; it has the tightest shot pattern. This choke keeps the pellets together over a greater distance. Used it for longer shots, usually beyond 40 yards. The modified choke is not as tight as the full choke.

What is the tightest 12-gauge turkey choke?

* Hevi-shot produces the tightest patterns through chokes with constrictions of about . 675. In testing, Hevi-shot fired through a special . 675-constriction tube produced an average pattern density of 94 percent.

What is the best choke restriction for turkey hunting?

Moving to a full choke will give you a . 695 choke diameter; you’ll get more energy and a tighter pattern, allowing lethal shots out to 35-40 yards. Moving to an extra-full choke pushes your limit even farther. A lot of birds are killed by hunters at 40-50 yards plus with specialty extra-full turkey chokes.

Is full choke tighter than modified?

There is also an Improved Modified choke that is slightly tighter than Modified. Full choke has tight constriction. The shot holds together even longer, making this choke good for squirrels, turkey, and other game shot at 40-yard and longer ranges.
