For ideal shot patterns when bird hunting, the following is generally true for choke tubes and lead shot:

1. Full (#1) – Tight barrel constriction; generally used for shots out to 45-50 yards
2. Improved modified (#2) – further barrel constriction; generally used for shots out to 40 yards or more
3. Modified (#3) – More barrel constriction; generally used for shots out to 30 yards or more
4. Improved Cylinder (#4)  – Little barrel constriction; generally used for shots out to 20 yards or more
5. Cylinder (#5) – No barrel constriction; generally used for close range shots under 20 yards

Note: This is only a general guide for choke selection. In most hunting situations, target ranges will vary, and a improved modified (#2) or Modified (#3) are common choices for most hunting situations.  

Understanding Chokes:

Our chokes come with a “notch” marking system.  Look at the muzzle end of the choke and see how many notches it has.  Here are the notch numbers and accompanying choke indication:

• 1 notch = Full
• 2 notches = Improved modified
• 3 notches = Modified
• 4 notches = Improved cylinder
• 5 notches = Cylinder

Other Questions and Answers about Chokes:

Q: Which chokes are recommended for slugs?
A: These chokes are recommended for slugs:

• 4 notches = Improved cylinder
• 5 notches = Cylinder

A cylinder choke is recommended for shooting rifled slugs in a smooth-bore barrel. Sabot slugs should only be shot through our fully-rifled slug barrels.

It is not safe to shoot slugs through chokes tighter than those listed here.

Q: Which chokes are recommended for steel shot?
A: These chokes are recommended for steel shot:

• 3 notches = Modified
• 4 notches = Improved cylinder
• 5 notches = Cylinder
