Question:
Which choke tube do I use for my shotgun?

Answer:

The choice of choke should be made in relation to the distance at which most targets are to be shot. If the game is generally shot at distances of 40 yards or more, then a tight choke (improved modified or full) is appropriate. A modified choke would give approximately the same pattern density at 35 to 40 yards, improved cylinder at 30-35 yards, and so on. Since studies have shown that the great majority of game is shot at ranges under 40 yards, the modified choke is the most generally accepted for all-around shooting conditions.

Using target loads as the control ammunition the following percentages may be expected from the following chokes:

 

DESCRIPTION PATTERN PERCENTAGE
INVECTOR DS CHOKE, 12, FULL 75-80%
INVECTOR DS CHOKE, 12, LIGHT FULL 70-75%
INVECTOR DS CHOKE, 12, IMOD 65-75%
INVECTOR DS CHOKE, 12, MOD 55-65%
INVECTOR DS CHOKE, 12, LMOD 45-55%
INVECTOR DS CHOKE, 12, IC 40-45%
INVECTOR DS CHOKE, 12, SK 35-40%
   
INVECTOR DS CHOKE, 12, FULL, EXTENDED 75-80%
INVECTOR DS CHOKE, 12, LIGHT FULL, EXTENDED 70-75%
INVECTOR DS CHOKE, 12, IMOD, EXTENDED 65-75%
INVECTOR DS CHOKE, 12, MOD, EXTENDED 55-65%
INVECTOR DS CHOKE, 12, LMOD, EXTENDED 45-55%
INVECTOR DS CHOKE, 12, IC, EXTENDED 40-45%
INVECTOR DS CHOKE, 12, SK, EXTENDED 35-40%
   
INVECTOR, STD/PLUS CHOKE, 12, X-FULL 75-85% 
INVECTOR, STD/PLUS CHOKE, 12, FULL 55-85%
INVECTOR, STD/PLUS CHOKE, 12, LIGHT FULL 50-70%
INVECTOR, STD/PLUS CHOKE, 12, IMOD 45-75%
INVECTOR, STD/PLUS CHOKE, 12, MOD 35-65%
INVECTOR, STD/PLUS CHOKE, 12, LMOD 30-60%
INVECTOR, STD/PLUS CHOKE, 12, IC 25-55%
INVECTOR, STD/PLUS CHOKE, 12, SK 20-45%
INVECTOR, STD/PLUS CHOKE, 12, CYL 15-45%

Comparable percentages may be expected from the .410 bore at about 25 yards +10% above 5,000 foot elevation.
