Use Of Choke Tubes

With the choke tubes you can control the openness or tightness of the pattern of your shotgun. The chart below lists the chokes (from open to tight), and the corresponding marks that indicate the choke of your shotgun.

A choke tube’s most effective pattern is determined by the number of pellets which stay inside a 30” circle at a specific target distance. This is a general rule, and actual distance results will vary based on ammunition, environmental conditions, and the bore diameter of the shotgun being used in the test.
