Full choke

The choke controls the shot string, thus affecting pellet density at various distances. The tighter the constriction, the greater the distance that the cluster of pellets stays together. The looser the constriction, the faster the shot pattern spreads. The most common chokes ranging from tightest to most open are:

  • Full—might be used for turkey
  • Modified—might be used for pheasant and goose
  • Improved Cylinder—might be used for dove and ducks
  • Cylinder (little to no choke)—might be used for quail
Shot strings
The illustrations of shot strings represent the full load of pellets at a particular instant in time after a shotshell is fired.
