A longer taper section to the constriction (parallel section of choke tube) insure tight patterns with less flyers. More pellets on target every shot!

Each choke tube constriction has been pattern tested and has thrown the best patterns with 4 through 10 shot. If you wish to use shot sizes larger than #4 shot use a more open choke tube for optimum patterning. Remember to pattern your shotgun choke tube with the specific shot shell load you are going to be using. Different types and manufacturers of ammunition will throw different patterns from the same choke tube. - Do not use any steel shot larger than #4 slugs sabots rifled slugs & 00/000 buckshot through a Carlsons Turk
