1. Specifications outlined above would also apply to 2 1/2" .410 ammunition in 3" chambers.
2. Where facilities do not exist for patterning 28 gauge open chokes at 40 yards, 25 yard patterning may be substituted with percentages     adjusted proportionately.
3. Double Barrel Guns -- Where one barrel has a different choke than the other, the more open choke should not shoot a tighter pattern than  the tighter choke.
4. Steel Shot -- normally steel shot shoots one choke size tighter than lead in the same choke tube. 

 To see what choke tubes are available for your shotgun, you can either look in our online catalog or refer to your owner's manual.
