What choke do the police use in their riot shotguns?
That's why there is so much confusion around buckshot and chokes. The versatility of a shotgun and buckshot makes it the ideal tool for so many things. The home defender/cops would want a good, even man sized pattern at 15-20 yards. A cylinder/improved cylinder choke provides that. I want a basket ball sized pattern at 40-50 yards. If that's what anyone wants, a full choke is usually what they end up using. Don't take my word for it. Burn up $ and time figuring it out for your self. I already have.
