[QUOTE="CAR-AR-M16, post: 1650568, member: 204"] I do not know what is being said in the other thread that you mentioned, but here is a nice explaination from Briley Mfg. (a leading manufacturer of shotgun chokes). [I]Ok, so how does a shotgun choke actually work? Let us begin first with an easy metaphor, a child in out in the back yard playing with a garden hose. He discovers that if he puts his thumb on the end of the hose it goes further. That, kind of, is similar to what happens with a shotgun.
