Ok so I understand the idea with the chokes on the shotgun are to control the spread of the shot (at least I think I understand that). But, I don't understand when you would use this and with what kind of ammo. An explanation or a link to a good explanation would be great. I don't really want to just google it because I would like to know which info you guys agree with (theory v practical knowledge).
Thanks for your help in getting me into shotgunning.
