I recently bought a NEF H&R Pardner pump 12ga shotgun that come with a modified choke. The choke can be changed, and I'm thinking about getting a full choke to try to tighten the shot pattern up a bit. Problem is I don't know much about guns in that way so I'm asking how I can find a compatible choke of decent quality, and if changing the chokes will even be worth while.
