Soak in diesel overnight to loosen dirt/debris, use choke key supplied with gun

A choke looks like a small tube that you screw in the mussel of some shotguns. It changes the pattern of BBS as they fly exc. a full choke will force the BBS into a smaller pattern than an improved cylinder. Hope this helps
Death and distruction. Not a good idea at all....
A barrel with a full choke.
System of changable shotgun choke tubes made by Mossberg. Accu Choke is their brand name. A shotgun choke is a means of reducing the bore size at the muzzle of a shotgun, to produce shot patterns that spread to a greater or lesser degree.
