hey guys. i just took the plunge and bought my first shotgun. sporting 12. i have not had a chance to fire her yet, but did get a chance to clean her all up. i want to get into some form of clay shooting. either trap or sporting clay. also this will be used to fill any deer tags not filled during archery season. my question is can somebody tell me a little about the different chokes. the remington manual did not have any description of the chokes. also can i shoot slugs out of a choked smooth bore barrel without buying an extra rifled slug barrel? i cant wait to get home tonight to run some rounds through her. it is a beautiful shotgun. thanks in advance.
