I have recently acquired a Winchester 1300 with a 22 inch barrel and 3 old model winchokes. I am going to take this gun turkey hunting. I know I need the full choke when turkey hunting but I don't know anything about the old winchokes. I haven't had a chance to pattern the gun yet and wondered if anyone had any experience/opinions about the old chokes. Will they do fine for the intended purpose or should I upgrade to newer aftermarket chokes. The chokes are the old winchokes that take the spanner wrench that you put in the hole in the knurled part that is extended about 1/4 inch.
