I am going to try some coyote calling this winter. Since I live in a shotgun / rimfire only area thought I would try #4 buckshot. For my 12 ga. 2.75 in. ithaca 37 I have a 26 in. smoothbore slug barrel and a 28 in. full choke. I'll try both but which would you expect to pattern #4 buck best? In addition : can I expect a killing pattern at 40 yards? The cover for the most part is quite thick.
