#4 Buck Mod or IC choke copper or nickel plated are better ( don't tangle in hair as bad from being deformed) any will do. Dead Coyote Hevi-Shot also another good choice. All are death on Coyotes within 40 to 50 yards never saw much difference between 2 3/4 and 3 inch, didn't justify spendingmore for 3 inch.
