I've been using Winchester Super-X 00 buckshot, from 2 3/4" up to 3 1/2", for over 20yrs. Absolute standby for me. Stuff hits the fan, that's the load I go to.

Other than that, I've been incredibly impressed by the Hevi-Shot Dead Coyote rounds, fantastic round, but they're pretty proud of them. I ran through a couple hundred rounds of them patterning and hunting before I found out how much my wife was paying for them when she was picking them up for me!! No longer goin to this round until the prices become reasonable. I wouldn't pay $4-5 a shot for premium rifle ammo, let alone a 50yrd coyote killer. It's good, but it ain't that good...

Stick with lead or heavier than lead loads between #4buck up to 00 Buckshot, copper plated shot is ok, but I'm not a huge fan. The Federal Flight Control #1 buckshot has done really well for me, but I've never been a huge fan of federal. That load ALMOST had me buying theirs exclusively. Just really hard to find.
