I have used #2 on coyotes and had superb results. Recently I hit a coyote with 1-3/8 oz of #4 copper plated lead at about 40 yards and I have never seen a dog drop so fast and not even quiver. I have recently been re-thinking my old love of 12 pellets of 00 buck buffered in a 3-inch shell. Coyotes have really thin skin and not a very tough body/bone structure and #2 lead or even BB would be great, I think. I might just get a jar of nickel BB for my next load of coyote rounds. In response to the above question about cushions and buffers, I think buffer is extra important in big shot sizes, but I have not seen much advantage in felt cushions except in tuning shot column height. FWIW, I have what has to be one of the cheapest Remington factory extended turkey chokes available for my 870, and it really performs well even with 00 buck loads.
