NW OK has the biggest yotes and cats in the state, never had any issues as of yet. I don't consider to have "killed it" unless I can walk up to it laying there lol.That would be my concern (using pheasant or turkey loads for a big dog). I wonder how many of the shooters (who say they've killed yotes with such) actually wounded some which ran off.
I've never used shotgun when hunting coyotes, but they (yotes) get really big in Seminole. As in, "..how'd that stray calf get in the pasture?" "That's no calf! That's a coyote!"
