Thanks for all the helpful responses. I currently use a full-choked 30" barreled Remington 870 Wingmaster for turkeys. Has been very good for turkeys with magnum 5s, including one I killed out to about 40 yds. Last year a coyote responded to my turkey call, trotting about 50 yds out; a bit too far in my judgment. But still, I have no doubt I can kill a coyote with it and the right loads. I also have a Benelli semi-auto which would shoot 3" mags and might be the better choice for coyotes. At least until I get around to buying a dedicated coyote shotgun. ( My Benelli is a fancy shiny one that I don't want to damage in the field.) So you have given my some good ideas. Thanks again.
