What is it that you think the match bullet will do better? Over normal ranges, lets say out to 300 yards there is no advantage as almost any bullet is accurate enough to kill a coyote. None of the bullets you mention will do him any good. If they expand, the pelt will be ruined as MKs can expand pretty explosively when they do, but if it pencils through, it might not anchor the dog. If match bullets were the only ones I had, I wouldn't pass up a shot at a coyote though.
I see you're in Little Africa, if you know Doc Kobus, say hi for me.
