Mini 14's are dependable, and will deliver the goods on coyotes (assuming .223 caliber) and varmints. However they are not going to perform like a bolt gun at longer distances. My opinion would be 200 yards or less, ok for the critters mentioned. Over 200 yards a bolt gun would be more appropriate. Only my opinion, I sold my mini in the late 80's when I needed some cash and have not reacquired one. But it would shoot every time I pulled trigger.
