Yes i have used my Marlin for coyotes . To date i have taken 4 yotes , two heart shots and two through the neck and all dropped but one and it did a tail spin ran 20-30 yards and dropped . he was one of the two shot through the heart . All the shot where under 100 yards and i used the 20 grain XTP HP . Been trying for a fox but no luck so far !! Very fun and ACCURATE guns .
