I don' t know about shooting coyotes with the gun because i have never shot one with mine. I have the new england arms single shot. I have shot crows and armadillo' s with mine alone with a couple of coons. The bullet is very fast and flat shooting. I wouldn' t go as far as saying that it isn' t very effictive over 150 yards. That may just depend on the shooter. I have shot armadillo' s out to 125 yards and it was a dead on hit. The armadillo was like jello on the inside after the shot. I will shoot a coyote with mine eventually, but will stick to head or neck shots. Behind the shoulder shot will be effective, but tracking will be almost certain.
