I wouldn't want to test the penetration of #4 shot from a 3" .410 at 40 yards, would you? - Should be the same as say a 20ga, cause the MV's are roughly the same.

Like I said, the coyote will wish he were somewhere else if hit at 40 yards by 4 shot - and I doubt he'd come back, so it might be just as effective - but I doubt it would kill him outright.
