so assuming your asking the question. is a .357mag good for deer hunting?my answer is yes. they make a 180gr. hunting bullet. that would do the trick nicley. as for if your asking what range its good for. take an 8 inch paper plate out to the range and find out how far away you can shoot at it from and hit every time. then cut that distance in 1/2. and that would be the max distance i would shoot at a deer with it.
