Hey guys, I live in northeastern NC and have shot a 49 lb coyote with a 300 ultramag, and the coyote still ran about 50 yards. The shot was a straight away shot, and I hit him solid in the right rear leg, with a 165gr barnes triple shock. The bullet entered his rear leg about 2 -2.5" off from his anus, and exited about middle way of his right side rib cage.
I also shot another coyote (41lbs) with a 25-06, 100gr triple shock. The first shot hit him in the guts, and had to shoot him again,in the chest.
Both of the yotes were shot while deer hunting. I have an FX5 on order and can't wait to try it out around here.
