I stopped in the local shop today on my lunch hour and bought some Barnes Spit Fire TMZ. They are .451 and 250 grains. I went out and shot one at 50 yards to see how it was doing. It hit about 3 inches high dead center. So I moved back to 100 yards and shot again. This one was about an inch lower and still dead center. I left it there as I had it sighted in a couple inches high at 100 yards and it was dead on. I will report back once I shoot something with this round.
