If the deer can't wind you and have never seen a hunter before, then they probably won't run unless you make quick movements. I had 2 does come back and look at me 3 times (within 15-20 yards) because they probably had no idea what I was. On the third time, I shot one of them because I had one more tag and I new it was the last day I would get to hunt. As far as the rifleshots are concerned, they probably had no idea where it came from and didn't associate you with the sound. I doubt you would get similar chances on a 5 1/2 year old buck.....
