I have two kills I can recall one with a gun and one with a bow., and both were at under 6 ft from the end of the barrel /arrow when at full draw!
not very often I would even want to take shots like this, but was young and dumb yet!
I know over the yrs I have had countless animals, walk up and touch /smell me while hunting,. from bears to grouse and many others in between!
one moment I recall very clearly was a black bear climbing the tree I was up in and licking my boot, while staring at me, I think I was about 15 yrs old at the time bow hunting for deer!
bear was just super curious, NO ill intentions I felt, and made a lasting memory on me!
