I doubt he would be 4.5 yrs old, maybe 3.5, but I would sway towards the 2.5 range. I would most deffinately draw back on that deer, can't say I would shoot him, but at least shoot at him. There are deer that big and bigger around here, but I have never had one in bow range yet, can't say I have had one in M/L range either, so I would try and take him, but thats just me, I don't have a deer that big yet!
