You know people say i shoot 30 yard max or what ever thats great for them but for me i will take longer shots if necessary. as long as you practice at long range its ok. for example i practice at over 100 yards regularly. now i know a 100 yard shot at a whitetail is not ethical but after practicing for a while at 100 yards the groups that you were shooting at 40 will soon be your groups at 60. just this last weekend i was in florida and hunted sika deer i shot one at 70 yards had a complete pass through and the deer made it 40 yards. as long as the animal is still and un aware of your presence and there is little or no wind a shot like that can be very ethical. however i am pulling 80 lbs so i have the neccesary KE at that range.
