My pal and I were having this discussion on where to zero a rifle. He always does it at 200 and ended up shooting too high on a deer at 40 yardsin oklahoma last year. I sighted in at 100 knowing the longest shot taken will be 200 yards. Got mine through the lungs. It would seem to me that if your shots are gonna be less than 300, to sight at 100. What are some schools of thought here? EJ
