That makes sense, in essence, you are using your best judgement on most shots anyway. I realize its not a perfect world and deer will not come in and stand on your pre-arranged yardage. So a single pin is probably the way to go, eliminating the possibility of using the " wrong pin" . I just bought a new bow that is rated for over 300fps although I chrono' d it at around 280 with a 430 grain arrow. The trajectory of the arrow is very flat out to 25 or 30 yards. My previous bow was much slower so I always used a multi-pin sight on it. I do not have alot of experience hunting deer or knowledge of bow technology so your input is greatly appreciated. I currently have two pins set, one at 20 one at 30. If I range a deer at 30 yards with a single pin set at 20 yards how high should I aim? Would it be safe to aim at the top of the spine for a lung shot? I would practice this shot before I took it, I am just curious what you would do?
