Bowdeerhunter..............Every bow and set-up is differant. There are way to many variables to guess............the answer is very simple...........practice! Practice from the elevations you plan to hunt at. Why take a chance? If you have a monster buck broadside at 10 ? 15? 20? 25? Do you really want to guess? No way! You want 100% confidence that you know where to aim, to PIPE that monster! Confidence is huge in bowhunting!

Best of Luck!
