Anybody know of a program that tells you roughly the trajectory of your arrow? What I want to do is roughly set my pins on an indoor twenty yard range and then fine tune at my outdoor range without missing my backstop. So if I know my arrow speed and weight have it tell me about how high it would be at 20 yards for each of my pins out to 60 yards. This is a new bow I got in August and have only set my 20 yard pin. I have tried the other pins just for left to right and left to right is good enough to not worry about missing left or right. Any help is greatly appreciated.
