Shooting a compound bow that isn't mine accurately?
Okay so I have a bow and im a really good shooter but I want to get a different bow with more fps and so on. I'm not willing to pay what a bow cost on the market right now (i have the money but car first). My dad has a nice bow and hes slowed down on bow hunting so I tryed shooting his bow (it fits me) but i constantly shoot low same spot every time and bow is sighted in FOR HIM. I will not mess with his bow because he still does hunt just not much. Why is it on for him but not me. I believe its how i look through the peep sight but i dont know. what do you think?
