Re: Crossbow bolt rising from 30-40yds?
The arrow is not rising from 30-40, it is just not dropping as much as you are holding over for. The hash marks in the scope are not calibrated correctly to the speed of your setup. Yours may end up 20,29,36,43 or something like that.
If you like your current bow and arrow package you have several options. See where it shoots with your current setup and tape a yardage chart to your stock for reference. Go to a slightly heavier or longer arrow and/or broadhead to see if this brings the trajectory closer to the 20,30,40,50 you desire. Upgrade to a new scope with a speed dial that allows you to tune the scope to the speed of your bow. Sight in at 15 yards or 25 yards and see where the others fall.
