RE: bow trajectory
Yesterday I decided to try the French tuning method. No paper tuning, new bow, rest and sitesremoved from last Allegiance. No adjusting rest I sited in a pin at 3 yds. Then went over to the 53 yd marker to tune my rest. Took 3 shots and that were right so I adjusted my rest accordingly. Next3 shots. X ring, right on X and third shot right outside of 10 ring.
If the arrow isn't set-up for center shot on the bow you can't just rely on the close-up shot. But I would think that if all you had was a short range and you paper tuned the bow you can site a pin in close and be effective at the long range equivalent.
However, I'd still recommend shooting at the longest ranges you can for practice.
