Im shooting a Switchback XT with 28inch draw, 70lbs, and shooting maximum 350 with 100 grain heads. My arrow drops 15 inches from 20 to thirty.. Is this normal? I paper-tuned it and I'm almost shooting bullets. I'm using the zero effect rest and have a little fleaching clearance promblem, but can put 6 arrows in a 5inch group at 40 yrds. I thought I would be able to shoot with 1 pin for 20 and 30 yrds. One last thing my arrows are about an inch or two too long ( the guys at the shop messed up). Please let me know if I'm expecting to much or if I have a bigger problem.
