Quick question for you BG users. I have been shooting the ascent for about a year now. Gone through multiple "sight ins" which required a new sight tape for dialing my yardage. Never had an issue. Always been spot on. Well I just got new strings and went through my 20-60 pins and I am getting great groups. I put my corresponding sight tape on, dial down to 70 and my group is 6" to 8" high. Is this tuning issue?
