I have been a backyard shooter for awhile and we were blessed to move into a new house with a bigger back yard. Whereas I could only shoot 12 yards before, I can now shoot 25-30 yards and I've noticed an arrow flight problem. At 15 yards it's not noticible but at 25 yards my arrows are making a single counter clockwise loop. I'm shooting a Horne flintquest 50@28 60" TD with an AD trad lite, 4x4 RW slight helical arrow with a 250 head for a 635 total arrow. I'm actually shooting nice groups at that range and pretty much on target but I can see the rather large loop on the way down to target. Here is the strange thing, I have 2 strings made exactly the same (endless loop dynaflight 12 count) that I notice the arrow flight with but when I put the original flemish on it that came with the bow, no silencers but all else equal with the other strings (brace height and nock point), the arrows fly true. Is it possible for the string design to be causing this? Thanks in advance.
