I had a new string put on my Browning Ambush earlier this summer and it shot great but I have shot probably 400 arrows since and now my peep and string loop are off the the left about 45degrees or so and my groups went from 2" @20 yards to 8" @ 20 yards so my question is .. can a string twist affect grouping like this? If I have the shop put a twist back in to realign the peep will the groups come back? Or is there more to it?
