Hi every one, I have only been into archery about 8 months and I have a question, I have a Bowtech fuel compond bow and in the time I have had it the point of impact has shifted twice. The first time was dramatic, the point of impact shifted 6 inchs to the left overnite. recently happend again, it was perfect and then it started to shoot high and to the left. Same arrows, same shooter and the sights have not moved.I have not changed anything on the bow. The place I bought the bow can't explain it. Is this normal? If not can some one please give me some advice?
Thx in advance
