Let me start by saying I know pretty much nothing about bows, how to set them up, and how to tune them. I shoot a Bear Attitude I picked up from Bass Pro a couple years ago and shoot 30-40 arrows about once a week into hay bale and foam targets. My problem is that it seems like almost every time I go to shoot, I have to mess with the sight (4 pin trophy Ridge that came with the bow) because the group has shifted from where I left it at the end of my last session. Usually it's shifted up about 4-5 inches and maybe an inch or two to the right at 30 yards. I'm to the point of not being able to adjust the sight any further up or almost any to the right. Does this sound like an issue with the sight, the string/cable, the limbs, or something else entirely? I've taken it back to the guys at the archery counter at Bass Pro and they moved the peep a little which helped for a bit, but I'm now back in the same position I came to them in, so I don't *think* it's the peep moving, but again - I know nothing. Any suggestions at all would be appreciated.
