Shoot it a few more times and see if it will settle down. If it continues to turn the strings/cables are stertching due to poor quality (sad but true) and will continue requiring constant adjustments untill replaced with good ones. You need a press to change the peep rotation. By putting a twist or 2 in the string is the fix. If it can't get far enough or goes too far after twisting is when you swap strands from one side of the peep to the other (micro adjusting).

My 05 protec came with poor strings and contiued to strech until I replaced them with 452x strings made by Gibblet. Highly recommend the string and maker. After 200 shots the bow has stayed where it was set and the peep has changed only minutly and I atribute that to things just setting in. It has never sent shafts out so well although it killed deer last season inspite of the strings. Shot one deer dead even after the peep refused to turn even after bitting at it for a while.

Check your ata and I would guess it's off by a 1/4" already. The peep should not move if your string don't stretch.

Love my Protec! My brother pick one up this year and feels the same! We will be shooting side by side this season and I pitty the deer. The strings need replaced and it is worth it!
