Shoot the bow about 50 times before you install a new peep just to settle the string in, it will save you from having to repress the bow to put in or take out 1/2 a twist to get the peep to align
Yes I even shoot Bucknasty strings in before installing the peep not that there is anything wrong with the strings John makes, matter of fact I wont use any other string or cables.
