I have a Copper John and it's a great site. The level and circular housing has helped me improve my grouping at longer distances. Like MO said it sounds like your peep is not lining up correstly or you need a larger dia. hole. I shoot a peep with the largest dia opening I can get. This will also help in low light conditions. It's called a "NoLose" peep with four slots instead of three. With this peep it opens up the distance between strings. It's just large enough to out line the orange housing which helps me with constant head and anchor position. The level will also help your gpouping. It will stop you from canting the bow. You can also shoot without a peep but with a good working peep it's like having a rear site. I think they made this site with a peep in mind. If not they still work well together. JERRY
