First off is your bow tuned correctly?

i have a bear charge with the trophy ridge 5 pin sight it came with. Didn't put on a peep cause they gave me trouble when i was about 11. I can hold baseball size groups out to 40 with no peep. my anchor is the nock of the arrow coming to the corner of my mouth and i have the string barely touch the tip of my nose. works very well for me. you have to make sure your doing the same exact thing every time and it took me awhile to decide this is the best anchor point for me. You might just need to mess around and try different things, or go put a peep on it.
