it been a while since I drilled a peep thank's for the update in drill bit size

Just remember that the bigger the hole the less accurate they are. You have to come to an equitable compromise between accuracy and vision (what you can see throught the peep) in a hunting peep. Something that will help you pick it up is aApperature Twilightpeep. Basically it has a brass insert which surrounds the peep and draws your eye in for fast target acquisition.
