I would say a maximum of 3 full turns. Majority of bows 1 turn= 2.5-3 pounds. So if it were me I would not go more than 3 full turns, keep in mind however, that as you loosten your limb bolts your draw lenght may lengthen a bit. On my Bear Instinct, I backed my bow out 2 turns and I noticed my draw length was longer (more play in the string), not by much but it was a noticeable difference.
