Im shooting 31 inch Terminator 6075 with 100 grain muzzy broadheads. My bow is set at 65 pounds. My field tips were hitting the bulls eye everytime, but when i shot the broad heads they hit WAY low. I adjusted the sights and got the arrow hitting a few inches to the left of the bulls eye which is strange because when i miss with the field tips I always tend to hit slightly to the right. I again adjusted the sights and i can now get the broad heads to hit a grapfruit sized spot.
This bow is an old high country i bought at a pawn shop ten years ago. The string is about six years old, has a tube on the peep sight.
