Does your sight have a level, and are you using it? If you are torquing the bow, that will do it.

If that's not it, start over. Take the rest and nocking point off the bow. Set it up from scratch. Make sure you are in centershot and the arrow is level. Shoot at paper. If you've still got that left tear, try a 75 grain point. If that doesn't do it, try a 150 grain point. The idea here is merely to get it to change.....If your bow isn't maxed out, do it. If that fixes it, change arrows. If your bow is already maxed, try a 250.
