You might want to shoot a few times at a target just to make sure your sights haven't moved somehow. That said I feel your pain....missed a big nine point (would score in the high 130's) after stalking him. I got to within 5 yards of where he had bedded down ( I didn't realize I was that close at the time as I couldn't see him in the tall grass) He shot out of there like a cannon and I got him to stop. I pulled back put the thirty yard pin on him and the arrow soared over his back. I paced it off later and should have used the 15 yard pin. In all the excitement I didn't judge my distance very well. Good luck on future bucks!!
