My dad this morning had three bucks at 20 yards the biggest being a high and wide 12 point. Needles to say when he shot he said the crossbow didn't sound right. The bolt went 4 feet over its back and the deer just trotted off. When he looked down the string and cables were destroyed. He has killed plenty of mature bucks over his years of hunting and 1 with this crossbow last year. He has never had a problem with it ever since he had the black limbs put on it. It has shot tight groups all the time. Just seeing if anybody else has had this happen. He never leaves it cocked after a hunt and it was shot lastnight when he was done with his afternoon sit.
