I know exactly what your talking about. On Oct.30 I hit a 160 class 10 pt. dead in the shoulder. I got 4in. of penetration. I got all of my arrow back, he broke the head off at the threads. My arrow is mushroomed like I shot into a brick. I was hunting in SE Iowa. I couldn't get myself out of bed the following morning to go out hunting. I've been bowhunting for about 24yrs. and it still happens every once in awhile! Its part of it!
