Thanks to all who shared their experiences with bullet deflection. Clearly it is a fairly common occurrence. Sure wish I could have a do-over on my shot at that bull. I found this picture on the SD card I took from a game camera I have on the same waterhole. Batteries had died in the camera, so I didn't have anything recent, but this one was taken on Aug 25th. I'm almost positive this is the bull I missed:
