Butterbolt, when you shot bolt rifles at Camp Perry did they say anything on the best way to grasp the bolt?  I note in the video cited above that the Krag shooter used a palm up grasp which is slower for a fast follow-up shot.  I learned that the bolt should be grasped with the thumb and fore finger which places the finger directly on the trigger as it pivots down around the grip of the stock.  Also there is no need to take time to place the thumb around the grip in fast shooting.  Any experience on this bolt use?  Anyone else?
