The very first shot Harrison took, he actually hit the cup on top of the wall and knocked it off.
We proped a soad can up and when we hit it we could hear the BBs rattling around in it until they came to rest on the bottom of the can. We spent an hour shooting (it was the fastest hour in our lives).
On the way home from camp the boys were making arrangment with Grandpa to go up again next month for more shooting.
