A crossbow is about the only way a 7 year old is going to get an archery deer. They just don't have enough strength to pull a heavy enough bow. In Tennessee I think a 40# pull is minimum to deer hunt. A friend of mine set his son up with a crossbow and put the kid in a stand by himself. The boy killed several deer with it before becoming strong enough to cock it himself. Dad was close by and they kept in radio contact. If the kid took a shot, dad came to get the deer or recock the crossbow.
