Excellent video! I've read 'Undaunted Courage' and always wondered what the 'air rifle' that was frequently referred to, really was. Ambrose presents the display of the rifle to the indians as though it was some form of entertainment, since it was unique to the black powder guns that most of the indians had already seen and were using. If it really could fire 40+ large caliber balls on one charge, that would have been quite intimidating.
Thanks for the continuing education.
