I'd heard this before too... on INGO I think. It's a neat story and a neat rifle, that's for sure.From reading a few books on the subject, it seems like the air rifle L&C brought along was intended to keep the peace with the natives through a demonstration of superior fire power. They also never let the Indians know that this was their only one. Giving the Indians the impression that each member of the expedition had one of these 20 shot repeating air rifles, kept the Indians at bay. It was sheer genius.
