Acknowledgements We'd like to personally and specifically thank Pat Childs at Fin & Feather in Iowa City, as he not only helped get most of our ammunition and other supplies, he was the brilliant gunsmith who worked with us to make this insane project much more practical. Without his help all of this would have been much more difficult and perhaps impossible. Anyone who uses our data owes him a debt of gratitude. And thanks to our spouses, who were not just tolerant but enthusiastically supportive of this rather nutty project.
