The Practical Guide to Man-Powered Bullets by Richard Middleton (2005, Hardcover)

This is one of the first really decent treatments of home cobbled projectile weapons that depend on a persons ingenuity rather than pocket book. There is nothing in this book that is beyond the average persons abillity except for the high powered air weapons. Among the covered subjects were stone bows, crossbows both with bolts and bullet shooting, slingshots, and low and high pressure airguns. Well worth the money I paid for it.
