RE: Dry Fire
I' ve actually dry fired a bow twice. Once when a release broke, the other when looking at a bow in a shop and someone had messed with the string. It broke under the serving. Both times caused minor injury, and soiled undies!
Want some real excitement? Take a 150 lb crossbow, put it in a bow press, crank that puppy down, and then let your rope break. Holy crap batman!!!!
