Around 1960, Fred Barnes (of Barnes Bullet fame) built himself a 475 A&M-chambered rifle, based on a sporterized Enfield action. With its open sights that rifle weighed no more than 8 pounds. Being Fred Barnes, his initial handloading effort combined stiff charges of IMR 3031 behind his 600-grain bullets***. He, friends, and a small group of well-wishers went to an informal shooting range near Grand Junction, Colo. Fred sat down on the pea gravel of the parking area and crossed his legs to fire from the sitting position. He took dead aim at the base of a small juniper tree, which was tenuously hanging on at the top edge of a roadway cutbank.
When Fred pulled the trigger, everyone was watching for the impact. The shot went low. The tree was summarily uprooted! All watchers cheered as the tree fell, then, as a group, they looked around to find what Barnes' reaction might be. There he was, located several feet behind his original position, lying on his back, arms outstretched, holding the rifle above his head. Dust from the muzzle blast and his ignoble recoil-induced slide (he had absorbed well over 110 foot-pounds of energy) was still stirring when Fred asked, matter-of-factly, "Anybody want to buy a rifle?" He found no takers.
