Imagine, if you will, two miles of sandy beach. At one end is you, with a selection of rifles featuring prototype cartridges and heavyweight bullets. At the far end is your target, up to 3200 yards away. The target is made of wood, layered in one-inch thick sections. The goal is to test bullet penetration at great distance, which now means you have tohitthe darn thing. Repeatedly. Without a scope. This was the job for Mr. R. T. Hare of Springfield Armory.
