This test is meant to evaluate the performance of a small arm bullet in wounding a subject using the sheet metal door of a car as cover and wearing light clothing on their upper body. The test is not 'worst case' in that it simulates the portion of a car door without beams, motors or windows. As always, shoot well and shoot often. Firearm was 12 gauge pump with cylinder bore and 20" barrel length. Cartridge was Winchester Double X Magnum, 3.0" magnum copper plated 000 buckshot. Velocity at impact was not recorded due to chrono error ('350 ft/sec' was the reading on the screen). Let me assure you, going by the recoil of the gun, the velocity was right about where it should be. The block was placed 18" behind a 'car door', composed of two sheets of 12"x12" 20 gauge galvanized sheet steel, offset at a distance of 3.5" from each other. Two pieces of 12 ounce denim fabric was draped over the face of the block, simulating light clothing. Single shot fired at 10' distance from muzzle to the face of the first piece of sheet steel. Block calibrated at 583 ft/sec and 10.0cm penetration. Deepest penetrating pellet went 13.1", shallowest went 3.7". Average pellet penetration was 9.6".
