BARRIER SUBSTRATES Bullet Velocity All trajectories and associated velocities are from SAAMI minimum specification test barrels. An Oehler 83 model 35 P with model 55 skyscreens was used for velocity measurements. Bullet velocity was measured at a distance of 15 feet from the muzzle. Down range velocities shown in the ballistic tables are calculated with an exterior ballistics computer program. Trajectory Tables Trajectories are calculated using a computer program. A (-) sign indicates the trajectory of the bullet is below the line of sight. A (+) sign indicates the trajectory of the bullet is above the line of sight. All trajectories were calculated for standard atmosphere (Sea level, 59º Fahrenheit, 29.92" Hg, .07647 lb./cu ft. density). 1. Bare Gelatin Made in accordance with standard FBI protocol (10% ordnance gelatin). 2. Heavy Clothing The gelatin block is covered with four layers of clothing: one layer of cotton t-shirt material (approximately 5.25 ounces per yard, 48 threads per inch); one layer of cotton shirt material (approximately 3.5 ounces per yard, 80 threads per inch); one layer of Malden Mills Polartec 200 fleece and one layer of cotton denim (approximately 14.4 ounces per yard, 50 threads per inch). 3. Steel* Two pieces of 20 gauge, hot-rolled steel with a galvanized finish are set three inches apart. The clothing covered gelatin block is placed 18 inches behind the rear most piece of steel. This test event simulates the weakest part of a car door. All terminal testing is from actual firearms. The gelatin images represent one fired test shot. The data represents an average of five fired test shots. Individual results may vary.
