TEST PROTOCOL
BARRIER SUBSTRATES
BARE GELATIN
Made in accordance with 
standard FBI protocol 
(10% ordnance gelatin).
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).
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.
WALLBOARD*
Two pieces of ½ inch 
standard gypsum board 
are set 3.5 inches apart. 
The gelatin block is 
placed 18 inches behind 
the rear most piece of 
gypsum. This test event 
simulates a typical building 
interior wall.
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).
10% BALLISTIC 
GELATIN TESTS
The tissue simulant utilized in FBI 
ballistic tests is Kind & Knox or 
Vyse 250-A ordnance gelatin. The 
mixture is 10%, by weight. Properly 
calibrated 10% ordnance gelatin is 
a reliable tissue simulant. Validation 
of ballistic gelatin is conducted by 
firing a .177" steel BB at 590 feet 
per second (fps), plus or minus 15 
fps, into the gelatin, resulting in 8.5 
centimeters (cm), plus or minus 1 cm, 
penetration (2.95" - 3.74"). All gelatin 
was stored at 40°F until just prior 
to testing. The gelatin was placed 
10 feet from the muzzle of the test 
weapon (unless otherwise noted).
*Tests 3-6 utilize light clothing (e.g. the cotton t-shirt and dress shirt materials 
mentioned above), in addition to the mentioned intermediate barrier.
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.
