FBI Ballistic Test Protocol Test Event #1: Bare Gelatin

The gelatin block is bare, and shot at a range of ten feet measured from the muzzle to the front of the block. This test event correlates FBI results with those being obtained by other researchers, few of whom shoot into anything other than bare gelatin. It is common to obtain the greatest expansion in this test.  Rounds which do not meet the standards against bare gelatin tend to be unreliable in the more practical test events that follow. Gelatin blocks prepared according to FBI / FTU Specifications.
 

 

 

 

FBI Ballistic Test Protocol Test Event #2: Heavy Clothing.

The gelatin block is covered with four layers of clothing: one layer of cotton T-shirt material (48 threads per inch); one layer of cotton shirt material (80 threads per inch); a 10 ounce down comforter in a cambric shell cover (232 threads per inch); and one layer of 13 ounce cotton denim (50 threads per inch). This simulates typical cold weather wear. The block is shot at ten feet, measured from the muzzle to the front of the block. Gelatin blocks prepared according to FBI / FTU Specifications.
 

 

 

 

FBI Ballistic Test Protocol Test Event #3: Steel

Two pieces of 20 gauge, hot rolled steel with a galvanized finish are set three inches apart. The steel is in six inch squares. The gelatin block is covered with Light Clothing and placed 18 inches behind the rear most piece of steel. The shot is made at a distance of 10 feet measured from the muzzle to the front of the first piece of steel. Light Clothing is one layer of the above described T-shirt material and one layer of the above described cotton shirt material, and is used as indicated in all subsequent test events.

The steel used is the heaviest gauge steel commonly found in automobile doors. This test simulates the weakest part of a car door. In all car doors, there is an area, or areas, where the heaviest obstacle is nothing more that two pieces of 20 gauge steel.
Gelatin blocks prepared according to FBI / FTU Specifications.
