Is the gelatin transparent ? Yes, clarity is less than 25ntu

Can the ordnance gelatin be re-used ? NO! Used blocks should be discarded

How may test shots per block ? 5 test shots

What are the dimensions of the test block ? Blocks used in testing of conventional pistol ammunition are approximately 6.25" x 6.25" x 16"

Where do you shoot into the block ? The initial block of gelatin used in a test is referred to as “The Primary Block”. Each Primary Block is utilized for a maximum of five shots, one in each corner, approximately 1.75" from the nearest edge, and one in the center. Placement of shots results in substantially the same penetration as single shots into virgin blocks of gelatin. Any shots, which cross the wound path of previous shots, are re-fired. Primary blocks are not utilized for more than five shots, to include any shots, which are re-fired.

What is a Stopper Block ? Because some shots may penetrate more than one block of gelatin, one or more “stopper” blocks are placed behind the primary block. The stopper blocks may be utilized for more than one test, if the wound channels are not crossed. At the end of each test, the stopper block is placed back into the refrigerator while another stopper is utilized with an unused Primary block. Stopper blocks may receive more than five penetrations; if no wound channels are crossed, (e.g. a stopper, which has five penetrations of 3” into one end, can be flipped over and used as a subsequent “stopper.”)
