The Clear Ballistics Long Range Block is perfect for testing terminal ballistics of handguns and rifles capable of penetration exceeding 16". This 10% gelatin block meets the requirements of the FBI’s testing protocol. It is larger than Clear Ballistics's standard FBI block because many ammunition companies and firearm manufacturers prefer a bigger block than normal for terminal ballistics testing. This block size offers the tester a larger surface area to aim at and hit, making it an excellent choice for semi-professional and professional shooters, as well as law enforcement agencies. 20" long x 10" wide x 10" high. Mold sold separately.
