10% Gelatin Blocks

All blocks in this category follow the FBI protocol for calibrating ordnance gelatin 240A so it can be used as ballistic gelatin. To pass the FBI protocol a standard steel BB .177 caliber (4.5 mm) is shot from an air gun over a chronograph at 590 feet per second (fps), plus or minus +/- 10 feet, 10 feet away into a block of gelatin, and the resting position of the BB is 2.95 inches to 3.74 inches (7.5 cm to 9.5 cm)
