Prime Ballistic shooting block ranges has high degree of ricochet & best for indoor or outdoor shooting ranges.
The test was done on single size block which is one of the basic block range from Prime Ballistic products.

This ballistic test was done to check & qualify the rubber block’s ballistic performance for both penetration resistance and it’s ricochet characteristics using a 9mm military handgun and ammunition. The main goal was to determine the number of rounds it would take to penetrate a single block shot in the 300mm direction and if any projectiles penetrated the block, how many round it would take until the first ricochet occured back through the impact surface of the block when the block was backed against a AR500 armored plate.
