The 20 mm sheets were tested for use in shooting tunnels (enclosed ranges), whilst those of 30 mm were used for flooring in the shooting positions (butts).Both would be perforated by bullets fired during the tests but without any evidence of ricochet. Indeed, having been spent in the penetration of the rubber flooring and in impact with the floor structure beneath, the projectile did not retain sufficient kinetic energy, in any of the tested situations, to perforate the sheet again.
