Each wall assembly was built with 2x4 studs on 16" center and covered with 1/2" thick wood sheathing and exterior tar paper with fiberglass insulation placed between the studs. The interior walls were covered with drywall and then painted.
The exterior of the wood framed walls was then covered with three different veneer systems vinyl siding, stucco, and clay brick. The walls were located at a horizontal distance of 82ft. from the location of the shooting table. Each wall was then fired upon with each caliber of the rifle selected.
