The wall stopped every round. Including .375 H&H at 50 meters.

During our March 2024 GL renewal, an underwriter challenged public “bulletproof” claims. In August 2024 we live-fired a 7-inch single-wythe wall in Liberty Hill, Texas: 9mm, 5.56, .308, and .375 H&H Magnum at 50 meters. Zero penetrations.

Two hours inside the burn.

Ryan Runge, President of AECT, sat inside a CEB structure while pallets burned around it for nearly two hours. Thermal mass kept the interior livable. Not a lab test.

Tornado · 27 April 2014 · Vilonia, AR
Industry proof. Not a Parabellum job.

The first floor of a CEB home
remained standing.

On 27 April 2014 an EF-4 cut a 41-mile path through Vilonia, Arkansas at 170+ mph. Sixteen dead. About 200 injured. Bark was stripped off the trees. A 10,000-pound AECT 5000 press was thrown and wrecked. The first floor of a CEB home in that debris field was still standing.
