How Bulletproof is a Monolithic Dome? A recent test put a Monolithic Dome up against assorted rifles and pistols ranging from a .22 long rifle at 15yards to a .3006 rifle at 15yards. After testing 6 different guns ranging in power, the Monolithic Dome and its curved structure, created by David South, Sr., and headquartered in Italy, Texas, proved to be bulletproof in that none of the bullets were able to penetrate thru the dome. In fact, damage to the exterior of the dome was minimal while the interior dome received zero damage. Domes are most known for being able to withstand lightning, fire, tornadoes, hurricanes, floods, earthquakes, and now, gun fire. — www.monolithic.com
