This guide details an experimental technique for testing the durability of a 38g CO2 cartridge when struck by a 5.56x45mm NATO round from an AR-15 rifle. The experiment, conducted by Polenar Tactical, emphasizes safe range practices, including the use of PPE and proper backstops. High-speed footage captures the dramatic gas expansion upon impact, and the resulting damage to the cartridge is examined. This demonstrates an advanced application of firearms for material testing.
