Hockey puck penetration - 9mm vs. 5.56mm
This video compares the penetration capabilities of 9mm and 5.56mm rounds using hockey pucks as a ballistic medium. The 9mm round, fired from a Ruger LC Carbine, was stopped by the first puck, while the 5.56mm round from an AR-15 easily penetrated multiple pucks. The test highlights the significant difference in velocity and sectional density between the two calibers.
