50cal vs Steel Beam
This video tests the penetration capabilities of various calibers against 3/16 inch steel I-beams. While handguns like the 9mm and .44 Magnum failed to even scratch the steel, rifle calibers showed increasing effectiveness. The .30-30 and 7.62x39mm penetrated the first beam, while the 7.62x51mm and .458 SOCOM also struggled. Ultimately, only the .50 BMG, specifically with its armor-piercing rounds, demonstrated the power to consistently penetrate multiple steel beams.
