Will the super-hardened steel hold up to one of the world's most infamous bullets? The short answer is not just no, but hell no. The .50 Caliber round is probably most notably associated with the sniper rifle and the Browning Machine Gun. The bullet cartridge itself has been made in many variants, regular ball, tracer rounds, armor-piercing, and even incendiary rounds that light shit on fire and / or explode when they hit. The massive semi-automatic sniper rifle can be shoulder-fired, and like its predecessors the rifle is said to have manageable recoil for a weapon of its size owing to the barrel assembly that itself absorbs force, moving inward toward the receiver against large springs with every shot.

In this video, a piece of railroad train track steel is put up against the test of withstanding a .50 cal round. The round has no problem piercing the 1 and 1/2 thick steel i-beam and penetrates with ease.
