The .50 Browning machine gun cartridge is an incredible, big bore, punch-through, knock-down caliber.
Slow motion footage of bullet impacts are just incredible.
How about one of a .50 BMG cartridge?
Jerry Miculek fires some armor piercing incendiary .50 BMG rounds through a steel plate. The slow motion footage does an excellent job showing the fireball upon impact. It also shows the bullet passing through that same steel plate!
After you see the action and destruction of these big bullets on a steel plate, you will never look at bullets quite the same way.
