What really happens when an M1 Garand fires the final round and the En-Bloc clip ejects with the distinctive “Ping”. Well thanks to the folks at ForgottenWeapons.com, you can see for yourself in super-slow-motion. The entire cycling process of a Garand has been captured using a high-speed camera running at 2000 frames per second (about sixty times normal rate). In this video, watch the clip eject at the 00:27 time-mark. It makes an acrobatic exit, spinning 90° counter-clockwise and then tumbling end over end. At the 1:20 time-mark you can actually see the two sides of the clip oscillating back and forth as the clip flies through the air.
