Why the .303 Enfield? The Garand can easily get off twice the number of shots a Enfield can give off, and is just as reliable and accurate.

As for the "ping" noise...it's practically impossible to try and distinguish the "pinging" from the cacophony of warfare. If it came to that, GIs used to throw empty Garand strips to lure out foolish combatants. The Garand can be, contrary to what video games suggest, manually reloaded as well.

I can't think of anything the Enfield has that the M1 doesn't have that takes away the Garand's advantage of rapid fire.
