See how easy it is to burn through ammo? And these guys weren’t even in combat. No wonder the U.S. Army needs lots and lots of .50 caliber SLAP ammo for its M2 Heavy Machine guns. Not SLAP in the Three Stooges sense of the word (nyuck nyuck nyuck). SLAP as in Saboted Light Armor Penetrator. Winchester: “It uses a reduced caliber, heavy metal (tungsten) .30 inch diameter penetrator wrapped in a ‘plastic’ sabot of .50 inch diameter, which is much lighter in weight than normal ball .50 caliber ammunition. The velocity of SLAP ammunition can also be increased in an original M2 Machine Gun to construct a very fast round with a flat trajectory to enhance impact on the target.” fas.org gives us the inside dope on the round’s genesis . . .
