The 7.62mm SLAP (Saboted Light Armor Penetrator) was developed by the USMC in the '80s.
Along with the 7.62mm version, a similar round for the M2 .50 caliber Machine Gun was also put in service. The 7.62mm round was given the designation M948, and the .50 cal. M903.
Both rounds used a Tungsten Penetrator encased in a discarding sabot. The 7.62mm SLAP is no longer in use, because of problems with the sabot breaking up while still in the bore, causing catastrophic failure as the penetrator pierced through the side of the barrel. The .50 caliber M903, was very successful, and will penetrate 3/4" High Hard Armor at 1500 meters.
A round similar to the SLAP round used to be sold by Remington, called the "Accelerator". It fired a 50-55 gr .22 cal softpoint bullet in a .30 caliber sabot. They loaded it in .308, .30-06, and .30-30. It had a muzzle velocity around 4100 feet per second.
