Help Identifing a Cartridge

[bulletpusher]

Skeet and anyone else interested,

"More than likely, it's an M903 .50 Saboted Light Armor Penetrator (SLAP) round.

They also make an M962 Saboted Light Armor Penetrator Tracer (SLAPT).

.50 caliber SLAP ammunition was developed by the Marine Corps during the mid/late 1980s and was approved for service use in 1990 during Operation Desert Storm. It uses a reduced caliber, heavy metal (tungsten) .30 inch diameter penetrator wrapped in a "plastic" sabot or "shoe" of .50 inch diameter.
Since the mass of the saboted penetrator is much lighter in weight than normal ball .50 caliber ammunition, SLAP's velocity can be significantly and safely increased in an unmodified M2 Machine Gun. This produces a very fast round with a very flat trajectory which enhances hit probability. SLAP ammuntion is completely interoperable with M2 machine guns with stellite liner.

You're looking at a velocity of 3985 feet per second with a max effective range of 4921.5 feet (1500 meters) against 3/4" High Hard Armor (HHA).

The penetrator weighs 355 - 360grns. It's solid tungsten with no jacket."

The above information was furnished buy an individual on another sight that I frequent also. If the information is correct it more than answers my questions.

The person that I got the cartridge from had limited information about the cartridge and some very extreem speed quoted to him, I didn't think it would be a good ideal to quote something I couldn't verify.

Thanks for the help Skeet.
