Luv the SLAP, posted this pic before but still needs posting. This round is what got me started into cutting. M948 SLAP is said to have a non ferrous tungsten carbide penetrator in a plastic sabot with an aluminum pusher at the base. Althouth I've found it to be just slightly magnetic. They were made at the Furenede Fabriksverk (FFV), Karlsborg, Sweden for Winchester with a 62 gr projectile. It should measure .191" or 4.86mm. There is also a Slap T- tracer that has a M196 instead of the tunsten.
The tungsten core has a Vickers Hardness of Hv 1450, it will penetrate Type 5 Body Armor (classified), Mil -A - 12560 Ballistic + Armour steel (classified), and level 5 Ballistic Fiberglass at 1 7/16 thick. It was rumored that they where replaced with the M993 because the sabot was having seperation problems with muzzle breaks, except in was just reported another 5million(?) or something was just reorder in the .50cal, M903 SLAP.
The sabot seperates from 10 to 50 yards causing the projectile to travel over 4000 fps, giving better penetration at around 250 meters. Accuracy was not that great due to this seperation. They used the M13 metalic links, but pulled apart for indivdual use.
They are still floating around, but expect to pay about $20- each! wolf
