Just as steel plates are known for their vulnerability to M193, UHMWPE plates are known for their vulnerability to M855. I wanted to find out if that was true for shorter barrels or longer distances so I fired M855 at this surplus UHMWPE plate from a 14.5" carbine. The velocity was approximately 3,000 fps. So what do you predict? Please note this is regular M855, not the new magical unicorn EPR.
