The 555 round bulk pack is a new Winchester offering along with their new Hyper Speed HP load. It's a very hot load that matches the ballistic characteristics of the CCI Velocitor round. The Hyper Speed HP, like the Velocitor, features a copper plated 40 grain hollow point bullet. The bullet has a published velocity of 1435 fps at the muzzle, which works out to be 183 ft-lbs of muzzle energy.
