Remington

The 1,700-fps HyperSonic Steel from Remington is the world's fastest, hardest-hitting steel. The HyperSonic Steel shortens lead by up to 11% - an 8" lead difference at 40 yards that puts more pellets in the head and neck for quicker kills and fewer misses. The Xelerator Wad, the two stage system and hotter primer which ignites a small powder charge in the chamber, moves the entire payload forward slightly to control pressure.
