The 30 caliber 125 grain HP MatchKing® is uniquely designed flat based bullet was designed in conjunction with AAC (Advance Armament Corporation) and Remington Arms for the .300 AAC Blackout cartridge designed for the AR platform. This bullet has also proven to be exceptionally accurate in bolt action rifles and other .30 caliber AR chamberings. The jacket was specifically designed to handle velocities ranging up through common .30 caliber midlevel cartridges.

While they are recognized around the world for record-setting accuracy, MatchKing® and Tipped MatchKing® bullets are not recommended for most hunting applications. Although MatchKing® and Tipped MatchKing® bullets are commonly used for varmint hunting, their design will not provide the same reliable explosive expansion at equivalent velocities in varmints compared to their lightly jacketed Hornet, Blitz or Varminter counterparts.
