The ADI World Class .223 Remington 55gr Sierra BlitzKing (brand part no. ADI9332153003166) pairs a proven Australian propellant maker with one of Sierra’s most respected varmint bullets. ADI World Class Ammunition loads the 55-grain Sierra BlitzKing boat tail behind more than 130 years of propellant experience, giving varmint and predator hunters a load built on match-grade consistency. The BlitzKing’s acetyl resin polymer tip sharpens the bullet’s profile for a higher ballistic coefficient than a comparable hollow point, then initiates rapid expansion on impact. As one of the rifle ammunition options here, this is a dedicated varmint and small-game round, not a hunting load for larger game.
