History

Released alongside the 7.21 Firebird in 1996 as the .30-caliber member of Lazzeroni's proprietary magnum family. The 7.82 Warbird uses the same massive case diameter as the Firebird, giving it powder capacity that dwarfs the .300 Winchester Magnum and approaches experimental territory. At 3,400 fps with a 180-grain bullet, it generates approximately 4,600 ft-lbs — rivaling dangerous-game calibers in energy while using a conventional rifle platform. Limited availability of rifles and ammunition kept it from wider adoption despite its impressive ballistics.
