I saw this on Guns & Ammo TV last night. New cartridge for the Desert Eagle. Said it was .50AE case necked down to hold .44 caliber bullet. Uh, correct me if I'm wrong but didn't Cor-Bon already do this and called it .440 Cor-Bon? I had a 10 inch .440 barrel for an earlier DE I used to own. Anyone heard about this, and what is supposed to be the difference?
