[Infobox - Cartridge goes here]

The 7.8x58mm Brandt or 7.8 Brandt is a rimless bottleneck rifle cartridge developed by Hower Elson Brandt in 478 and produced by the Brandt Arms Company from 483 onward. It was derived from the first generation Bressian smokeless cartridge, the 8mm Pattern 477 Royal, and was developed alongside Brandt's 482 prototype rifle. It would similarly enter service alongside the Model 483, the first Brandt rifle to see widespread production and distribution. The 7.8x58mm Brandt, in turn, would be widely recognized as the most successful of the early smokeless cartridges, featuring prominently in Bressian firearms, including most subsequent patterns of the Brandt rifle, as well as foreign designs,
