History

Wilhelm Brenneke was a prolific German cartridge and bullet designer responsible for the Brenneke slug and several sporting cartridges. The 7x65R was developed to provide a powerful, versatile 7mm hunting round for the German market where combination rifles (drilling — typically two shotgun barrels plus one rifle barrel) were the dominant hunting arm. The cartridge remains in production by RWS and other German manufacturers and is widely used in Central Europe and by hunters pursuing red stag and wild boar.
