 For standard military Mauser 98 rifles besides common rechambering alterations, the internal magazine boxes have to be adapted by a competent gunsmith to function properly with 9.3×64mm Brenneke cartridges since the cases are longer and have a larger diameter than the 7.92×57mm Mauser military cartridges.The widespread availability of standard-size Mauser 98 rifles in central Europe and the fact that the .375 H&H Magnum cartridge and its necked-down version the .300 H&H Magnum with approximately 72.4 mm case length were too long to fit in standard-sized Mauser 98 bolt action rifles made the shorter 9.3×64mm Brenneke an interesting chambering option for European big-game hunters.Brenneke introduced the 9.3×64mm Brenneke with a 19.65-gram (303 gr) Torpedo Ideal Geschoss (TIG – Torpedo Ideal projectile) designed for big game and a 17-gram (262 gr) jacketed bullet with lead, bronze or a copper tip for smaller game.
