weedwacker, the k98 is chambered for the 8x57JS Mauser, with a true .323 caliber bullet. Before the JS loading, there was the 8x57S with a .318 caliber bullet, used on some very old and very rare by now Gew98's as well as older service rifles. American loads are "anemic" for the safety reason that someone might put the JS loading in a 318 bore rifle. European's figure that their customers know what their rifle is supposed to shoot and accordingly load their ammo to full potential.
