idk i have seen a k98, in experienced hands, hit the gong at a mile. I'm positive that a good 98 could reach out further in the right hands. I have also heard that with the right hand loads that you can reach out a lot further.Hi rommel......welcome to TFF.
Indeed the 8mm Mauser is a fine cartridge but "accurate @ apprx 2km depending on model"? I don't think so......2km is 2 kilometers (approx. a mile and a half).
If you're looking for the most accurate military rifle with a Mauser 98K action, take a look at the M38 Swedish Mauser in caliber 6.5x55mm.
