Brrrt wrong

The most modern 8x57 is the the 8x57 JS.

S= spitzer

J= infantry.


The original 8x57J did have a .318" bore, the modernized 8x58JS has the .323" bore.

A k.Kale model 38 turk is chambered for 8x57 JS. Its a large ring model 98 threaded for a small ring barrel.


Neweboarhunter- if this rifle wears its original barrel, 198 gr. bullets might not be the best choice anyway. These rifles had a twist rate for stabilizing 154gr. bullets. Usually later mauser Carbines such as Kar 98' s and G33/40' s are better suited for 198 gr bullets. The load that seems to work for me in just about every mauser I own is 50 gr 4064, 170 gr hornady RN bullets, and remington brass.
