Ghostrider,
I suggest that when you fire the rifle the first time, see if a 323" bullet will easily enter the neck of the fired case. Mauser Oberndorf, made the neck area of 8x60 chambers large enough for .323" bullets and informed others of what they were doing. If the rechambering/rebarreling was done somewhere else(Suhl,etc), they may or may mot have followed Mauser's lead. The above test will show which bullet to use. With regard to the sights, only shooting it will show how it is sighted; whether it is for 8x57I or 8x60, and what distance.
Good shooting.
Mike
