Cheers guys dies are now on route so should be ordering powder and bullets soon.
I know this is an old post and I'm also only guessing here, but it almost looks like 7.85 was the original land/bore dia and 8.1 the groove dia. Not sure what the 240 is. But the dia markings would make it the .318 boreI've just got my grubby mitts on an 8x60 specially made for Clas A Heyer & Co Nairobi. It's a nice little rifle and looks to have some hunting left in her.
Now on checking the proof marks for the bore diameter it's stamped 7,85.8,1.240 then under neath 8x60 with an S right angles lower down. Now I was expecting either 7,9 or 8,2 to say the.318 or .323
So what size bullets does she need????
Well I've slugged the bore and as per the proof marks 8.16mm so is that a sloppy 7.9 or tight 8.2????
Your thought please on these interesting old rifle.

Aha. I thought so but forgot to do the math...some old Mausers only list the bore diameter some do not list anything other than caliber....etc., etc....240 probably refers to the standard 1-240mm twist rate, i.e. 1-9.45 inches.
Then get a reamer, an 8x57 barrel (or whole rifle) and off you go.Now how about an 8x64s!? I have ammo and dies but no rifle!

True but what a shame. While I love the 30-06, I think the 8x57 is just as good, especially with today's powders and bullets. Both are such cool cartridges but I never realized, till recently, how popular 30-06 has become in Europe. People either had 7x64 (some still 7x57) or 30-06 seems like. Many now probably have other calibers as well (300WM perhaps) but all the old dogs I meet have 06.Rifles in this caliber are rare , even in Europe where this cartridge has never really established itself. After the WWII the competition from the cartridge 30-06 Springfield was so big that there was hardly any chance for the cartridge 8x64S Brenneke. The cartridge 8x57IS was still in service and the cartridge 8x68S was also available , latter with significantly more power as the cartridge 8x64S.
By the way , If you own a rifle caliber 8x57I or 8x57IS , you don't need to change it to 8x60 or 8x60S. The difference in performance between the two cartridges is very small and not relevant for hunting.
You have to search for a ZG 47 in 8x64 ! I also do, since a decade …...Now how about an 8x64s!? I have ammo and dies but no rifle!
