Usualy what kind of 9 mm ammo been used on pre-1912 drillings?
Caliber marked as 118,35 (8,64mm), black powder proof.
Drilling liberated from Germany after ww-2.

It's usually some variant on the English 360 BPE case. 9.3X72R, 360 2 1/4"/9.3X57R/360 or 9.3X82R but it could be some odd case like 9.3X36R, 9.3X45R, 9.3X48.... and 9.3X70R, with the 118,35 being in the 0.341" to 0.350" range and being the pre-rifling diameter.
Kind Regards,

This is the pre-WWI method of German proofing. 118.35 is the bore gauge of the rifle barrel and corresponds to 9.3mm.
The other common gauge measurement for the 9.3mm bore was 108.49, the next size up.
Instead of the decimal point you often encounter a "slash" which would appear as 118/35.
You have a 9.3mm of some sort. You should do a Cerrosafe chamber cast to further explore what you have.

Yeap, Ramey, nothing new under the sun, before serrosafing simple measurements show probably it's 9,3x72R

Geno: Nothing new. With the 118/35, at least on the ones I have, the bullet diameter is around 0.355" instead of the normalized 0.366", or whatever 9.3mm would be. I'd slug the bore and use the 72mm cases. Here in the U.S.A. I think it was Buffalo Arms( http://www.buffaloarms.com) that had a quanity of RWS 9.3X72R cases recently and I purchased a couple hundred cases. I had purchased some converted 9.3X74R to 9.3x72R with the parent headstamp from BAC but the converted case and tight chamber usually don't make a nice pairing.\ Will you pleasure us with some pics?

Geno,
By all means do a chamber cast, but there is about 99% chance that it will turn out to be 9.3x72R.
As I do not have any Cerrosafe around, I just use the nearest old candle, with good results for this purpose.

It could be a 9.3x74R.
I have a double rifle in that chamber that is proofed 118.35.

I have a big piece of poor beewax for that, which is more harder than candle! (but softer than serrosafe)
This time I try to help my friend to find out caliber by phone, no photos yet.

Curl,
You are a very lucky man. I have seen hundreds of pre-WWI 9.3's, but none was in 9.3x74R; a couple in 9.3x57R and 9.3x82R; all the rest in the once highly popular 9.3x72R.
With kind regards,
Jani

I have heard the 9.3x74R called "the Goring caliber",not sure if it was a favorite in his hunting guns or,more then likely the choice for the Luftwaffe drilling rifle barrel.
