Jani:

I've perused thru my info on target arms and sometime between 1921 & 1924, probably very near September, 1923 date for Suhl's beginning of date stamping, one starts to see a pre-rifling diameter like 7.6mm/46, 7.7mm/46 & 7.8mm/46 for the 8.15X46R. From 1912 on till the inclusion of the length, the diameter stamp only is usually seen. I assume most went thru the Zella-Mehlis facility but Suhl would have had just as high of a probablility. I do have a very tight chambered 8.15X46R target arm with the "181" bore stamp.

Kind Regards,

Raimey
