I don't remember writing the CROWN-crown/N proofmarks with the bore diameter given as mm to be pre-1910? Instead,I wrote above that the Mauser, Oberndorf commercial serial number dates the action to early 1912, so the barreled action must have been proofed after this date. It was not proofed by the Mehlis proofhouse, as this always added date of proof and ledger number since 1911. The 2.5 gramm charge was the standard sevice charge of the 8x57 with the 14.7 gramm bullet from 1910 on, neatly rounded up from 2.45g. The changes in 8x57 service powder charges, 2.75g from 1888 to 1901, 2.67g 1901-1910, 2.45g (=2.5g)from 1910 on, don't show altered ballistics or proof pressure, but rapid advances in smokeless powder technology. All 8x57 rifles showing the CROWN-crown/N proofmark were proofed by firing the prescribed "4000 atm Beschusspatrone". Thes proofmarks had the gauge number added up to 1911 (Z-M)- 1912 (Suhl), mm afterwards.
