Hi again all. Looking at a Mauser 98 rifle with the following marks and I can't seem to determine what exactly it may be chambered for. Marks are "8.9mm" over a 62. Proof is S.tM.G N18GR. Is this the 9 x 63 Mauser cartridge or perhaps the 9.3 x 62 Mauser cartridge? The 8.9 mm is throwing me a bit as that converts to .350 bore. Does anyone else have a rifle similarly marked? There are no chambering marks on side of receiver ring and these were found behind the frame lug. Any help on this would be very much appreciated. Danke, Jeff
