Raimey,
It's not so much that I doubt it's 9.3x75R Nimrod as I can't find authoritative info for such a cartridge in my admittedly poor references( I don't have Datig).Nonte shows making cases for what he refers to as 9.3x75 Nimrod. This case has a head size similar to 9.3x72R Norm.,but he showed using a .380 bullet.This bullet diameter would fit a "bore" dia.of 9.3.Municion shows a cartridge with a head size close to 9.3x74, but a bullet close to 9mm, as 9x74R Forester.This cartridge shows a case length of 74.6mm.In fact different names for these cartridges are listed at the heading and even they confuse the two.The markings on this T&S drilling would fit either 9x74R Forester or an old type 9.3(often had small groove dia.).We too often think the markings placed by the proof house is the nominal caliber,and they are not.I'm not convinced yet that there was even a cartridge called 9.3x75R Nimrod.There are Nimrod drillings marked by the proof house with bore and case length dimensions that could lead to a reasonable assumption that there was such a cartridge.I have asked for chamber dimensions, but haven't seen any. Maybe Axel can straighten us out on this.BTW,a bullet weight of 12grams is a little light even for 9.3x72R Norm.
Mike
