0.315 SPORTING RIFLE
I think it is their own proprietary cartridge, not 8x50R Mannlicher.

The consensus, from what I've read, is that the .315 Indian round either is 8x50R Mannlicher or it's interchangeable with it.

While civilians (I suspect frequently interpreted to mean "non-Europeans") were prohibited from owning .303 rifles in Colonial days, I know 8x50R was a popular calibre because it was somewhat ballistically similar(ish) to .303 and would fit in an SMLE action; a lot of sporting rifles in India around that time were chambered in the rouund as a result, from what I understand - so it would make sense to resurrect the cartridge for the "modern" rifle, rather than going to all the trouble of developing a new one, at least in my view.

The specs given for the .315 Rifle cartridge on the OFB site seem to match the 8x50R Mannlicher; the cartridges certainly look the same and the (limited) ballistic data matches up with the info in my copy of Cartridges Of The World (12th Edition).

I know this thread is rather old, but I realised that we never really got around to actually answering the question I posed in it - and given things have been a bit quiet of late, I thought it might be worth revisiting?
