Unusual looking bullet in that cartridge, big blue nose suggests for low velocity.

I have a mystery 10.75 bullet I brought back from West Germany in the early 80's, was loaded in a Norma 10.75x68 case. Curiosity got the better of me one day and I pulled the bullet to discover no powder in the case and the case was Berdan primed. The bullet is an RWS steel jacketed hollow nose weighing exactly 280 grains. The deep hollow nose doesn't look to have been drilled, looks more like punched as it would be done in a factory and the 280gr 'rounded' weight seems to support that theory.

I have a little stash of the RWS 347gr steel jacketed flat point bullets and have seen these in pictures of earlier loaded cartridges for the 10.75x68 but despite some research online I haven't come across the 280gr hollow nose bullet listed anywhere. These lighter hollow nose bullets would have been the cats whiskers for the 10.75x61 and could have been loaded in that cartridge at some stage.
