.270 Schuster and can cartridges be patented?

    The .270 Schuster, or .270 SCH, is a new wildcat European cartridge. It is basically a necked down .308 Winchester to 6.8mm (.270″).

    What is most interesting about the cartridge is that the inventor is trying to patent the cartridge case dimensions both in Europe and the United States (patent application #20110048269, published 3 March).

    I hope that this patent is rejected by the USPTO. Prior art must exist. I am sure wildcatters have necked the .308 Win. up and down to every conceivable caliber.
