The .70-150 Winchester is a hypothetical American centerfire rifle cartridge.
Appearing on cartridge boards of the Winchester Repeating Arms Company in 1888, it may have been nothing more than a display novelty based on a brass 12-gauge shotshell (rather than the paper cases common at the time, or plastic frequently seen today), shortened and necked-down slightly. Only one rifle was ever chambered for it, and it was never offered commercially.
