This cartridge has a bullet in it which is clearly not typical of the usual 7.62x39mm being 3mm longer than a normal ball bullet. The overall length of the round is therefore 58.4mm.
I have seen these cartridges before and initially dismissed them as being fakes however they seem to keep turning up so I’m now wondering whether these are legitimate dummy cartridges. Has anybody else seen them? Would they fit into an AK47 magazine?
