The 7.62mm type L cartridge pictured in the centre is 2.5mm shorter than the rounds to either side of it. It has the additional crimp of a Shkas loading and the bullet appears very securely seated. It’s still live and there’s no obvious damage to the point indicating that the bullet has been pushed back into the case although I suspect that this is what has happened, despite the deep crimp. Before I pull the bullet and reseat it to it’s correct depth I thought I would ask just in case the round is intended to be short for some obscure reason. Can anybody advise please?
