50 Caliber BMG Real Brass Bullet Shaped Bottle Opener

I've never had a real 50BMG in my hands but the casing appears to be real and previously fired judging by the slight flaring out at the neck. Plus some burned residue still inside it. The bullet is fake (light and you can hear it's hollow when you flick it), but why would it need a real one - this one seems to be nicely made with no machining marks left and the colour looks like fresh copper. It's held in the case solidly.As for its bottle opening abilities, it does a great job; I was worried the brass would be too thin/soft to be durable enough but it bit the top off my bottle tonight as if it was nothing, and I'd imagine will continue to do so for many years. And it just looks awesome on the shelf!

This is not a brass 50 cal spent bullet, there is no percussion cap
