50 bmg ammunition. Fits 12 guage.... just saying

I have about 70 rounds of 50 bmg rounds these are live you will need to show your pal to purchase. Would make a great gift or part of your collection gun room decoration office exc.. I can mail them aswell. You could also see if God will show favor on you and try putting one of these inside a 12 guage shotgun. If they weren't made for one another why does it fit then?.... just kidding dont do red neck experiments... or do I'm not your parent.
