LOL!
This woman is an idiot!
The glass alone for a .50 is going to cost $1200, and I'd hate to fire a .50 I could buy off the Net for another $1200.
I belong to two .50 caliber associations.
In all their literature I've never seen a .50 advertised for $1200.
I buy ammo off the Web for about two dollars a round, but if I buy them off the shelf, it's $4.80 a round.
