Who on earth shoots a .50 BMG

[Dom]

Well, my largest is a .375H&H Mag, but I wouldn't call it insane

Now a 50 BMG, it'd be great to shoot, as long as you're buying me my ammo

Most use it for sport / range shooting. This is not a weapon you'd want to carry very far, unless of course, you are a big guy and enter Strong Man Contests, Waidmannsheil, Dom.
