Five Felonies if you like the S&W 500 you'll love this revolver, a Austrian Pfeifer-Zeliska 600 Nitro Express. They might have a 700 Nitro Express too but i'm not sure. They say it's 3 times more powerful than the Smith and Wesson .500 Magnum.

Check out this article on it.
http://www.vincelewis.net/60magnum.htmlIs ammo over .50 cal even legal for revolvers here in the usa?
Get a load of the price for the ammo this beast uses.
5 rounds of .600 Nitro Express will cost you $180 and for the .700 Nitro Express five rounds will cost you $250. LOL! Thats $50 bucks every time you pull the trigger!
