What is fastest way to get the special stuff from Wild Wasteland in Fallout New Vegas

u should have been to the gun runners which has an awesome rifle and the way to get it is to got to a casino play roulett with lots of chips and if you win money save your game and if you lose money shoot a guy and wait till you die then you will go back to having some money and keep doing that until u get like 10,thousand cos the stuff at gun runners is really expensive. hope this helps!
