Any luck finding Ammo?

Unless he has a huge family to help man all those guns, I wonder why he needs so many. He can only shoot one (maybe 2) at a time. I have 3, and only plan on getting 3, maybe 4 more. I also plan on 2 of those being the same caliber as what I already have so I don't need to stock up so many types of ammo.
Right now, I have an AR-15 (.223/5.56)
Ruger P94 (.40 S&W)
Winchester 1894 (.32 SPL)
Planning on a .223 Saiga, A shotgun, and another .40 pistol...and a 30-06, .308, or something along those lines for a high power rifle.
