I have a safe full of guns in various configurations and calibers, and ammo availability has always been a major consideration in purchasing something new. I am not a reloader, so my motto has always been that if WalMart doesn't carry the ammo then I don't need the caliber. To this day, the only caliber in my safe that WalMart doesn't have ammo for is my Blaser R93 in 375 H&H.
