I second that, all NS walmarts carry ammunition. Mostly just regular hunting calibers, lots of rimfire and a some shotgun. A few years back my local walmart had a great deal on 223 45gr (40 pack) but I don't see them anymore. When I started reloading 223 the price was so good that I bought a bunch of those bulk packs for the brass.
I remember those 223. When the Walmart 1st opened here the guy in charge of sporting was a handgun shooter.
We got talking one day and I told him about a Walmart I was in state side earlier in the week and all of the ammo they had. He came back with a book and it was unreal what he had access to. While he was there he would order us flats of AA and STS, 28ga shotshells you name it and excellent prices.When he moved on that was the end of it. I wonder do they still have access to a large selection of ammo just cannot be bothered to stock or order any.
