Has anyone heard of Amer-I-Can Enterprises? Somebody posted about them in a fb group. Here is there web site

I've bought from them before. Customer service is absolutely top notch. They were very accommodating to meet me on what would have been their days off when I was down in OKC a few months back. Took some of their 50 M33 to the range and it was about 3 inches up from the last batch of AE that I shot from that rifle, but my scope turrets had loosened and were free spinning so I don't know if that was the ammo or because the turrets shifted. Condition of the ammo was super clean and shiny and all rounds I spot checked were very consistent.
Would definitely recommend as a source of ammo.
