I have a question. Name brand ammo is name brand ammo right? I was at a local gun store, and I had said I could get tactical 223 ae ammo cheaper there. And the guy said walmart ammo was junk and told me about a glock they have that the frame is broke from using ammo from walmart. I just find it hard to believe a major brand ammo company would sell lesser ammo walmart and hurt there rep. Is there any feed back on this?
