I realize Walmart isn't popular because of what happened to small downtowns after they moved in. Now Amazon is helping us with Walmart. Once on the wagon once under a wagon.....that is how life rolls. Anyhow, I only get Pomi tomato juice and few pieces of fresh farmed Salmon when I go there. I'm not suggesting one should buy ammo at Walmart on regular basis, but it being present in many small towns it can serve as emergency supplier. One must think of the future no matter how it looks. Buying guns able to digest what is at Walmart isn't a bad plan for the future. We can change name to "ChinaMart" if it makes you feel better.
Let me try to spell it out for you . . .
You have a reputation here as a poseur. My impression is that you are a person who likes to read about shotguns and offer your opinions but those opinions are not really grounded in actual experience. You come across as an internet expert and not an actual expert.
I happen to know the fella who started this thread. He's one of the best shotgun shooters I know. He owns dozens of shotguns and reloads for all gauges. He doesn't need to be told where to buy shells -- whether he's directed to Walmart or the factory itself.
Sometimes people would be better served by holding their peace and just learn by reading and listening. This seemed like one of those times.
