When I was hunting moose in Maine a few months ago I stopped in at the local Walmart to see what they had. I really needed some 209M primers for my MZL. Two guys were there that had just loaded an entire shopping cart with factory ammo. They took nearly every box of centerfire, plenty of shotgun and a load of 22 ammo. The cart was actually bending from the weight.
I wasn't sure if they were actually buying all that ammo so I asked. I got a less than polite response. The stores really should have put a stop to this. I'm guessing that it was all resold, probably on line.
As for my 209M primers; there were none to be had but I did find 4 bottles of Blackhorn209 on the shelf so I bought two. I was tempted to take all four but it just didn't seem right.
