Seen that in NW Tucson area.
Assume it is reloads and that slows me down.
Factory ammo would be of interest, but I have never stopped to see what is is.
What do you have against reloading, I've done it since I was about 12. I was hunting with the men at that age and very good at hunting quail and dove.
I buy very little factory ammo now. But never sell any, that is probably illegal and also risky because of liability.
But, I won't run out of ammo.
