Walmart is selling what they have left of their ammo stock and then will not be restocking any ammo of any kind. They have been swayed to not stock ammo any longer until Obama makes a decision on gun control. There have been a few pages online (shadily) confirming this. It seems Walmart may know something we don’t in terms of law makers, etc.
