Rosewood mentioned above that his Walmart had a 2 box limit, I had never seen a limit on ammo from Walmart.
Apparently ours now has a limit as well.
I went in yesterday morning and there were around 40 boxes of CCI, 50 round packs of Maxi-Mag .22 magnum.
And a half dozen boxes of Federal 28 gauge.
I only have one .22 Mag firearm, a Ruger Single Six that has both cylinders, and I have a .30 cal ammo can full of .22 WMR.
So I called a friend that has 4 guns that fire .22 Mag, and told him that Walmart had ammo. He let me know later that when he asked for 10 boxes, they told him he could only buy 2.
