Just found several boxes of Winchester white box .380 ammo yesterday at Walmart $35.00 / 100. Happened to notice that the cases looked dirty/used and the primers were different colors. I took some pictures along side the same ammo that i purchased a few months ago. The box on the left is the stuff I bought this spring. The box on the right is the new stuff from Walmart. If you look close at the box on the left, the primers are the same brass color as the cases. The box on the right has two different color of primers...the darker primers are on the right side of the box. The lettering on the case heads also appears to be dirty, or dirt in the lettering. Not sure if anyone has noticed this before, or if it's even a big deal...Just happy to find them again.
