Check the sleeves inside and make sure that the contents inside are what's on the inside of the box! I purchased 1000 ct Winchester large rifle primers and when I got home i decided to open the box and inside of the box marked large rifle primers I found large PISTOL primers instead. Called the store and they agreed to change them out but gave me are fund instead since when I got there they were sold out. Just wanted to give a heads up in case some of you bought some but aren't going to use them soon. Store said I was the second box that was like this and that it happened at the manufacturer.
