I went to the range yesterday morning to work up a 30-06 208gr A-max load and had 4 miss-fires, and a hang-fire (which happened after a 3 second delay) in 20 shots. I had just started a new lot of WLR primers the night before. I contacted Winchester today and they wanted the primers to investigate, but I wasn't going to ship them to them on my dime to them. Has anyone ever had this problem with WLR primers? I through out the primers and tossed the cases in which the problem occurred.
