I bought a brick of WLR primers a couple of months ago and had over a third of them ftf. I used them in my CZ527 762x39 with my worked up loads so I had primed 100 of them. The bullet was Serria 125gr sp's using cleaned range brass. Since I was working up three different powders, RE7, H322, and 1680 I knew the loads were right. All the primers were hand primed, just like I've been doing for thousands of other reloads, and I've use the WLR primers in the past with no problems. The cases were also clean inside and out and the pockets were also clean. On a few of the reloads I eventually got the primer to fire by throwing the bolt a few time. None of the pin strikes looked abnormally light because I checked them against the rounds that did fire.
Has anyone run into this problem with Winchester primers or did I just get a bad run of primers.
