  • Hornady Primer Pockets

    OK, another Primer Pocket question. I recently bought several boxes of Hornady 73 gn ELD Match rounds (.223 Rem), fired same, and set up to reload the brass. My 1st indication of trouble was that it took more force to unseat the primers and they pressed out kinda "cone" shaped, like they had been stretched before popping loose. I put it down to soft primer cups and carried on but then I couldn't get a primer to seat. Wound up having to run the brass through my Primer Pocket Swagging tool (I normally only use it for military brass) before I could get a primer to seat. I tried Winchester, CCI, and Tulammo primers, none would fit in the pocket before swagging. Has anyone ever run in to that particular problem before? Oh, by the way, there were two different lot numbers for the ammo.

    What powder/charge are you loading them with? There's the possibility that brass expansion is happening at the case head from a pressure issue. . Try running a few cases through the die with the deprimer removed. If it requires a lot of effort, that's likely what's happening.

      Papajoe, this is the brass from several boxes of new Hornady factory ammo, not reloaded. Two different ammo lot numbers and both have the same issue. Interestingly enough, I also have some unfired Hornady Match brass that works fine, it is only the factory loaded brass that has the issue.

        I would bet money the primers are crimped in from the factory. It seems like I read something about this , maybe some Hornady Match ammo having crimped in primers. but I don't know exactly why, heard match ammo for military and also pressure was backing uncrimped primers out....don't really know why .
        If there is a circle around the primer ....it's crimped.

          Those are crimped. I have used them in the past

            papajoe222, when brass expands from an overcharge the primer pocket expands also and gets loose, not tighter.
