Bone head move on my part. I thought our lack of humidity was going to save me from trouble
I was trying to work up a load for the .264 win mag today, using 125 grain Nosler Partitions. I used some primers that I have had for likely a decade, but I keep my reloading stuff in my unheated garage (in NE Wyoming we have almost no humidity) and it appears to have done some damage. On over 50% of the rounds I had an empty click on the trigger pull. It would fire on the second try. The firing pin marks were strong and deep in the primer. They were CCI Large Rifle Magnum Primers. I assume they are damaged from being stored in an empty cooler in a garage? I thought the cooler would keep them relatively safe. For the last couple years I have reloaded ammo and bought clearance ammo and have kept it stored in the same garage. I am going to move it into the house now to avoid damage.
Any other reason or thoughts for the misfires?
