Made it out to the range yesterday for the first time in many weeks. I picked up all the brass I could find, and found something I've not seen before. I found a 223 that was missing the primer. I don't see someone knocking it out and then tossing it out on the range, so my guess is it was knocked out when fired. My first instinct was to toss it in the scrap bucket, as the pocket is probably loose. But then I got to thinking, for the price of one primer, I could see how the primer fits. Any ideas? Anyone else seen this?
