WOW, that was something I was loading some primers in some cases today for my .223 and I had one primer that wasn't seated all the way in so I give it another slam and it fired, I'm betting I'm not the first guy that had this happen to him.
When seating primers I've never given one a first slam, let alone a second.
Just slam that sombeetch in there...
++ If that doesn't work the use a Hammer and beat it in
A Doe walks out of the woods today and says, that is the last time I'm going to do that for Two Bucks.
Just slam that sombeetch in there...
