Been hand loading for 60 years and had my first squib yesterday. I had loaded up a test batch of ammo for my Mosin and, out on the range, I had fired maybe 25 rnds out of my bolt action, all of a sudden, pulled the trigger and click, nothing. First thought was a bad primer but then I pulled the bolt back out pops a spent case. Hummm! Further examination showed this dumb bunny has missed a powder charge in one cartridge. The primer fire had pushed a bullet 6" down the bore. Bullet was easily removed with a cleaning rod and went back to shooting. By the way I had a ball.
Giving this a bit more thought on how easy this would be for the loaders that move a loading tray around under a powder measure to charge their cases and miss one. Such a mistake with an auto loader could really create the problem that we read about every once in awhile. A person is using a semi auto , fires a fews rnds and click. First thought is a bad primer so pull the op rod back and chamber another round. OOPS, bad idea, if you have a squib load with a bullet in the barrel you have just created a bomb in front of your face. Think every time before pulling the trigger. Has everything, to this point, been normal? If not back up and check to see why.
