Importance of ammunition inspection before use

So, how closely do you examine your factory ammo before use? A thorough visual check, a brief look, or maybe just a quick glance to get it oriented correctly before you slap it into the magazine/cylinder/chamber? Well, maybe the pictures and captions below will encourage you to look a little closer when you pop open that next box of ammo. Remember, your firearm is just a launcher; the bullet does all the real work (but only if it gets out of the casing and weapon, and manages to find its way to the target).



First, a couple of 9mms. The one on the right has a normal case/rim. The one on the left has an uncompleted or incorrectly formed case and rim. Not only is there no extractor groove at all, the case rim is thicker and larger in diameter than normal. This round was loaded into a Glock 19 magazine and the shooter attempted to fire it. It was jammed into the slide's breechface cutout so tightly that the slide had to be "persuaded" to open with light tapping:




Another case problem, but with a twist: the center .357SIG round has a casing that is longer than normal, and the bullet is seated deeper than normal. This combination could cause drastically elevated pressures (photo from an old "bad ammo" thread here on GT; photographer unknown):




Here are two rounds of military ammo that were discovered during range training. On the left, a .38 Special PGU ball round; on the right, a 5.56mm M193 ball round. Both had primers seated sideways during the manufacturing process, but the primers somehow survived being squashed into the primer pocket without detonating. When these rounds were loading into the weapons and struck by the firing pins, the primers went off, sending flame and smoke out of the SIDE of the weapons. No primer flame ever reached the powder, so the cartridges never launched their bullets:




And for the .22 rimfire fans, a lead round nose .22LR round that is so mangled, I can't believe it made it through the QC and packaging departments (once again, photo was found online, photographer unknown):




Got any similar photos of defective ammo? Post them, or a link to them, below. If you have a story or any info to go with them, make sure you post that, too!
