He had a primer blowout happen. After waiting a minute with the pistol still pointed down range waiting for a delayed shoot. After the minute we removed the cartridge.
At first glance everything looked okay, but taking a closer looks at the primer, and what had happened became all to clear.
You can see that one side looked like the bottom of a primer?
You can see once the primer is out of the casing that the factory had pressed this primer in sideways. The seating action bent the side of the primer and anval flush with the base of the cartridge making it very hard to tell (at a glance) that there would be any problem at all with the cartridge.
My question to you is- have you ever had this happen to you? Have you had a friend that this happened to? Have you even heard of this? Leave a post ether way.
I have shot alot of federal ammo with no problems but I will watch it closely from now on . I have had primers flip over on a Lee pro 1000 press they were fun to press back out .
Not sure I would call that a primer blowout. That’s a little different. A blowout is when you have too much pressure in the cartridge either cased by too much power, or a fast acting primer causing the powder to flash too fast creating up to 2000 additional pounds of pressure. Most of the time no big deal, unless you’re running at the limit loads. I tend to inspect my ammo because if issues like this.
It happens…anything man makes can and will blow up at some point…I had one of the 22 TCM rifles and had a factory Armscor round blow up when I fired it…blew the primer out and blew smoke and particles out of action…luckily it did not hurt the rifle, I hand loaded for it after that and eventually sold the rifle…
I have a good friend that is a firearms instructor for a local PD. He says it happens more often than you think. Tells all his officers to check their ammo every time they open a new box for defects like bad primers, bullet setback and plugged hollowpoints.
A good piece of advice for anyone carrying.
A lot of things go wrong in mass production. Not all of them get caught in quality control.
When I was in the service, my wife was in charge of the weapons for our district. She ran across that on occasion, and always told the guys to double check it when you draw arms and ammo.
Great photos! I’ve had a few boogered cases over the years, but none lately. Quality control is never 100% for any manufacturer, so it’s good practice to inspect the cartridges.
I have experienced a few flipped primers on my Dillon reloading press. It happens when the primer feed mechanism gets too dirty.
