Dangerous brass that will hurt you

[Liberty]

Some of the more obvious defects to look out for. These dangerous flaws can be found in range brass as well as your own used brass. This is by no means a comprehensive list, and there are less obvious variations on these conditions that do not show up well in my amateur photographs.

Here is an example of case head seperation on both a 9 and 40 case

Split neck on .308/ 7.62x51


Here is the worst, full case failure on a .308, trying to fire this again likely will lead to damage, injury, or death.


Split case wall, don't load this either!



Hope this helps, be careful and have fun!

Macro setting will help your camera focus that close up.

Since I've been tumbling brass and priming it I've actually run across a few 9mm's with split necks

It is a cell phone camera.

Good info, as would be more detailed pictures as PewPewPewCo suggested , we could also add to these any other ones people come across

I should look into a digital camera, maybe on the next run to wally world.

What is the issue with the first two pistol cases and why is it an issue/does it cause issues?

The case wall has become too thin from multiple reloads and is separating from the case head. If this piece of brass was reloaded it would cause a kaboom. Once again, I will get a digital camera on my next store run. Sorry for the crappy pics.

I googled it, is this a better picture?

Not sure if it properly shows what you're trying to get at. Not a reloader.

Looks like someone didn't have the die setup correctly(had it too high). At least thats what it looks like to me?

I had some factory Federal .30-06 that split, just happens I guess.

I typically get 4-6 reloads out of straight wall cases and 2-3 out of necked cases. Any way you guys know to improve that?

For rifle brass annealing prevents split necks and not oversizing you brass prevents case head separation. Not loading it too hot keeps the primer pockets tight.

What do you need to do your own annealing?

A Torch, and a Very low speed drill

DD pretty much covered it. Some use tempilaq, quench in water, a socket to hold the brass but a torch is the main requirement.

That first brass .40 case looks like it was fired in a 3rd gen Glock. Pretty notorious for unsupported cases at the feed throat.

The first picture shows brass from a glock chamber. I was given some 10mm brass and when prepping it for reloading I found the flaw as shown in the picture. I sectioned one of the cases to see what the web looked like internally and found that the brass had flowed almost to the point of rupture in the unsupported part of the chamber. Those were much more damaged than most of the other glock calibers. If you look closely at brass from a glock factory chamber they will all have a bulge at the bottom of the chamber. As long as you are not loading high pressure loads and shooting the brass in a fully supported chamber you should be OK, as I have loaded and shot thousands of them without problems. The danger in shooting glock fired brass is the brass gets work hardened from stretching and as it becomes more brittle it has less ability to handle higher pressure loads without rupturing. This is from my experience.
