Hey guys,

I need help identifying a crimped primer in .223. I have attached a few photos of some brass if you guys could be so kind and let me know how to spot them. Other pictures noting the difference would be appreciated with a brief explanation.

Sorry for the picture resolution, they were the best ones that came out.

Thanks

I can't see enough detail in your photo's too tell.

Here are a couple of mine showing different types of crimp.
There will either be a depressed ring around the primer, or a few stab crimps.

Sig 88-- +1 on RC Model's comment; can't tell anything from your pix.

Now: From yr post, it is hard to tell what you want. Are you asking, "Do I have a crimped primer?" or "What do I do about a crimped primer?"

Gee, they're not at all hard to spot, either before or after the primer has been punched out in your reloading press. You can easily see the crimp on the primer, or its remains after removing the primer, on the edge of the primer pocket.

Military ammo is usually crimped--this keeps the primer from backing out which would jam a machine gun or possibly even a semi-auto firearm. Militarily, a jam can have very bad consequences. Commercial ammo is usually not crimped--it's one more step in the production process, and a jam on the range or in the game fields normally does not have dire consequences.

And what to do about them is you have to remove the remains of the crimp, so as to be able to insert a new primer into the primer pocket of the case, w/o crushing the primer. That can be done by cutting off the remains of the crimp, either by hand with any small knife, or with a powered tool, or by swaging the crimp back into the case, with a primer pocket swage.

If you have only a few such cases, the by-hand method is far cheaper than buying special equipment. If you have hundreds, or heaven help you, thousands, of cases to do, you need mechanical help.

Thanks for the info. Sounds like they are crimped and I'll be needing to remove them. I just wanted to make sure that I knew how to spot and what I needed to look out for.
