Nope, they are good to go then

I pick up range brass when I am out in the middle of knowhere were we shoot at, and sometimes there is Berdan brass mixed in. Yours are ready to trim, if needed, and load away.

Back-up and take a look at the primer pockets. Are they crimped? See the ring?

If so you need to remove that before inserting a new primer.

Just to make it clear, 5.56 brass and 223 brass will have identical exterior dimensions once you run them both through your 223 FL sizing die. There is no such thing as 5.56 loading dies, it's all 223.

It was once thought that 5.56 brass was thicker and had less case capacity than 223 brass. This is not the case and in most instances the 5.56 brass has more case capacity then 223 brass.

The biggest consideration is case length. 5.56 brass tends to run long before firing. After resizing it will be WAY TOO long. You must trim to length. 1.76" is max. 1.75" is "trim length". If you trim to a uniform length, you will get more consistent crimps and better accuracy.

700? Pffft. I am working on processing 20,000 pieces of 5.56 at the moment.

That was what I was getting from most of the other forums that were saying it shouldn't be done.

I believe They are crimped but here's a pic to make sure:

It most certainly can be done and is done all the time.

If you are going to load 223/5.56 purchase a crimp removal tool. They can be had in many different styles.

Removing the crimp only need to be done once, so it's not that big of a deal. Simple, easy and quick.

Anyone who tells you that using 5.56 brass in a .223 is a bad idea is not a very informed loader. They probably have no clue that you can make 8mm Mauser brass from .30-06/.270/.280/.35 Whelen. Many things can be done if done right.

Remember, when you work up a load using the Lake City brass, it will be a load for THAT brass. Changing ANY component necessitates a new work up

For the OP and others on here: is a primer pocket swager really necessary? I have been using my RCBS deburring tool to remove the primer crimp without issues. I'm not saying that it isn't a better tool for the job, but would like to know if it's absolutely necessary. I chuck my deburring tool into a drill when I have a bunch of military brass to prep.

You can see the slight chamfer put on these three separate military crimped brass. The chamfer removes the crimp and makes priming the cases easier. The one on the right still has the red glue line.
