Federal brass question

[Armored Metal]

Hey guys,

I picked-up a s### load of brass after last week-end's CQB. Quick question: Is the case on the left crimped 5.56 or plain old .223?

The case on the left has a crimped in primer (as is, I think, the one on the right, kinda hard to tell with that lighting).

There is no dimensional difference between 5.56x45 cases and .223 Remington cases. The differences are in the chamber and how the case is loaded.

Lots of people have bad things to say about Federal non-NATO spec brass. Mine has been fine so far. In fact, I just got my hands on 1000x IVI NATO spec brass, flash hold web thickness has been the same than the Federal brass I've measured so far.

Both cases have crimped primers, the recessed ring you see is the crimp that runs around the entire primer pocket.

Thanks for the link. Good info!

Thank you Biged, that's what I thought.

I know Federal brass has a bad reputation but I only load .223 loads that are not close to max. I've loaded Federal brass in the past up to 3 times with no issues whatsoever. I shoot them in my Ar for plinking and CQB matches.
