Below you will find a pic of some WCC headstamped brass. The one on the right with the red die over the headstamp is with out a doubt WCC 5.56 brass with the NATO headstamp. The case on the left is WCC but this brass will fall out of my shell plate on a Dillon.
The specs.

Case on right .3725 at the rim , headstamp WCC 09 with the NATO Cross At the web .375. OD at the neck.253. ID at the neck .226
case on left .356 at the rim , headstamp WCC 06 with what looks like a very small 8. At the web .371. OD at the neck.248 ID at the neck.213. OAL1.756 Also note the longer taper coming up from the rim.

The pic.

Well I looked around some more and its not a 222 or a 204 Ruger. WCC made this brass like this for a reason. Maybe I'll try contacting them.

Not .222 that's for sure

.222 will fit in .223 dies just fine, only real difference between .222 and .223 is .222 has a longer neck

Any chance of talking to them and looking at the original packaging the ammo came in... do they have more?

This was i tip off, it sounds exactly like M862 SRTA training ammo. I have a few live rounds of it on my desk. The dimensions and headstamp are a match to what you posted.

A very hard plastic with a copper cap on the back of it. The cap seems to act like a gas block

Interesting. Why are the cases smaller than a normal .223/5.56? Seems like it would cause problems.

The boltface on the training bolt is slightly smaller to prevent a "normal" 5.56 round to be loaded into the chamber and fired. The bolt for these cases is lighter weight and doesn't lock into the lugs of the barrel extension like a normal bolt. If you managed to mix a live round in (possible if the bolt face WASN'T different) and it fired it would probably blow the upper apart as the bolt wouldn't be locked into battery. This brass is meant for use ONLY with the lightweight bolt so that it will still cycle correctly. Doesn't necessarily mean it couldn't be used as brass for a wildcat of some sort, but it shouldn't be used for 5.56 as the extractor probably won't grab it correctly.
