Information on 223/5.56 Headstamp

[doctorjohn]

While I was obeying my better half and doing some cleaning and discarding today, I found a container full of brass that I cleaned and deprimed at some point in the past. It is either 223 or 5.56. I suspect it is military 5.56. It is brass and boxer primed.

The headstamp is as follows:
In the 10 o'clock position is the letter "C".
In the 2 o'clock position is the letter "J".
In the 6 o'clock position are the figures "93". I assume this is the year of manufacture.

Does anyone have any information on this brass?

Thanks,

John

Norinco i think

That's exactly what that is... Norinco Chinese stuff. In fact, I think my case was CJ93, too. I wound up scrapping all of it... after the first (factory) firing, and loading the cases up, 1 out of 6 or 7 suffered neck cracks after firing.

It was a 'M193' clone, I got 3250fps out of my 20" Colt, which mirrors the other surplus I've fired through it... but it is, obviously, not true NATO M193.
