Thank you gents for the information. I was able to put it to good use this week on a bunch of loads. I've got a ton of 223/556 brass and i've been able to better separate headstamps lately! Thanks to everyone for their contributions to this list! So far my experience is that the data shown is correct!

I've got a bunch of TAA brass that is too thick. What do you guys do with it? I can load it then run it through my sizing die but that seems like a lot of work. Did about 6 this way and I'd guess the chance of getting a stuck case is fairly high.

Suggestions?

According to cartridgecollectors.org, the 'T' stamp is most likely Tula of Russia. This stamp had 15 samples, while 2 others had 1 each.

TAA is Taiwan. I have also done thousands of TAA headstamps and they work perfectly to the point I can't tell the difference between TAA or LC. I can tell the difference if it has been fired out of a M249 or AR. The ones fired out of a 249 tend to be harder to resize but what I found to make it easier is a carbide die with plenty of lube.
