Not sure what the T223A is, but I'd get some of the 223LET1 or 223LET3 if you want a soft point bullet or the Speer Gold Dot .223. I tested some of the T1 and it works good. It's a bonded bullet and it yields a perfect little mushrum. The Gold Dot is awesome too.
I haven't blasted it through any auto glass yet... if I come across some, I'll give it a shot.
