Shooting from a Norinco CQ with a 14.5" barrel here were the readings:
55gn 25.4 gn A2230 with 30 year old Winchester small rifle primers:

I have some chono readouts of Federal American Eagle (tactical, I think) shot from my SU16. I'll dig them up and post them later.
Here's a ballistic chart for 5.56 M-193 loads from a few different AR platforms.
