Spent the entire PM at the range, testing out a few reload and stock ammo velocity at 100 yards, the results are following:
Norinco 5.56mm M193 Ball, the nork 223 is actually 5.56 NATO, they are pretty hot, even from a 14.5" M4 barrel I can get up to 3100 FPS, they are 3-5" MOA Ammo.
Here are my reload, close to MOA, I am amazed by the accuracy of the 14.5" norinco barrel, I used optimal barrel time method to find the right powder charge (QuickLoad Software), the result speaks itself.
