Still curious what velocity this load honestly develops. For example, Federal's LE223T3 loading is actually FASTER than Winchester's RA556B 5.56 loading (LE223T3 is typically 1-200fps hotter. Even though RA556B is 5.56 pressure, and LE223T3 is .223 pressure, and they are within 2gr prjectile weight of each other). .223 vs. 5.56 doesn't mean shit in the real world after the bullet leaves the barrel. What matters is velocity, not pressure (to external ballistics). I'm curious what this round ACTUALLY clocks.
