Home Forums Hunting & Shooting AR and Tactical Rifles 223 Ackley in AR?

I've got a several standard .223's and .223 AI's. I'll grab a .223AI nearly every time for its 100-150 + velocity difference. I frankly don't care where the extra velocity comes from; vudoo, physics, magic, pressure, whatever. Maybe its just that the 223 AI accuracy nodes always seem to be near or at max pressure, while my Standard .223's seem to shoot better a step down from max. As an example, I have a .223AI with 24" barrel that hammers 75g Amax's at 2950. Compare that to my Standard .223 McMillan Sporter with 24" barrel that won't shoot a 75g Amax or Berger accurately past 2750 and really tightens up at 2650 fps. Anecdotal for sure, but its my reality.

To each his own.
