Hello stevieboy, my experience with the NATO ball is consistent with yours, I have used literally thousands of rounds of Wnchester NATO/Q4318 124 ball and a lesser amount of the tan box/Ranger NATO. Quality and consistency of both have been excellent. Both tend to run about 50-100fps faster than regular US commercial ball of the same weight in my guns, depending on the particular gun/barrel length,etc. It is more energetic and works especially well in guns with heavier slides and/or stronger recoil springs. I did chronograph some M882 Federal NATO ball. It displayed velocities consistent with American commercial ball of the same bullet weight. I have guns that function a bit lazily with regular Wally World Winchester 115 ball or the Federal red box/American Eagle 124 ball, for instance. I have had no problem with it, but the Federal red box 124 is about the lightest factory 124 ball load that I can recall chronographing in over 35 years. If someone wants a very light, reasonably priced factory plinking load, this might be it. I much prefer the Winchester NATO ball, either tan or white box, over any other types of ball ammo commonly available to me though. ymmv
