Hi bernie,
Your range experiment make me thinking. I don't feel that BC may be enough to invert effect of speed and weight on trajectory.
Calculation give a "height drop" of 27.84" at 200m for the 350gr and 33.77" for the 512gr, with speed and BC indicated.
The heavier haven't the flatest trajectory.
with re-zeroized sights, your conclusion may be different.
If you have time to verify/reject theory, please post yours results.
