In layman's terms, it means that the G1 is based on a flat based spitzer and the comparison
between it and the new boat tail bullets will give you a much higher BC.
The G7 model is closer to the new bullet shape and this will give you a lower BC .
The G1 is preferred by some bullet makers because of the higher numbers . But for
the long range shooter the G7 will be closer in calculated trajectory to your actual
bullet drop so it is preferred for long rang shooting when calculating cold bore shots
at long distances.
