So it would appear, starting the same bullet 60 fps slower, it is only 1 fps slower at 300 yds. Using Hornady's calculator, at what point would the 2900 fps load pass the 2960.
When the same bullet is started 40 fps faster, by 300 yds it is 87 fps faster.
Arithmetic I could follow but algebra, geometry, and calculus must have required Hornady gurus and calculators.
