Actually it's just 1/10th over a "max" load suggested by Sierra.

they guide you with <<23.5 - 24.9>> as the recomended load range.

23 grains is going 2700+ FPS
25 grains is going 2900+ FPS

This book reads very conservative in their data. Safe but conservative.

I trust Sierra's data more. as it includes a reference to FMJ bullets as well as SP's and HP's

With this powder the pressure signs started for me at max load of 25.3 Flat primers.
