Hard to say without knowing the rifle's history with other loads. Velocity wise it looks like the new powder has about the same performance as 335 or 748.
Looks like the rifle's sweet spot for accuracy is that 26.6 grain load. Velocity wise, that might not be satisfactory for you so I guess I'd repeat the exercise to confirm it.
Perhaps the 27.5 grain load would be the best compromise between accuracy and velocity.
