I'll bet the 9.5-grain load seems 'very stout'.

I tried loads at 9.0, 9.2, 9.4, and 9.6 grains; they developed 10' average velocities of 1454, 1469, 1497, and 1514FPS. These were small batches, so the velocities are approximate.

I'll find some Accurate#9 and develop a load of 1375 - 1400FPS. Then I want to do some muzzleflash testing.
