With how close to the lands you are loading, I treated it as if you are touching the lands (i.e. adding 7,200 PSI to the shot start initiation pressure). The recommended max load is 2.5g below Hodgdon's recommended max. However, the predicted velocity between the two corresponds closely. Don't take the charge weights or the predicted velocity / pressure from QuickLOAD as gospel. It's a calculated guess.

At Creedmoor equivalent pressure level it looks like you could gain about 160 FPS.
