I use N140 for 69gr 223's (which print ragged one hole groups) and N133 for 60gr V-max and 55gr SGK. Get much better velocities for a lower charge with the N133 and no compression of the load.
I hear what you're saying but a better case fill or even a compressed load from a higher charge can surely lead to more consistency as there's less space for the propellant to move around differently? Don't know.

I use it under 69 gr TMKs too, for 52/55 gr bullets I use TAC and for 40s I use exterminator. May have to change that soon though as no one knows when any is coming in!
