Is there a big swing in ballistics between firing from rifle vertical (up), to firing position, and firing from horizontal, when powder has laid flat? That little amount of powder would lay flat, below the centerline, so the primer flash sets the whole charge off at once. Less forgiving powders would spike the pressures.
I loaded a 10.75x76 with 55gr.s of 3031, but was careful to fill the case with a non-migrating filler.
