HB, DE, Makes no difference. If the weight is the same and they are both made of the same material, they have the same total volume. The extra seating depth into the case of the HB is compensated for by the space in the hollow, leaving the net powder burning volume, which is what affects pressure in this instance, the same.
You should end up around 3.0 grains. I notice Hodgdon starts at 3.5, but the velocity they get is higher than most target shooting runs with, which is around 750-800 fps from a 6" barrel revolver.
