5gr. Unique makes a pretty good load in a DEWC, but it will blow the skirt off a hollowbase. A solid wadcutter needs to upset just a little, so that's pretty close to 5gr Unique. Speer 14 is probably the manual that shows that as a .357 magnum load. If I go over those levels, I wouldn't flush seat the DEWC.
It's probably a compressed load at 5 gr.
