I have loaded several .357 Magnum cartridges with 9.2 grains of Unique behind a 125 gr SJHP This is right about middle of the road (maybe a little on the upper end) of the Speer reloading manuel.

I've checked it over and over again on the scale and checked the scale itself. The scale seems to be fine as is the load.

My question is....it seems to fill the cartridges up pretty well. I know it should be more than the .38 Special but this seems to be quite a bit. Almost comes up to the base of where the bullet ends up in it's seating position. (I need to snap some photos so y'all can see better)

Should it be this full? How full, on average, is the.357 Magnum cartridge when loaded with a decent charge of Unique?
