I ran into a problem with getting all of the rows of the loading tray to line up with the measure to drop the charge, so I just went to the stand... I think it's much faster to do the charging in a tray and eaiser to visually inspect for no or double changes in the cases.

I have both an RCBS single stage and a Hornady progressive press.

If you're talkng about mounting it on the press as a station, with the Lee turret, it would probably work out better for you, than the full progressive press that I have.

That flat piece attaches to the reloading bench/table and the measure hangs out over the edge of the bench/table top.
