I have a mec steelmaster. I hand weigh my powder and my goose loads I use a empty primer tray just tape over half the amount of the holes for the right amount of shot. On my duck loads I use the shot bar. If you load any hevishot you HAVE to weigh each shot charge. Ballistic Products has good reloading manuals and components. Bit of advise<do not use any information unless you see it directly out of a reloading manual and do not try to tweak any loads as it could cost you or your buddys life>steel shot and hevishot are very sensitive to small changes in the load and you could send the pressures through the roof.
