Novice question - reloading steel wildfowling loads with mec sizemaster

[dextron 1]

Excuse my lack of knowledge but I'm considering getting started reloading my wildfowling shells. Can I use a mec sizemaster or do I need a steelmaster for loading steel cartridges?

I have a sizemaster in twenty eight  that is used for lead and I  don't know the true answer to this one but I would think that there will be a difference as there is a different model for steel.  mec might do some sort of conversion kit.  They do answer e-mail queries or contact an agent. Sorry that I can't  be of more help.

You can get a kit to make sizemaster to steelmaster. Is called steel shot kit.

I make and weigh, crimp on machine. Or i can run everything through the machine with my special pet loads.
