Re: Shotshell loading
The MEC Steelmater comes setup for loading steel shot. The comparable press to the Steelmaster is the Sizemaster, which is the lead version. Both of these presses are excellent choices and easy to use.
If you need higher volumes of ammo, you may want to look at the Hornady 366 or MEC 9000G progressive presses, these can turn out a lot of shells in a single evening.
(I currently have a Hornady 366, two Pacific 300's, and a MEC Sizemaster, all loading 12 GA.)
If you don't need to load steel shot, I would go with the Sizemaster, it easy to use and turns out excellent shells. If you don't need high volume, the MEC 600 Jr is also a nice press.
