Stan, since you already have the Supersizer you could buy a MEC 600JR setup for 3" or spend some more and get a Sizemaster.

My .410 Sizemaster was set up for 2.5" but came with all the parts to convert it to 3" in the box and I'm almost certain that the 600JR also has the parts.

The MEC single stage presses aren't fast but they load good cartridges. I roll crimp 24 gauge but that's only because there is no fold crimp reloader made for the 24 gauge.
