Home Forums Reloading Shotshells - TSS and Unleaded Load 20ga with old MEC?

I inherited an old 20ga MEC loader from my father. He used it quite a bit back in his dove hunting days. I would assume that this could be used to load shells with TSS? I have a shot gun for my boys that is limited to 2 3/4" shells and was thinking of loading my own once my current stash runs out.
