Shotshell press hoppers

[baglock1]

This is probably a dumb question but are all shotshell press hoppers about the same? The reason I ask is because I just brought home my old Pacific press (still sitting in the corner of my dad's shop) and the hoppers are gone. If the inner diameters match up, I couldn't think of any reason why I couldn't use some other manufacturer's hoppers.

Anything I'm missing?

A year late with an answer, but...

Hornady bought Pacific and the Hornady is the same as far as hopper sizes. I have an old Pacific and two Hornadys. The base of one says Hornady and the top says Pacific!
