I concur completely that you shouldn't open these chokes. If you load these spreaders, you actually have a more versatile gun than if you had open chokes, as Don suggests--good for trap, skeet, or clays.
Incidently, the easiest way to load these is with a MEC 600 Jr. fitted with a 12 gauge STEEL drop tube. The tube fits right over the post in the wad, and you just load like you normally would with any other wad--using either a regular fold crimp or a roll crimp, depending on your hull or your preference. Very easy.
