beerbaron, you certainly can have a hollowpoint shotgun round, although like Billdog mentioned it would be a slug. In fact, most shotgun slugs these days ARE hollowpoints although the depth of the cavity and style of slug will vary from manufacturer to manufacturer.
This is the Barnes Expander slug, similar to handgun hollowpoint bullets:
Here is a typical example of a sabot slug and a rifled slug. Note that the loaded shotshell on the right contains a hollowpoint slug while the slug next to the shell is simply "ball":
Rifled slugs generally depend on mass rather than expansion to knock down game (humans included), while sabot slugs which tend to break apart in tissue:
Remington's Copper Solid slugs perform similarily to the Barnes Expanders:
One last example of a rifled slug without a hollowpoint, Remington Sluggers:
Don't ask me why the box says "Hollow Point Rifled Slug", that's the picture that went with the box. /infopop/emoticons\icon_wink.gif
Hope this helps.
