Wasn't that long ago (20-25 years or so) that almost all hunting type tournaments used cardboard animal silhouettes placed in front of sand bunkers, and the targets were shot with broadheads. Of course, most clubs still have those sand bunkers, often in disrepair, but few shoot them anymore.
Excellent practice for hunting. Really enables one to test a lot of broad heads and figure out what flies best.
The advent of the expandable broadhead contributed to the demise of broadhead shoots as did the invention of the 3-dinmensional target. The wheelie guys don't want to damage their expandable heads shooting into foam or sand/dirt, and they're the majority of shooters in most areas.
Of course, the realistic 3-D targets are a lot of fun to shoot, regardless of equipment, but it's nice to have a sand bank, natural or man-made, to shoot broadheads into before season.
