I've discovered a few sites on the 'Net selling 25lb bags for $15, but
am hoping that the assembled brain-trust can suggest a less expensive
option.

Mike, try going to a trap range. If you explain what you want it for, they
may let you collect all you want for free. There is a local sportsman's
club that has a range and you can go out and scoop up handfuls (or shovel
fulls) of mostly #8 shot. You will get some dirt and debris mixed in, but
that can be sifted out fairly easily if it bothers you. Mixed with a little
epoxy, it makes a great slurry that will flow just about anywhere. Good
luck.
