What's the likely range to be? Wax bullets with just the primer probably would work.
I use to love shooting my wax bullets around the house. I loaded everything from 22 RF to 30-06 with them. Powered by primers or maybe a grain or so of powder, even black powder. I used a block of modeling clay to mold my wax bullets in. Also used copper tubing that I chamfered to a sharp cutting edge to cut bullets out of a block of paraffin. Lots of ways to do it, so have fun.
