Say a berm 8' tall and 9' wide (better wider than tall) I calculate about 34 yards of dirt.
However, another suggestion. If only you and your wife are shooting there (very controlled shooting), how about 1 or 2 of those large round hay bales. Much cheaper than dirt and no EPA issues later on (haul the bales away and replace then). If you are worried about the possibility of a 30-06 going through a bale, place 2 bales back to back. I would think hay bales would last at least 2 years before time to replace. Round hay bales are big and should give plenty of target area.............
