You can get lead shot at a reloading supply for reloading shotgun shells. But you must be careful with lead especially if you have kids or small critters because lead is toxic. I sealed up the burlap sacks that the lead shot comes in with wax, ZipLoc's and duct tape. After I had done all this I realized that I should have just bought steel shot. But it worked awesome. You do not need to drill for the Maple Shade spikes because the sub will sit on the three small spikes on top. Those are awesome improvements. You can go view them at their web site. These are massive HUMUNGOUS cones. Dale
