To all you guys who have a backyard range, How do you build your backstops. I currently am shooting at about a 3 inch thick hunk o tree about the size of a nightstand. Before we baught this house and cut down the big tree the back stop is made out of, The neighbors used to use said tree to sight in their rifles. Well This is fine and good for my .22 but I want to shoot handguns as well(not enough land for a rifle to be safe). I was thinking of some canvas bags filled with sand and stacked up and then covered in dirt. to my knowlage nobody lives behind where im shooting for at least a mile but still Ive been informed by the neighbors .22s shotguns and pistols. So how do you guys stop your bullets?
