I want to set up an outdoor range on our farm, for personal use. I have plenty of space and would think a 200 yard range sufficient for pistol and rifle target shooting. Can anyone offer a suggestion as to design and materials used for the target area-- how much dirt, height, etc? The area is low, alongside our creek and there are no houses in the sight line, nor are there any homes nearby-- the area is backed by woods. Noise is not a problem. I would be grateful for ideas, or sugggestions re: sources for range designs. Thought on target construction would also be appreciated. Thanks- Tom
