There are a couple of steel targets I want to get. I think there like the tree with the paddles and tubing but no base or post. Also there are reactive ones that you can buy and modify to make what you want. I am gonna have to start a new link when I make something. The only one I made so far has 3 -3/8 mild steel plates. I made hangers and adapters to make like a saw horse out of 3/4 " conduit.
When I move to Winsconsin I will see if I can set up a steel range on my Uncle's farm. I know other people with land out that way too.
I would really love to have space to set up a range to my own specs.
