I am just starting out in this sport and targets seem to be costly. I have purchased 5 targets that work well to 500 yards and have ordered a couple of more for further distances. I came accross a mature country black smith and he said try a plow disk. My first thoughts were colinder here we come. He had 2- 24 inch 3/16 one-way plow disks. I shot them at 7-8-9 hundred. not even a scratch, ding, dent ar any other sign off weakness. These new are under $50 and going by a large farm an asking if they have used ones you may find them really enexpensive.
