I have developed my own steel targets. I would buy them but all my money goes for ammo and new guns. I live near a set of railroad tracks.If you walk along a set of tracks for a few hundred yards you will find the metal plates that the rails are spiked to laying on the side of the railbed. These make excellent targets and are very durable. The first time I used one I built a frame out of one inch black pipe and hung the target with the heaviest chain I could buy at lowes. It did alright but after about 700 rounds or so the chain was shot to pieces and the frame was falling apart as well. The steel was also so dented that some of the SKS rounds and 308's from my friends g-3 were going through. The next time I tried this I built a large wooden frame from 2x4's and suspended 2 of the plates from it. I also used white primer and then blaze orange paint on the metal. I used heavy nylon clothes line to hang them with. This worked great. The nylon got shot through a few times but for the most part would take several hits before it broke. The wood frames were also pretty damn durable and held up to a full days shooting.They are actually still sitting at my friends range.I've seen a few other posts about the railroad plates so I know it's not a new idea but thought it was worth mentioning. I put them out at about 80 yards and have never had a problem. I was very proud my last time out because I managed to hit 3 of 7 from my colt officers model at that range. The plates are about 6 inches by 15 inches(best guest) and about 3/4 to 1 inch thick.Hope this helps somebody
