Quick, but better alternatives - Do All Outdoors Double Blast Target

I bought two of these in 2012. The first outing, I shot through a back leg with 5.56. The legs I assume are made of a mild steel rod, and will not take direct impacts. The plate itself will hold up to automatic pistol fire, and light rifle. Can be flipped with a well placed magnum rimfire. Will not endure prolonged 30-06 fire. I’m a lover of 180 grain and the target will endure less than a box. The big circle will break off at the twist from the concussion of impacting the small circle fairly fast. The small circle will break off with a little more persistence. For $40+, I think that one is better off to buy a quality 3/8”+, AR500-550 plate and engineer a hanger based on your needs.
