A pile of dirt is more movable than 50 cinder blocks, some hollow and some solid?
Bales of hay for a .223? If you don't like my backstop, go spend $6 and shovel away. Please don't think i was making it law that you make one of these. This is the best solution for where i am and I am sure someone else will find the information useful. As for cosmetics, like i said, it can be painted..these were pictures of it within an hour of the initial construction...good grief.
There is actual science and research in this concept by Purdue university shooting range. You don't have to like it, but don't insult my intelligence. As i mentioned, the wood is free to me, dirt is not and would actually cost me much more, since cheap seems to bee what you prefer. I even mentioned that i may need to make a dirt pile now that i got a .308 for Christmas. For .22 and .223, this works fine and was a very quick effective solution.
As for shooting solid hard objects, you haven't researched the effects of a bullet on concrete at the angles I have chosen here. There is no ricochet...starting to feel like a broken record. A .22lr will actually create a molten concrete puddle that will embed itself in the lead at point blank range. At the yardages we shoot, the .22 just hits the concrete and falls behind the pink foam. The .223, if it gets through the foam only hits and falls with more lead splatter on the back of the foam...jacket lying in one piece on the ground in front of the concrete. Solid hard objects are not all the same when it comes to bullet behavior. On concrete, ricochet is only a player at VERY shallow bullet approach angles..there are no angles approaching that in my backstop. Find the Purdue PDF file and look into it for yourself.
Anybody else want to hop on the "gee what a stupid idea" bandwagon? For those that find this useful, you're welcome....that was my intent.
