Anyone ever make one of these? I want to make a rimfire one and just wondering how thick the steel needs to be on the targets. I saw this kit on eBay and it got me thinking, http://www.ebay.com/itm/Do-It-Yours...649?pt=LH_DefaultDomain_0&hash=item460429df01 . I have plenty of steel, I own a large machine shop. Would be nice to through 1 or more of these things together.

All of my steel targets that are suitable for .22 are 1/4".
Don't know the type of steel, though.
That's as important as the thickness.
But they seem to be just plain old mild steel.
