ever consider personal underground shooting range?

My home basement is about 3/4 finished. There is a crawl space under the family room with a 28" x 24" crawl-through door.
In my younger days I, and a neighbor, managed to get a 36" x 48" sheet of 1/2" steel plate, diagonally, through that door.
The top of the plate is loosely anchored to a joist with a couple 1/4" lag screws. The plate is at a 40 degree slope and deflecting everything down into the dirt. Also added a switchable light directed at the targets/plate.
Behind the plate is concrete foundation. That plate is 2 to 4 feet below grade on the other side of the foundation. I can shoot from 60' away, this is through an open door into the furnace room. Even rigged up a manual pulley target holder.
I've never hit the foundation but while playing 'quick-draw' one night I did manage to put a furrow into the crawl-through door frame. ;-\

I used to shoot IPSC, before the 'arms/optics race', and worked up many differing loads for .45 on my Dillon 550.
I've shot pistols up to .44 Mag and 22 rifles down there. I've never noticed the plate moving, even with the .44.
I close up the basement windows and you really can't hear much outside. I used to wait for momma to take the dogs shopping.
After awhile the smoke gets kind of heavy and I open the windows and turn on a couple window fans for an hour or two.

I din' do no steenking permits...
