Backyard, underground shooting range

Dave 0

I’d like to have just enough property where I can dig a large hole, pour concrete walls and completely cover it over with a few feet of dirt, then re-plant grass in order to have a safe, sound-proof backyard, underground shooting range!

Of course it would have to be long enough to handle rifle targets as well; as well as a target carrier / target retrieval system, just like an indoor range.Backyard, underground shooting range -
