Company that would build underground Shooting lane on private property?

Another issue is Lead Mitigation.

This is the primary issue in my comment about affecting property value. It's not a matter of whether or not new owners want a range or not. If it's attached to the home, any future buyer will be concerned about lead making its way into the living spaces.

Did the dirt get there by itself?

Second the bad idea to bury Conex boxes. Plenty of info on the subject across the net.
Use curragated metal or plastic drain pipes, they are much cheaper and resistant to crushing forces.

Bury as many of these end to end as you need/can fit or afford, running from your basement connected to a "new septic tank" so that you can access the backstop easily to reclaim lead, and maintain the target backers. Use 4"x4" timbers to create a frame that has a repurposed materials conveyer belt section covering it, and shredded rubber pellets as a bullet catcher.

Lead mitigation isn't really a problem. The fella and I discussed that and had a few solutions. Neighbors would actually be the biggest issue, though they aren't extreme liberals as we have discussed guns and such before.

The idea is you don't say "hey I'm building a gun range". You have it designed but when building call it somrthing else, just as people with safe rooms and vaults often do. The issue is simply the legalities of shooting, even underground, as well as neighbors hearing it. Even with sound proofing it could be a problem. Get those two things figured out then it's simply money.

Curious who you're talking to to say it isn't a problem ? You want an underground range, go for it. IF you ever sell your home, or there's an issue with a neighbor. Better have a good lawyer and very deep pockets. Those EPA fuktards get wind of a range, especially underground and they didn't have input.................

Now if you do it, don't say anything to anyone. Rent a backhoe or find a forum member with one, pay them $$ do the install on a week day and call it good.

I don't disagree, I just bet I could do it successfully if I tried.

It can absolutely be done, it's just the additional cost of rebar, concrete, and
I- Beams would negate any real cost savings unless the materials are free, you own the necessary equipment, and you value your own time for labor at the same rate as a Mexican lettuce picker.

Nah, just clean sandy backfill, placed carefully. Maybe an underdrain and good drainage away. I bet most of these are installed by goofy bubba types.

Of course not, however, back filling doesn't require driving on it...

Conex shipping containers are designed to carry the weight in the corners. The only real structural metal is the very corners of them. The walls and ceiling are 14ga corrugated steel.

Without significant reinforcement, 8' spans of 14ga steel cannot support the weight of dirt, whether it's light sandy back fill or otherwise.
