underground range

2AZone has a really good point about the top collapsing. Conex boxes are designed to support a large vertical load, but only on their structural members. They're not designed to support a vertical load distributed on the roof.

True enough. but easily remedied by bolting regularly spaced "joists" supporting the roof load, and transferring it to the walls. Where the vertical load bearing strength lies. In construction we call this "Stacking the Load".

As to ventilation: As long as there is a positive air flow downrange exhausted to exterior. Shooter will be protected from accumulative effects.

Unless other structures or people are located in proximity to exhaust. No filtering would be required. Nobody has filters on their firearm muzzles when they "open air" shoot.

The other thing they do out here in the desert is either use one or two containers together and use them above ground as a pistol range. Sandbags and rail road ties at the target end with a powered roof vent to suck out the fumes.

These containers are not buried.

Quiet enough to not disturb the neighbors five acres away.

)Out of sight out of others control is a rule of thumb in LA county. What they cannot see or hear is none of their business. It will be a long bunker for ultra preppers.

Nice, sounds fun!

someday I would like to do this and while expensive Large concrete pipe (preferable square ) Would be the way I would do it. Line with walls with foam... Exhaust at the end intake at the front. Shredded rubber for the backstop.

[edgerly779]

Soft backstops muffle impact noise, shredded rubber, sand ,cat litter, etc. I used 3/4" armor from scrapping ww2 destroyer for backstops at target range in 1981. Got it for 10 cents a pound in 4'x11' sheets. They have since gone to a more modern system like Caswell.

I would also recommend some sort of noise abatement inside the feed and exiting air ducting.

This would be a lot more problematic than you think. Just the permitting itself would be a nightmare.

Connex-type shipping containers are NOT in any way suitable for burial, in any orientation, wherein any soil, rock, etc., loads the walls, or "roof". They are designed to be stack loaded, with the bearing load on the reinforced corners. You will most certainly have issues with rust, corrosion, and eventual seepage.
I use them as modified storage sheds, and have done a bunch of research on mods, loading, transport, etc. Find another way.

Getting a lifetime membership at A Place To Shoot in Saugus would be half the cost of this project which probably wouldn't pass permitting anyway.

As soon as you start digging for something this big, a neighbor will call the county and you'll have a permitting visitor.

Years ago I went to a persons house in the Eastvale area that had one it was a precast concretepipe I think it was about 50 feet long 4 feet diameter it was underground by about 10 feet down in his lower part of his house he had a bunch of foam in that room he shot from and he just had a light at the other end where he could hang at target but it worked just gonna have to spend some money

Just speculation at this time. Looking for options. Have a couple houses to sell in Valley and then looking out away from valley. Workplace is in Santa Clarita.

[Prepped and ready]

Burying a shipping container is not as simple as most think. Ive only done 1, but we engineered everything even the drainage and sump baisen.

Welcome to unincorporated Kern County!

Tax rate %7.25

CCW to all who are not excluded by criminal history or mental defect.

The kind of county you can sneak in an underground range and no one will care.

The dump is free to residents.

Get a house on Ave A. and be eight feet from L.A. County for a shorter commute. Most houses out there are on 2.5 acres. The Local hardware store sells guns. A lot of guns.

45 Minutes from Santa Clarita and a world away in freedom.
