    Well, I'm not willing to buy one and bury it, but the dirt in the pics is saturated and I bet they compacted the shot out of it. I've seen a lot of blown out concrete walls from bad backfill and especially overly wet dirt.

    If you look at underground bunkers on line, you'll see they are all cylinder shaped. Same for any underground pipe. A square or rectangle shape cannot handle load like a cylinder can when put in the ground. Even a foundation (over time) starts showing cracks.

    I have a buried a conex. It's been fine for 5 years now. I did substantially reinforce it though and it's only 40' long.

    A company developing tracer technology hired a friends wife to engineer a multiple conex range, it can be done. According to her The cross section of 14 ga at a high incident angle is sufficient enough to withstand the needs. An internal backstop may be required to maintain integrity of the end.

    I know of at least one home in a very nice residential area that has a rather narrow 'bowling alley' in the basement. I've never seen a bowling ball in said home. Sadly, it isn't my home....but I don't bowl so it's a moot point.

    I've worked on 3 homes in the Denver area over the years that have indoor ranges.. They are large homes and the ranges are built just as a commercial range..

    It's not a permit issue or anything else other than a matter of cost.. How much money do you ave to spend?

    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 more just mean we talked about the lead issue way back when and there are some affordable solutions for a single lane private range that commercial ranges just don't have.

    I thought I remembered reading a thread a while back where Mark Larue built something like that:
    http://www.ar15.com/forums/t_2_219/1...nd_Range_.html

    There may be more info somewhere, I didn't search too deep.
