it has no measurable gravity, just an event horizon nothing can escape from

That is a black hole in a very simplistic sense. I'll try to bear with you here though.

I'm not sure there really is a way to catch something that small going mach 2 in atmosphere other there than pray it doesn't hit you. Also, if it were found upside down in a field, wouldn't it be carving a hole straight down?

There are a number of physics flaws with this SCP, and I'm unfortunately not the one to ask about them. I'd ask some of the physics questions in the research forum; I'm sure someone with a background in physics will be able to help you much better than I can.

Also, concept-wise, it's really just "a thing that does a thing," which won't hold up on the main site unless there's some kind of story behind it, which I'm not really seeing. Unless you can write about something other than relying on the reality-breaking nature of the box, it's not going to do very well.
