Why this rock is probably not a meteorite:

This is a sawn face of a rock that strongly resembles a brecciated lunar meteorite or brecciated eucrite. We suspect that it is not a meteorite because some of the clasts are too rounded (right of center) and others seem to have rims (upper right). Also, the specific gravity is only 2.4, below the range of any achondrite.
What is it?

Perhaps an ignimbrite?
