Gray metallic bubble rock

[firehorse12]

Looks like one of the iron ore bubble/bumpy type of rocks but it is metallic shiny gray. Cool lil' rock found two same place along with another dark gray very irony (red all around rocks found at after rain) rock that chips (will post that rock too). Has anyone ever seen this type?

This is the other rock that had a red residue all around it on the remote rock bed I found it on right by river.

Do a streak test using a unglazed piece of porcelain. I think it may be iron related. (also, magnetic?)
