I got it. blued Mark II target with a serial starting in 221, from beginning of the barrel to the back end of the bolt its 11" but it does not have a Ruger symbol on the back of the bolt
EDIT: It's a Heavy barrel too from what I've gathered, not a bull and bigger than tapered.
EDIT EDIT: I was trying to field strip it to make sure everything looked good, but I couldn't get that main spring housing I believe it's called, out!
It would pull down enough to not be flush with the barrel and didn't want to come out, but it would go back up into place with a bit of a "pop". The piece internally also moved so it wasn't able to open up the chamber, I wiggled that and now the bolt goes back and forth but I'm still puzzled a bit. The gun has extremely little wear. no scratches and looks pretty good so I don't think many shots at all were ever put through it.
