No. For instance, the steaming converts rust. If the bore is rusty it could use it too then after everything is finished, clean the bore. In the case of the Savage 67 the bore is like a mirror even though the outside is covered with rust. If using a solution to create rust you don’t put it in the bore.Do you protect or seal off the bores when you steam the barrels?
Thanks for the in-depth explanation! I've got a few that need some attention and I thought about trying this before getting aggressive and sanding themNo. For instance, the steaming converts rust.

If the rust is thick then the outside may take some scraping with brass to get under the blackened rust to expose the red rust which will need another steaming to convert. A INGO member sent me some 50 bmg shells I will use to form one with a flat end and another with a curved end for scraping. Bluing is harder than brass.
After all the steaming is done the parts will be put into non-detergent oil, old motor oil is good since the detergents should be boiled out by then. Some use kerosene. It helps fix the bluing after which regular gun cleaning solutions and gun oil can be used.
A couple of points.Thanks for the in-depth explanation! I've got a few that need some attention and I thought about trying this before getting aggressive and sanding them
I will do some scraping but I may have to resort to sanding and polishing then rust bluing. For rusting I need better humidity setup.Barrel looks pretty good. Looks like you got some work to do on the receiver though.
