Like you said, steel on steel isn't good generally. A good stiff brass or bronze brush will not hurt the rifling as it is softer than steel. Make sure it isn't just brass plated steel like some Chinese crap brushes are.
I put a large patch over them, wet patch with solvent and run it through my shotgun barrels. Works great as a tight fitting jag for the shotgun barrels, but wouldn't use them on rifling.
I pushed one down a bore one time on the recommendation of a gunsmith. He said one pass only after soaking a bore with solvent for 15 minutes. It sounded like a rake on a chalk board. Never Again.
They don't do much for a rifled barrel, the coils are not flexible enough to get down in the corners of the grooves.
They are fine for shotguns.
The best chamber brush I ever had was a .410 Tornado with an adapter to a pistol rod for quickly cleaning a .38 revolver cylinder between match stages.
I only ever use them to hold patches and used undersized at that; .30 brush in a .38... .40 brush in a .45 and such.
I hate to think of dragging highly stressed stainless steel over the edge of the lands in any of my guns. As note above, they leave a lot behind compared to a bristle brush as it is easy to describe an arc of untouched barrel from the edge of the lands to the next groove floor.
