I have a ’92 SRC with a very pitted bore. The rifling is easily visible.
There must have been a lot of black powder loads through it. Many cleanings with Hoppe’s with long soaking periods still results in very dark patches. Is that the best that I can get or should I use a different bore cleaning solution or method?

About all you can do is make the bore shine more by removing the rust. I would get the bore brush and go at it.

To add to what Bob stated, use Kroil with the bore brush. I would soak the bore overnight with Kroil, then scrub the bore until the rust is gone.

Plugged chamber with rubber stopper and filled bore with fresh Hoppe’s, left over night (3 nights) with draining and new bore brush through the bore.
As indicated it took three night to get clean patches coming out.

Finally getting back on project cleaning my ’92 pitted bore.

Done a lot with Hopes 9 & cotton brushes.

What other kind of brush should I use?  Phosphor Bronze?

What brush not to use?

With a bad bore you can’t hurt it any more than it is so go at it with a brass or even a stainless brush.

I havent had much luck with Hoppes 9 or most bore cleaners Ive tried for cleaning bad antique bores even wiith vigorous brushing. I use a pull thru method on Levers’

In Canada there is a product called Gunzilla and its the closest to a miracle cleaner as Ive used. Soaking for at least a day Horizontal seems to dissolve everything lead ,  copper , rust ,   with not much  brushing .With real stubborn rust or crud the more days soaking the better. Shooters Choice mixed with Kroil (recommended to B/R shooters by Walt Berger of Berger bullets )is  good as a second soaking solvent and storage coating . It is frustrating trying to clean some cruddy bores , but a combination of shooting jacketed bullets and soaking with these 2 solutions gives me the best results. Eventually bores even shine .Underlying pitting and corrosion are eventually exposed and sometimes not as bad as estimated. My first old gun , a 94 32-40 , bought 40 years ago had a very dark bore till about 5 years ago using Gunzilla , and I never thought it would clean up. Bore is much better than I thought now that I can see it. Not abusive like short  soak 15 minute only ammonia products , and doesnt smell volatile . May sound Hokey , but I have no stake in the company

I’ve had some good luck over the years with cleaning the bore as best as I could and then shooting about 10 rounds loaded with gas check reloads.  I got the impression that perhaps the leading edge of the gas check acts as a scraper while traveling down the bore.  Had the best results when I had a sizing die that was about .001 or .002 larger than the bore.
