Gunslick Foaming Bore Cleaner (12-Ounce) : Amazon.com : Sports & Outdoors is the simplest and most effective cleaner I've found to date, and the Amazon listing is the simplest and cheapest way I've found to get it.
I can appreciate your disappointment with the Hoppe's #9 Copper Solvent. It tends to be on the gentler side of copper solvent choices, and really isn't ideal for removing carbon fouling. The Gunslick Foam will work much better, and much more easily.
There may be some sense in easing up on your cleaning regimen. A virginal-clean barrel needs some shots to establish a stable fouling condition, and that's the state where load development is done and is effective.
If you don't clean between shootings sessions, it can pay to do some corrosion prevention for longer periods of downtime. I will oil my bore for longer downtime if I'm skipping the cleaning, then patch it back out just before shooting again.
