Used Hoppes for 20 years, still do on some parts, but 6 months ago I bought a can of Gun Slick Foaming Bore Cleaner. This stuff is AWSOME! Comes with a 3" flexible clear rubber tube attached. Just jamb the tube into your chamber and push the button until you see with foam oozing out of the muzzle. The foam fills and saturates and lands and grooves in your barrel.
Wait 5 minutes, brush it 4 to 5 times, them a run a patch till it comes out clean.
$3.00 buck a can and I've gotten at least 20 clean barrels out it.
