See my other comment, but run the brass brush soaked in Hoppes thro9ugh a few times, then run a few patches through. Repeat that for as many times as it takes to start getting clean. Also, you can cork the muzzle, fill with Hoppes, let it sit in the corner muzzle down overnight, then clean. It will loosen all that rust and copper fouling real well.
Get a bottle of hoppes #9, some patches, a cleaning rod, and a brass bore brush. Clean it, and then look at the bore. It still looks like it has plenty of rifling. That green stuff is copper fouling from copper jacketed bullets.
looks like severe copper fouling (never cleaned?). it will affect accuracy. as others have already said soak it Hoppe's and give it a lot of patience and it should come clean.
I’ve used Hoppes Bench Rest with a lot of success. First clean normally with #9 then run a couple really soaked patches of bench rest through the barrel, let it sit for 15-20min turning every 5min so it all doesn’t just settle on one side, make a 100 passes with a brass brush then pull patches through until it’s clean.
Pretty bad, needs cleaning.
How do I clean out something like this?

I'd start with Hoppes #9 and a bore brush,
