Here is how to remove the residue:
Buy Blue Wonder cleaner and rather than a plastic cleaning tip purchase a brass cleaning jag (about $3), the jag does a superior job of cleaning as it forces the patch into the grooves and Blue Wonder is a great cleaner.
I used to think my guns were clean then I brushed the bore with Blue Wonder and let it sit a few minutes then did a follow up cleaning using the brass jag, the patches that came out of the "clean barrel" were filthy.
Try it and you'll never go back to another cleaner and plastic tip/patch again.
You have little to lose ($3 for the jag & $6 or so for the cleaner) and a very clean barrel to gain.
