Cleaning a shotgun barrel?

My shot gun barrel has a residue of molten plasctic. I've scrubbed using a brass brush, used nitro slovent and gunslick foam. But I still have some pesky plastic residue. Are there any suggestions as to what product will disolve it? Thanks in advance.

I had a similar situation with a rifled slug gun. I ran a swab with acetone down the bbl a cpl of times and then and oiled patch. Seemed to smarten it right up. Groups came back together.

Thanks Cat & Abe...I have some Acetone. I'll try that first.
