I have an H&K P30L with polygonal rifling. I am shooting FMJ regularly at the range. I have noticed debris building up in the barrel that is not removed when cleaning. I have been using Hoppes #9 solvent and nylon bore brushes. Speaking to my LGS, I tried a stronger solvent meant for copper residue and used a phosphor bronze bore brush. That worked better, but it still took a great deal of soaking the barrel with solvent and letting it work for some time and scrubbing to get it clean. It seems like there must be a better way.
What do you use for a good solvent that will remove copper debris with (relatively) minimal effort? How do you feel about "treatment" chemicals like Militec-1 conditioner? How about combination CLP products?
What about the use of a nylon brush? A friend told me he prefers nylon to prevent wear on the barrel over long times with frequent cleaning with bronze.
Finally, someone told me Hoppes #9 fumes are really bad and should not be used indoors. True?
Thanks again for your feedback.
