I'm allergic to hard scrubbing of guns,,,, I find if I open the rifle and tilt it down onto a rag I can squirt "Barrell blaster" (foaming cleaner) down the barrell and go back up stairs.
The next day the rag is wet and dirty and i take a patch with some hoppes 9 on it and run it through 2 times and a dry patch through 2 times i'm done.
Barrell is squeaky, shiney, clean.
