Sounds almost too clean if the patch is squeeky and comes out clean.
I use foaming cleaner, Wipeout, KG, gunslick etc until the patch stops coming out blue, then clean the solvents out of the bore with an alcohol patch. Then 1 patch with light oil to protect and lubricate the bore then 1 dry patch to remove the excess oil.
Just be sure to remove the excess oil, had a guy blowing primers because he run a sloppy wet patch with motor oil on it and left the excess oil in the bore.
