After days of cleaning with most methods ever published one of my rifles will still produce light blue patches when chemical bore cleaner is run through the barrel on a patch.
It's an accurate rifle, but... How clean does it have to be?
Believe me, I've tried chemicals, foam included, abrasives such as JB and Remington's. I've plugged the bore and had chemicals in 24 hours. Still light blue patches. I have not tried the electrical rod method, yet.
