I've used gallons and gallons of this stuff. I used to get it free. Still have a bunch left over. Any time the ammunition might have even a chance of being corrosive, RBC is the stuff to use, as immediately after firing as practical. (The primer in a tank gun round contains about 1500 grains of black powder, which is one reason the Army still uses RBC.)
Cleaners like Hoppes #9, which contain ammonia are hard on nickel finishes as they attack the copper layer beneath. They are good at getting after jacket bullet fouling.
