Well, you did not say what powder you are using I use different solutions with different powders.
Pyrodex =Alcohol and windshield washer 50/50
777 =Windex with vinegar
Blackhorn 209 = Hoppes #9 / alcohol or Montana X cowboy bore cleaner
What ever you use be sure to oil with a good gun oil after you dry the bore as far as I am concerned the synthetic is by far the best for several reasons.
I am not up on APP powders I use them for a couple of years and throw what I had out and quit buying them, I live in a high moisture area and they were erratic to the point where it was not worth the effort.
