Maybe someone can shed some light here.
I have a PPC barrel with a few hundred rounds through it. My usual cleaning regimen is to run a few wet patches with Shooters Choice through the barrel then a bronze bore brush through the barrel for a few strokes followed by a wet patch repeating until the wet patch is clean except for a little blue from the brush. I then run two dry patches through the barrel folloowed by several strokes of an oiled patch, then pushing a dry patch through.
I find that the oiled patch picks up something in the grooves. I have seen this to a much lesser extent before on other barrels but not like this.
Below from left to right is the patch after the last bronze brush series. Then a wet patch run back and forth about ten times.
Followed by the oiled patch run through about ten times and the pushed through dry patch.
