I have a PWS FSC556 brake. I like it. BUT, on the last baffle there is a strong build up of unburnt powder. I've used all kinds of solvents and event scrubed with a bronze bristle brush....no dice. The build up surrounds the exit hiole, and has made the surface/exit hole very uneven. Will this cause accuracy issues?

Leave it alone. It's not unburnt powder. The metal is actually damaged from the muzzle blast.
