Re: best bore brush
I use a nylon brush to apply copper solvent.
I use a bronze brush to scrub and apply solvent to scrub powder residue.
"If you love wealth more than liberty, the tranquility of servitude better than the animating contest of freedom, depart from us in peace. We ask not your counsel nor your arms. Crouch down and lick the hand that feeds you. May your chains rest lightly upon you and may posterity forget that you were our countrymen."-- Samuel Adams
