This is kinda in the dumb question category. We hear about fiberglass ramrods damaging barrels, delrin rods are ok, but dirty delrin rods are not, wood can pick up dirt, steel for sure is bad unless using a bore guide. So my question is can any damage happen from using a brass bore guide at the muzzle? Would plastic be better? Or is this all overthinking 'cause the County shut down my range for a month?
