All cylinders are hand reamed to uniform dimensions with a quality cutting oil, standard and custom order Manson throat reamers and pilot bushings. The cylinders are then cleaned and given a concentric brushing, leaving each throat a smooth even brushed finish.
After being cleaned and de-oiled, blued cylinders then have their throats cold blued. The cold bluing is meant as a temporary rust protectant until the firearm is used again. Once the revolver sees regular use the throats will season from the heat and carbon.
No. Polishing a cylinder throat to a mirror finish does nothing to improve accuracy, but greatly increases the chances of creating flared throat leads and mouths. It's temporary cosmetics.
