The RCBS case trimmer pilots are designed with an ever so slight taper which guides the pilot into the case mount. What this does is it prevents the case from wobbling during the trimming process. The case trimmer pilot is made from steel and features a natural steel gray finish. Like with many of the RCBS products the case trimmer pistol is made in the USA.
