Lee Decapping Die, no cleaning or lubing of cases necessary. Even removes crimped primers, one size fits most cases. The most likely reason a pin would bend is that the user is trying to primers from Berdan casings. Berdan casings are not designed to be reloaded, only casings with crimped primers can be reloaded. Most steel and aluminum casings are Berdan casings. Another common cause of a bent pin is not placing the shell casing all the way into the shell holder.
