Delrin index ball for Dillon XL 650

 If you are trying to minimize gun powder spillage from the brasses during every rotation, you are the one who should be interested in this replacement for original indexing ball (Dillon 13891), which indexes shellplate. Indexing ball is made from very tough plastic which is know as Delrin. This plastic is characterized by high stiffness, high wear resistance, heat resistance, flexibility, low water absorption and a very low coefficient of friction.

The main purpose of replacing it with an iron ball is that you reduce the weight of the ball that hits the shellplate from below and thus eliminate as much as possible the shaking caused by this movement.
