Dillon Precision XL 650 Premium Performance Improvements Kit
Hello all, and thank you for your interest. What I have here are the necessary components required to smooth the overall cycling of the Dillon XL 650 in order to reduce powder spills, increase production and keep the press clean. The four issues addressed by this upgrade are: 1. Addition of a bearing to the case feed ram cam follower to reduce friction and eliminate the need for lubrication at that point. 2. Replacement of the factory issue shell plate index detent ball with a low mass industrial bearing to reduce impact energy. 3. Replacement of the factory issued shell plate index detent ball spring which has the ideal level of pressure to engage the detent ball into the shell plate. 4. Addition of a bearing atop the shell plate The premium kit has the same 4140 shaft with the bearing, but is professionally blackened. This smooths out the shell case ram and eliminates grease at that point. The Phenolic industrial grade bearing detent ball absorbs shock and is 1/5 the weight of the steel ball. The Music wire coil spring is the exact correct tension to index the shell plate without snap, and my solid oil-lite bronze shell plate top bearing smooths the drag and works without modification of the factory payoff spring
