4th Generation Dillon Primer Track Bearing Plate 16 gauge 304 series stainless steel. Laser cut on a 5,000 watt C02 Mitsubishi Laser 2D cutter. Will fit 450, 550 and 550B Dillon Presses. The ball bearing is a rubber sealed bearing to keep out dust and primer dust. This plate has been developed to solve the primer slide binding/sticking. Two separate forces are pushing and pulling on the primer slide simultaneously while it moves towards the primer magazine to pick up a primer. First-When the primer slide (14281) is moving back into the primer housing/shield (20263) to pick up a primer, the primer slide return spring (13928) is pulling the bottom of the primer slide causing it to tip, which allows debris to get under the primer slide, which causes binding. Second- The primer slide is being pushed towards the primer housing on the right side by the operating rod (13869) to pick up a primer. This causes the primer slide to bind/rotate/twist in the channel of the primer housing/shield (20263). When it's fully retracted into the primer housing, is when it's mostly likely to bind up and get stuck. Thousands have been sold in the United States and worldwide. Happy customers have reported thousands of rounds loaded without the need to disassemble the priming system for cleaning. **For Dillon 450 users, I have received feedback from several DL 450 owners that it fits and functions correctly. I have not personally tested it on a DL 450. Included in the package: an Allen wrench, bearing, and detailed directions. Design has been Copyrighted and a patent pending
