The four issues addressed by this upgrade are:
- Addition of a bearing to the case feed ram cam follower to reduce friction and eliminate the need for lubrication at that point.
- Replacement of the factory issue shell plate index detent ball with a low mass industrial bearing to reduce impact energy.
- 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.
- Addition of a bearing atop the shell plate, one that actually fits.
Adjustment is simple. Screw it in there. Leave it too low. Turn it up higher until the case feed ram just barely seats your case to the back of the shell plate, make sure the bearing is lined up right with the cam, then set the jam-nut.
