Your RL 550B has been shipped to you with the primer system installed and correctly adjusted to feed large primers. If the caliber you have selected to start with requires small primers, you must change to the small primer slide bar.
  Observe carefully how the factory-adjusted bar fits (see Figure 11). Raise and lower the platform and notice the alignment of the primer seating cup (*#13824) as it enters the platform. This adjustment is made by turning the cap screw (#14037) on the primer feed body (see Figure 12).

They are color coded for easier identification. The large ones should be used together and the small ones should be used together.

placement of the rod. Unscrew the knurled cap (#13957) and remove the large primer magazine and replace with the small primer magazine tube (see Figure 14); the plastic tip should look like the one you just took out. Replace the knurled cap.
  Wait until you’ve finished assembly before actually placing primers in the magazine.
  You will notice that the primer magazine tube tips are different colors and have an indexing ridge on the tip. The magazine tips and the primer pick-up tube tips are color coded to help identify their size. The indexing ridge is to help you place the magazine in its proper position in the primer feed body.
