    What are the locator buttons in a dillon 550b conversion kit used for? I installed the shell plate and rod but don't know what these are for.

    They keep the cases in the shell plate.

    And keep the cases lined up under the dies.

    "rod" = powder funnel?

    The locator buttons are part of the solution to the problem of a varying cartridge head diameter. The shellplate "cutouts" are the other part. Together, these two minimize any side motion in the brass that might cause misalignment when the ram is lifted toward the dies in the toolhead.

    If you look closely, you can see a number stambed on each locator button. That number is supposed to match the number of the shellplate in use.

    (While they're a little bit expensive, Dillon sells toolhead stands that have three holes and a slot to store the shellplate and locator buttons that match the extra toolhead you can set up for each cartridge you load...)

    Not quite right. I go from 9mm to .40 by switching the buttons. The shell plate is the same.The complete listing of shell plate and locator buttons is at the end of the 550 manual under caliber conversion kits.

    Oops.

    Well, you know what happens when you assume...

    I have this really large collection of shellplates and buttons ( :) ) for .45 ACP, .243 Win, .30-06 Sprg and .44 Mag. They first three use shellplate 1, locator buttons 1, and .44 Mag uses shellplate 4, locator buttons 4. So I assumed they were numbered to match.

    I looked at the complete listing...wow! There are lots of combinations. Apparently you have to refer to this table to keep everything straight, if you reload a lot of different cartridges. Either that or just keep the shellplates and buttons together on toolhead stands and don't mix them up.

    Also allows you to remove a cartridge at the charge or seating station when you have an upset in the cycle.

    Loadedround, can you tell me if I can use my Dillon 9mm conversion plate/kit on .380 loads? I haven't tried, just thought you might know.

    Did your press come with a manual or did you buy it used?

    If you need one you can download it from Dillon's site here. The manual has pictures and illustrations of where they go and this description of what they do.

    The manual linked above has a listing of shell plates, locator buttons, and powder funnels for the different conversion kits. The .380 and 9mm use different plates, but the same locator buttons and powder funnel. All you need to buy is a shell plate (# 13684) to be able to reload both cartridges.

    There's another use for locator buttons that hasn't been mentioned.

    When you set something down on your reloading bench and can't find it 3 minutes later, if you'll just press one of those buttons. A very polite, well dressed young woman in a black form fitting dress and a Kimber (finger off the trigger) will step out of the Dillon calendar and help you locate it.

    Just don't get over zealous, throw 3 primers on the floor, and then press the locator button. She already wised up to that one. She mentioned something about crawling around on RC's floor for an hour one afternoon.

    Nice Kimber, though. :D

    I knew there was another reason to like my Dillon press, besides reliability and ease of use. I'd heard of their outstanding customer support, and this proves it!

    ...just where in the manual does it describe how to use these locator buttons again? :)
