Dillon 550C System Builder

The Dillon RL550C is the most versatile reloading machine in the Dillon Precision Products line.  It will accommodate the widest variety of cartridges from 32 ACP up to 338 Lapua, 416 Rigby, and 460 Weatherby.

Build your ultimate reloading setup here. Choose from the press, the dies and any accessories you need. Just work through the steps and we will guide you through every choice. No incompatibilities, no problems!



Auckland Only – setup and basic configuration of your press – allowing for two hours time.


The RL 550B and the XL 650 presses do not come with Dies.

Dies are ordered separately for both the 550 and the 650. You can, however, use any manufacturer’s standard 7/8″ x 14 dies in a 550 or a 650 press.

Progressive Dies, Non-Progressives Dies

With the RL 550B’s 4-station Toolhead, and the XL 650’s 5-station Toolhead – both machines are designed to seat the bullet and taper crimp the round in separate stations. Chances are your non ‘progressive’ dies seat & crimp in the same die.

The Redding Upgrade

We would strongly suggest you consider upgrading to the Redding Dies. In the greater scheme of things, the upgrade is a small cost and it ensures you are setting yourself up with the best, right from the start.

Dies DO NOT come with the 550 or the 650 press.

The calibre selection for either press includes the Caliber Conversion Kit for that calibre.

Both the RL 550B and the XL 650 press come with:

  • Primer Early Warning System (Electronic)
  • Automatic Priming System for small and large primers
  • Toolhead
  • Automatic Powder Measure System inc. small (pistol) and large (rifle) powder charge bars.
  • Akro Bin (catches loaded ammo)
  • Caliber Conversion Kit: All the caliber-specific items for the press, except Dies
  • 1 Small and 1 Large Primer Pickup Tube
  • Standard (not ball-end) hex key set (allen wrenches)

Have a read up on some of our recommended upgrades and add-ons to make your reloading more efficient, more accurate, more fun!

The reason you are likely looking at a progressive press in the first place is due to speed – speed being a combination of technology and ergonomics. While there are several options within the Dillion Family itself, we have looked beyond, to specialist, boutique suppliers that will enable you to hotrod your Dillion.

Inline Fabrication Ultramount System

IMG_2798Unless you are particularly short, or, set up the entire system to work from a sitting position, the standard press mounted to a table, is likely to actually be far too short to be the most ergonomic setup for you. Certainly, at 6-foot-1-andabit, the standard setup was too short for me to comfortably use for any decent amount of time. So the first thing to do is get it lifted up to a better working height.

Inline Fabrication makes a series of mounting systems for all manner of presses. Lifting the unit up and providing more footprint (meaning more stability) – the mounts also provide the space to start adding on other accessories to really ramp up your reloading.

Inline Fabrication makes their mounts to a higher standard than the Dillion Ones, and, should you change in the future – the top plate can be swapped out for a new plate, or, install the quick-change system and save bench space!

Inline Fabrication Input/Output Bins

DBLbultrayOnce you have the Ultramount in place – you can start bolting bins on to bring your working space closer together. The dual bin system consists of a bin in front for empty cases, a bin behind for completed bullets and a modified ramp to direct finished rounds to the rear bin.

This significantly reduces the amount you need to move your hands to grab a new case to put into the machine. Speeding the process up considerably.

Inline Fabrication Double Bullet Tray

Much like the Input/Output Bins – the Double Tray is designed to get the projectiles closer to the process – minimising hand movements and increasing ergonomics. Twin bins give you one bin for projectiles and another to keep tools and parts handy.

Inline Fabrication Ergo Roller Handle

Finally, replace the standard handle with a roller model. Not only easier on the hands, but the angled shaft also makes the stroke easier on the back.

Primer Flip Tray

Flips 100 primers at a time, “cup side up,” so they are ready to be picked up by the:

Primer Pickup Tubes

All Dillon machines come with one small and one large Primer Pickup Tube, so I highly recommend buying a 4-pack of extra Pickup Tubes (in the appropriate size) when buying a press. Both small and large Primer Pickup Tubes hold 100 primers.

Bench Wrench

It has a 1″ open-end wrench on one end, which fits the lock rings on Dillon’s Dies (only), and a 7/16″ box-end (fits the Powder Measure) on the other. It’s super handy, especially in the tight confines of a four or five-station Toolhead.

The Bench Wrench is also available with a five-pack of one-inch Dillon Die Lock Rings, which allows you to use Dillon’s Bench Wrench on your “other brand” Dies. Note: You do not need the extra Lock Rings if you buy Dillon’s Dies.

Toolholder w/ 1″ Bench Wrench and 5 ball-end Hex Keys

The newly introduced Toolholder includes a 1″ Bench Wrench a 5 ball-end Hex Keys, and the Toolholder mounts on the back of the machine.

Maintenance/Spare Parts Kit

Will save you the “down time” waiting for Dillon to send (warranty) a broken small, spring, clip, or plastic part. You might think, “Why should I buy a Spare Parts Kit?” “Does that mean parts will start breaking right away?” Absolutely not. I think of the Spare Parts Kit like a Bullet Puller: buy it and forget about it. Then at some point if you need it down the road you’ll be real happy you have it. The Maintenance/Spare Parts Kit is the Spare Parts Kit plus lube. Get the version with lube. The machine will love you for it.

Powder Scale

p_100-013-600_1An accurate powder scale is a necessity – to both setup and check the powder throw coming off the Dillion. Even once running, I would still stop to check regularly to make sure nothing has changed on you expectedly.

We have the awesome GemPRO 250 – for the price, it’s hard to beat. Make sure you read up on our setup suggestions to get the most out of it. A little knowledge goes a long, long way.


You will also need to measure and set the overlength of a loaded cartridge as well as checking the taper crimp. While I am sure the purists will cringe, our Mitutoyo Digital Verniers are quick, accurate and the last pair of verniers you will ever need to purchase.


Case gauge(s)

CG45-100-2Running each and every cartridge you make through a gauge gives you a final check on sizing, and means another visual check to ensure nothing is untoward with your completed loads. We have single units, or, for bulk loaders, Shockbottle Trays that will take up to 100 at a time and quickly dump them into your cartridge cases.


A dust cover

We actually include these will the units, that’s how  important we feel it is to keep the units dust and contaminate free.

Yes, and no.

Carbide Dies are often sold on the basis that you don’t need to lube your brass when using them. I would still lube the cases though. Just try with and without and you will realise, even if you don’t, it makes things a lot smoother. Pistol, straight wall, you might even get away with no lube at all. Rifle – you will still need to lube.

You will, however, be able to use much less lube, which is less left on the brass – and, depending on your process, might mean you don’t need a second run in the polisher after prepping brass for .223 (for example).

Also, we sell, and recommend the Redding Titanium Carbide Dies. Again, better materials used, to a better tolerance.

They cost more. But not much more when taken in the context of the system you are purchasing.

Also, the carbide will last forever.

For each additional calibre, adding a calibre to an RL 550B Requires:

  • Dies (either Dillon’s or Redding)
  • Caliber Conversion Kit  (Inc.: Shellplate/Locator Buttons (Qty. 3)/Powder Funnel)

AND, either a:

  • Deluxe Quick-Change Kit (includes Powder Measure)
    or a:
  • Toolhead & Powder Die (no Powder Measure)

The Deluxe Quick-Change Kit includes a Toolhead, Toolhead Stand, Powder Measure and Powder Die. Since the Deluxe Quick-Change Kit includes the Powder Measure, when changing calibres, you will be able to leave the Powder Measure on the Toolhead along with the Dies, adjusted to throw the exact charge for a specific calibre. In other words, when changing calibres, you can change the entire Toolhead assembly in a couple seconds, without having to move, adjust, or re-calibrate anything. Just do it. Your brain and your spare time allocation will thank you for it.




The Dillon 550C

Reloading with Dillon’s RL 550C is Easy as 1-2-3!

Most shooters realise that reloading is the most economical way to enjoy their sport, but many shooters are unaware of just how simple it is to reload. In fact, Dillon’s RL 550C is the easiest progressive loader in the world to learn to reload with. How can we make that statement? Simple. Since all of the reloading steps are performed with a stroke of the handle, there is less to remember (or forget) than with an old-fashioned single-station press. Skeptical? Just watch this short video to see how easy it really is.

No Adjustments

Of all the steps in reloading, the adjustment of the reloading dies is the most critical. With the Dillon RL 550B’s removable toolhead, your dies will stay in perfect adjustment. There’s no need to screw them in and out even when changing calibers! The RL 550B functions perfectly with any standard 7/8” x 14 die set. There’s less to go wrong, less to remember.

It’s Your Choice

You can struggle along with a slow, cumbersome single-station press with all its adjustments, changes and secrets, or make your life easier with a progressive RL 550C. Our warranty is simple: If it breaks, we’ll fix it FREE for as long as you own it.

Rifle and Pistol

The Dillon RL 550B will produce match-quality ammo for over 160 different rifle and pistol calibers.


The RL550C has a manually indexed shellplate making it easier to master the various steps of reloading. Manual indexing also gives the operator greater control over each individual step in the loading process. Calibre changes are simple and require fewer parts than other machines which makes it less expensive to convert to another cartridge.

The basic 550 includes:

  • Machine with shellplate kit (shellplate, locator buttons, powder funnel) in the calibre of your choice.
  • Powder measure with standard large and small powder bars (small installed). The small bar throws from 2.1 to 15 grains of powder. The large bar throws up to 55 to 60 grains of powder.
  • 1 priming system with large and small priming parts.
  • 1 large and 1 small primer pick up tube
  • Low Primer Alarm
  • 1 toolhead
  • 1 powder die
  • 1 loaded cartridge catch bin
  • 1 written instruction manual
  • 1 set of standard Allen wrenches


You will also need (at a minimum):

  • Conversion Kit, to suit the calibre your wish to reload
  • Die set (dies are not included with the base unit)
  • Powder scale
  • Reloading Handbook
  • Dial calliper
  • Primer flip tray
  • Case lube (for bottleneck cartridges)

I suggest that you also get:

  • Extra primer pick-up tubes, if loading more than 100 – 200 rounds per sitting.
  • If you are loading more than 500 rounds per reloading session, then the RF-100 Electric Primer Filler is an accessory well worth considering.
  • A machine cover to keep the unit dust free.

To change calibres, you will need:

  • A Die set for the new calibre.
  • A Shellplate Conversion Kit.
  • If you have the optional electric casefeeder you may need a different casefeed plate.

If you want to leave your dies pre-set, you’ll need:

  • Toolhead (SSL PLU #30036)
  • Powder die (SSL PLU #30188)

OR to make the change quick and easy, the 550 Quick Change (SSL PLU#30261), which includes a powder measure, powder die, toolhead and a toolhead stand. This allows you to leave your dies and powder charge set up and dedicated to a specific cartridge for faster, easier calibre changes.
