    General Information:

    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. Caliber changes are simple and require fewer parts than other machines which makes it less expensive to convert to another cartridge.

    Reloading With the RL 550C is Easy as 1-2-3!

    Most shooters realize 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 the video in the video tab 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 RL 550C’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 550C 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. If you’re thinking about a competitor’s reloader, before you put your money down, consider this: Dillon will let you try the RL 550C for 30 days. If it doesn’t live up to our claims – or your expectations – return it. We’ll refund your money. Our warranty is simple: If it breaks, we’ll fix it FREE for as long as you own it.

    Rifle and Pistol

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