Dillon Precision
The most versatile progressive. Four stations and manual indexing load up to 500 rounds per hour across more than 160 cartridges, and because you advance the shellplate by hand, caliber changes are the fastest and cheapest of any Dillon.

The Dillon RL550C is the progressive for the reloader who loads many calibers rather than one in bulk. Its four stations index by hand, which sounds like a downgrade from auto-indexing but is the source of its versatility: manual indexing means the shellplate, toolhead, and powder die swap as a unit, and the machine supports more than 160 pistol and rifle cartridges from .32 ACP to belted magnums. A reloader who runs 9mm, .223, .308, and .45 ACP changes between them faster and cheaper on a 550 than on any auto-indexing press. Output still reaches about 500 rounds per hour once you settle into a rhythm. Dillon backs it with the no-questions lifetime warranty that built the brand, and the machine is direct-only through Dillon and the Dillon Amazon storefront.
