Know Before You Buy

BL550 Reloading Machine

Questions, Answered.

What is the difference between the BL550 and the RL550C?

The BL550 is the basic version of the RL550C reloading machine. Instead of the automatic powder measure and priming systems included with the RL550C, the BL550 offers a funnel system so weighed powder charges may be poured into the case without removing it from the shellplate.

What calibers will the BL550 load?

Over 160 different rifle and pistol calibers, from .32 ACP up through .338 Lapua, .416 Rigby and .460 Weatherby - the widest variety of cartridges of any Dillon machine.

Which caliber conversion kits does the BL550 use?

The BL550 uses RL550C caliber conversion kits, which must be ordered separately. If a * appears in the caliber conversion listing, you will also need the XL Powder Die #21253.

Does the BL550 come with dies?

No. Dies are ordered separately. The BL550 functions with any standard 7/8" x 14 die set, and the removable toolhead keeps them in perfect adjustment between caliber changes.

What warranty does the BL550 come with?

Dillon offers a 30-day trial period, and if the machine breaks we will fix it free for as long as you own it.

General Information

The Dillon BL550 is the basic version of the RL550C reloading machine. Instead of the automatic powder measure and priming systems included with the RL550C, the BL550 offers a funnel system so weighed powder charges may be poured into the case without removing it from the shellplate.

The BL550 accommodates the widest variety of cartridges of any Dillon machine, from .32 ACP up through .338 Lapua, .416 Rigby and .460 Weatherby, and will produce match-quality ammunition for over 160 different rifle and pistol calibers.

A Simple Four-Step Process

  • Station 1: deprime and resize
  • Station 2: pour the weighed powder charge through the funnel
  • Station 3: seat the bullet
  • Station 4: crimp

All four operations happen without changing dies between steps.

No Adjustments

With the BL550's removable toolhead, your dies stay in perfect adjustment. There's no need to screw them in and out, even when changing calibers. The BL550 functions with any standard 7/8" x 14 die set.

Warranty

Dillon offers a 30-day trial period, and if the machine breaks we will fix it free for as long as you own it.

Ordering Notes
