PART# 29023 3/8/2010 • LEAD WARNING: Be sure to have proper ventilation while handling lead components or when shooting lead bullets. Lead is known to cause birth defects, other reproductive harm and cancer. Wash your hands thoroughly after handling anything made of lead. • LOADS AND LENGTHS: Avoid maximum loads and pressures at all times. Use only recommended loads from manuals and information supplied by reliable component manufacturers and suppliers.
PART# 29023 3/8/2010 reloading bench is no place to get into a hurry. We have done everything we know how to make your machine as safe as possible. We cannot, however, guarantee your complete safety. To minimize your risk, use common sense when reloading and follow these basic rules. • REMEMBER: If your machine does not perform to your expectations, or if you are having technical difficulties, give us a call. Mounting the DILLON BFR for use.
PART# 29023 3/8/2010 PARTS DIAGRAM This is the basic layout of the machine. Noted above are the primary sub assemblies which are detailed in the following pages. Once your machine is mounted you will need to install the “Spent Primer Catch System” on to your machine. Start by removing the four mounting screws and nuts from the assembly (Part# 29009 and 16340). Assemble it onto the front left side post on the machine as shown in the diagrams below.
PART# 29023 3/8/2010 PRIMER CHUTE ASSEMBLY NOTE: When adjusting the primer chute assembly, with the platform at the top of its stroke, the chute should be in line with the spent primer hole of the platform as shown at right in “DETAIL A” The chute should only make contact with the platform and never touch the main shaft (PN: 19827) at any position.
PART# 29023 3/8/2010 TO BEGIN RELOADING The Dillon “Big Fifty Reloader” or “BFR” is semi-progressive four-station press. The press can either be set up to rotate in a clockwise or counter-clockwise direction allowing the user some flexibility in their reloading process. As offered by the entire line of Dillon products, the machine has the capability of interchangeable tool heads to allow the user to have multiple setups for the machine.
PART# 29023 3/8/2010 Choosing your dies The Dillon BFR will perform well with any manufacturer’s standard 1½”-12 UNF threaded dies. Be ware that many 50 BMG dies currently available are for use in single-stage presses, and may have a sharp lead in, which may not be very forgiving in a progressive press. The Dillon 50 BMG full length carbide sizing/de-priming die is manufactured to minimum tolerances.

PART# 29023 3/8/2010 PRIMING The 50 BMG priming system is a departure from typical Dillon priming systems. It has been our experience that a magazine of No. 35 primers is a very dangerous prospect due to the comparatively massive amount of explosive contained therein. So we are introducing our 50 BMG “Top of Toolhead” primer seater. This configuration allows for easy access for manual “one at a time” loading of primers, while taking full advantage of the final cam portion of the stroke to seat the primer.

PART# 29023 3/8/2010 Dillon 50 BMG Case Trimmer TO OPERATE: You will need a pair of calipers to set the trim die properly. THIS DIE IS NOT DESIGNED TO SIZE THE CASE AS IT HOLDS THE CASE NECK ONLY. For best results you need to clean, size, and lube your brass before trimming. Place a clean, sized, and lubed case into the station for the trimmer and raise the platform. Install the trim die (without the trim motor) into the Toolhead on your reloading machine.
