Build Quality, Materials, and Ergonomics
The foundation of the Dillon Precision Powder Measure 1050, RL1100 is a high-density cast aluminum housing that provides a lightweight yet extremely rigid platform. Rigidity is paramount when a measure is mounted on a press that exerts the forces required to swage military primer pockets. The most significant upgrade in the Dillon Precision Powder Measure 1050, RL1100 over consumer counterparts is the powder die. For the 1050 and RL1100 series, Dillon utilizes a heat-treated steel die with a black oxide finish. This finish provides superior wear resistance and a smoother internal surface for the powder funnel to cycle through during high-speed operations.
Ergonomics and Mechanical Advantage
Ergonomically, the Dillon Precision Powder Measure 1050, RL1100 is designed for a “hands-off” experience. Unlike manual measures that require a separate handle stroke, the Dillon Precision Powder Measure 1050, RL1100 is integrated into the press’s toolhead. The mechanical advantage is derived from the press’s linkage, which drives the powder bar across its full travel until it is flush with the measure’s body. This design ensures that every drop of a powder like Hodgdon Varget or Winchester 748 is consistent, provided the stroke is rhythmic. The volumetric adjustment is handled via a steel bolt on the end of the powder bar, allowing for minute changes to the charge volume without the need for specialized tools.
Comprehensive Setup, Calibration, and Operation
To set up the Dillon Precision Powder Measure 1050, RL1100 for success, a meticulous cleaning and calibration protocol is required.
- Initial Cleaning: Because the Dillon Precision Powder Measure 1050, RL1100 is a commercial tool, it often arrives with a light coating of preservative oil. Disassemble the unit and clean the steel powder bar and the internal housing with a residue-free solvent. Professional reloaders often perform a “polishing mod” using a fine abrasive to ensure the slide bar moves with zero friction.
- Die Installation: Screw the black oxide powder die into the fifth station (standard for RL1100) or fifth station (Super 1050) of the toolhead. Ensure the die is set to provide a proper bell to the case mouth if loading handgun calibers like 9mm Luger or 45 ACP.
- Failsafe Integration: Attach the failsafe return rod. This is a non-negotiable safety feature of the Dillon Precision Powder Measure 1050, RL1100. The rod must be adjusted so that the return spring is compressed enough to ensure the bar fully resets when the handle is pushed forward.
- Calibration: Fill the hopper with a propellant such as Hodgdon H335 or Ramshot TAC. Throw 10-15 “dummy” charges to settle the powder column. Adjust the powder bar screw and verify the weight on a high-precision scale like the Dillon Precision D-Terminator Electronic Powder Scale 1500 Grain Capacity.
- Operation: During high-speed production of 223 Remington or 308 Winchester, monitor the Dillon Precision RF1100 Auto Primer Filler Assembly if applicable, but keep your primary focus on the powder level in the Dillon Precision Powder Measure 1050, RL1100 reservoir.
Maintenance
The Dillon Precision Powder Measure 1050, RL1100 features several wear items that require attention. The “bellcrank cube” (the small white plastic square) and the “body collar sleeve” should be inspected every 5,000-10,000 rounds. If these parts show wear, the powder bar travel may become inconsistent. Keep the Dillon Precision Powder Measure 1050, RL1100 dry and free of liquid lubricants, as they will cause powder clumping.
