A&D FZ-120i and AutoTrickler V4 Combo | Buy Precision Powder Dispensing System South Africa | 0.001g Accuracy

The A&D FZ-120i and AutoTrickler V4 combo is the gold standard precision powder dispensing system for long-range and precision rifle reloaders who demand charge-to-charge consistency that no manual trickler or beam scale can match. The A&D FZ-120i is a laboratory-grade 122g x 0.001g precision balance with internal calibration, and the MacDonald Innovations AutoTrickler V4 is a clean-slate redesigned automatic powder trickler that integrates directly with the FZ-120i to dispense powder charges at up to 50 GN/s, ramping down smoothly to within 1 to 2 grains of the target before trickling the final grains one kernel at a time to exact weight. If you are looking to buy a precision powder dispensing system in South Africa for long-range reloading, this combo is the correct starting point.

Why Precision Reloaders Choose the A&D FZ-120i and MacDonald Innovations AutoTrickler V4 System

A&D FZ-120i | Laboratory-Grade 0.001g Precision with Internal Calibration
The A&D FZ-120i is a compact, lightweight laboratory precision balance with a 122g capacity and 0.001g (approximately 0.015 grain) readability – the resolution required for consistent charge weights in precision rifle reloading. The FZ-120i uses A&D’s patented C-SHS (Super Hybrid Sensor) weighing technology for fast stabilisation and a compact footprint suited to a reloading bench. Internal calibration eliminates the need for external calibration weights and allows the balance to self-calibrate at any time, ensuring accuracy is maintained regardless of temperature changes in the reloading room. IP65-rated for resistance to dust and moisture, making it suitable for use in any environment where a laboratory balance would typically struggle.

MacDonald Innovations AutoTrickler V4 | Clean-Slate Redesign for Maximum Speed and Precision
Since the original AutoTrickler was invented in 2016, it has become the go-to solution for long-range shooters who need to measure accurate powder charges quickly. The MacDonald Innovations AutoTrickler V4 is a clean-slate redesign – starting with the idea of a single assembly without needing manual adjustments, every part, every feature, and every detail was rebuilt from the ground up. The V4 uses a large tube with deep spiral grooves — inspired by an auger — that pours bulk powder at rates up to 50 GN/s, ramping down smoothly to within 1 to 2 grains of the target before the fine trickle takes over for kernel-precise final dispensing. No manual trickler or drop tube can match this combination of speed and precision.

Works with All Common Reloading Powders | Ball and Stick
The MacDonald Innovations AutoTrickler V4 handles the full range of reloading powders that South African precision reloaders use – fine ball powders like CFE223 and H335 as well as large kernel powders like N570 and H50BMG. The dual-tube auger design with independently controllable large and small tubes allows the system to be optimised for different powder types, providing consistent performance whether you are loading 6mm Creedmoor with Varget or .338 Lapua with N570.

Integrated Electronics | One Cable, No Manual Adjustments
The MacDonald Innovations AutoTrickler V4 features integrated electronics and motors with fixed cabling – no loose wire management. One cable connects the AutoTrickler to the A&D FZ-120i scale with 20 AWG wiring, with strain relief on both ends and an in-line connector for easy disconnection. The acrylic panel and silicone pads keep the assembly stable and quiet on the reloading bench. The electronics module is replaceable if necessary, and all commonly replaced wear parts are user-serviceable.

Hopper Design | Clean Powder Handling and Easy Changes
The hopper incorporates a rotating valve so it can be removed easily and has a flat bottom so it can rest on the bench while holding powder. When in use, the hopper is positively locked into the housing and blocks the powder reservoir from opening while the valve is open, keeping spill risk low. Changing powders between loading sessions is clean and straightforward — tilt the unit back, slide up the window, and pour remaining powder back into the hopper.

What the Combo Includes
The MacDonald Innovations AutoTrickler V4 kit includes a glass cup, V4 centering tray, V4 funnel, 2x V4 windows, V4 timing belt (small tube), V4 timing belt (large tube), and the AutoThrow powder hopper. The A&D FZ-120i includes the balance, power adapter, and calibration documentation. The power adapter is required to run both the scale and the AutoTrickler motors simultaneously from a single power source.
