A powder trickler is one of the simplest tools in the precision reloader’s workflow – a tube with a worm gear at the bottom that drops individual powder kernels one at a time onto a scale pan. The concept has not changed in decades. What separates a good trickler from a frustrating one is the quality of the worm gear, the smoothness of the tube rotation, and the height of the output tube relative to a standard powder scale pan. The RCBS Powder Trickler 2 addresses those factors with a design update over RCBS’s original trickler, offering a height-adjustable output tube, a smooth-turning knob, and a sturdy base that stays put on the bench during use.
At a street price around $25-35, the RCBS Powder Trickler 2 sits in the practical mid-tier of this accessory category – more refined than a no-name budget trickler, less expensive than purpose-built competition accessories. RCBS built its reputation on durable, workmanlike tools aimed at serious hobby reloaders and semi-professional production operations, and the Powder Trickler 2 fits that profile. It is a mechanical device with no electronics, no batteries, and no moving parts beyond the worm gear and knob. The failure modes are simple and the service life is long.
The trickler pairs naturally with any balance beam or digital powder scale – the RCBS M500 Balance Beam Scale, the RCBS Rangemaster 2000 Digital Scale, or the Lyman Accu-Touch 2000 – in a workflow where a powder measure throws a slightly light charge and the trickler brings it to exact weight. It is a component tool rather than a standalone system, and understanding that context is essential to evaluating whether it belongs on your bench.

The Worm Gear Mechanism and Why Design Execution Matters
Every manual powder trickler uses the same fundamental principle: a worm gear – also called an auger – sits at the bottom of a powder reservoir tube. When the operator turns the knob, the auger rotates and advances individual powder kernels along its thread, dropping them from the output tip one or a few at a time onto the scale pan or into the funnel below. The precision of the trickle depends entirely on how well that auger is machined and how smoothly it turns.
The RCBS Powder Trickler 2 uses a metal auger rather than a plastic one. This matters because plastic augers wear at the thread crests over time, gradually widening the channel between auger and tube wall and allowing multiple kernels to drop simultaneously instead of singly. A worn plastic auger produces clumps rather than individual kernel drops, which defeats the purpose of trickling. The metal auger in the RCBS Trickler 2 maintains its thread geometry through extended use. Reloaders who have run the previous RCBS trickler model for ten or fifteen years without replacing the auger are a reasonable indicator of how long a metal-geared design lasts under normal use.
The height-adjustable output tube is a meaningful improvement over fixed-tube trickler designs. Scale pan height varies between different scale models. A trickler whose output tube is fixed too high drops kernels from a distance, causing them to bounce off the pan and land on the bench – a frustrating source of charge weight error. A tube set too low contacts the scale pan and introduces vibration that affects the scale reading. The RCBS Trickler 2’s adjustable tube lets the operator set the output tip 1-2mm above the scale pan, which is the correct position for controlled kernel placement without scale interference.
The knob design affects how many kernels drop per turn. A coarse knob that advances the auger aggressively is useful when trickling from several grains below the target weight. A fine-movement knob is needed for the last 0.1-0.2 grains. The RCBS Trickler 2 is calibrated for moderate advancement per turn – not as fine as a dedicated competition trickler, but controllable enough for the precision reloader who is working toward 0.1-grain repeatability on a quality digital scale.
Build Quality and Design
The RCBS Powder Trickler 2 is a plastic-bodied tool with a metal auger and a weighted base. The plastic body is sturdy enough that normal bench handling does not crack or deform it, and the base is heavy enough that the unit does not slide or tip when the operator turns the knob one-handed. The tube is clear or translucent on most production runs, which lets the operator monitor powder level without removing the tube from the base.
The output tube adjustment mechanism is a simple friction collar or locking ring – the tube can be raised or lowered and locked at the desired height. This adjustment is set once per scale combination and rarely needs to change unless the operator switches between scale models. The adjustment range covers the common scale pan heights from major manufacturers.
The knob is a ribbed plastic dial that provides adequate grip for one-handed operation. It does not have the machined aluminum feel of higher-end tricklers, but it turns smoothly without binding and does not develop slop with use. Turning speed affects how many kernels drop: a slow, deliberate quarter-turn drops one to three kernels of most ball powders; a faster half-turn may drop five to eight. Learning the cadence for a specific powder takes one session.
One design note worth stating directly: the RCBS Powder Trickler 2 is not designed to be mounted in a fixed position over a scale pan. It sits on the bench beside the scale and the operator moves the scale pan or funnel under the output tip. Some competing products offer mounting brackets or fixed-position bases that keep the trickler aligned with the scale. The RCBS design requires the operator to position the output tip over the scale pan each time, which adds a small step to the trickling workflow. This is a minor ergonomic point, not a functional limitation.
Setup and Operation
Setup requires only filling the tube with powder and setting the output tube height. To set height, place the scale pan under the output tip and lower the tube until the tip is approximately 1-2mm above the pan surface. Lock the height collar. This prevents kernel bounce while keeping the tip clear of the pan. If the trickler is being used to drop kernels directly into a funnel seated on a case mouth, set the height to clear the funnel receiver without requiring the operator to hold the trickler.
Fill the tube to no more than two-thirds capacity on the first session to confirm the powder flows freely through the auger without bridging. Some very coarse extruded powders – Hodgdon H1000, Hodgdon Retumbo, Alliant Reloder 33 – can bridge across the tube diameter if overfilled. Ball and short-grain powders fill and flow without issues.
The standard workflow pairs the trickler with a powder measure and scale. The Lyman Brass Smith Powder Measure or any conventional measure throws a charge set to drop 0.3-0.5 grains below the target weight. The thrown charge goes onto the scale pan. The operator then turns the RCBS Trickler 2 knob to advance individual kernels onto the pan until the scale reads the target weight. Remove the pan, transfer the charge through a funnel into the case, and repeat.
With a digital scale like the RCBS Rangemaster 2000 or Hornady M2 Digital Scale, the workflow benefits from a brief stabilization pause after each trickle increment – digital scales with fast response times can flicker between readings during a trickle, and waiting one to two seconds after each kernel drop gives the reading time to settle. Balance beam scales like the RCBS M500 or Hornady Balance Beam Scale require watching the beam rather than a digital readout, and the trickle pace is set by how quickly the beam settles.
Cleaning the trickler between powder changes is good practice. Different powders have different densities and kernel geometries, and mixing them in the tube produces unreliable auger advancement. Empty the tube, invert it, and tap it against a bench pad to clear residual kernels. A small brush run through the tube clears powder dust from the auger threads.
Where It Fits – Use Cases
Precision rifle load development is the primary application. A handloader working up loads for 6.5 Creedmoor, 308 Winchester, 6mm Dasher, 6.5 PRC, or 7mm Remington Magnum with extruded powder needs a trickler to reach 0.1-grain charge precision that a volumetric powder measure cannot achieve alone. The RCBS Powder Trickler 2 handles this workflow reliably at a price that does not significantly increase the cost of a starter precision rifle setup.
Any reloader who owns a quality powder scale but not an automated dispenser benefits from a trickler. The RCBS ChargeMaster Supreme and Frankford Arsenal Intellidropper 2.0 incorporate both scale and trickler functions in a single automated unit. But for the handloader who already owns a quality scale and wants to add trickling capability without purchasing an automated system, the RCBS Trickler 2 adds that capability for $30 rather than $300.
RCBS equipment ecosystem users get the natural advantage of brand-matched tooling. A handloader running an RCBS Rock Chucker Supreme single-stage press, RCBS dies, and an RCBS scale has a practical reason to stay within the brand for accessories – consistent design language, known compatibility, and a single customer service contact for any issues.
High-volume pistol loading is where the manual trickler is least useful. Trickling individual kernels onto a scale for every case of a 500-round 9mm Luger session is impractical. Ball powder pistol loads are best handled with a volumetric powder measure and an occasional scale check rather than per-round trickling. The trickler belongs in a precision rifle workflow, not a production pistol workflow.
Competitive Analysis
RCBS Powder Trickler 2 vs. Frankford Arsenal Powder Trickler: The Frankford Arsenal trickler is the most direct price-tier competitor, available at a similar street price and aimed at the same practical reloader market. Frankford Arsenal’s version has been well-reviewed for basic function and availability at major retailers. The RCBS Trickler 2’s metal auger is generally regarded as more durable over the long term than Frankford Arsenal’s plastic auger, and the RCBS output tube adjustment range is considered more flexible. The Frankford Arsenal trickler is a capable option at the same price; the choice often comes down to brand preference or which is in stock. Choose the RCBS Powder Trickler 2 if long-term durability and RCBS ecosystem fit are priorities. Choose the Frankford Arsenal Powder Trickler if it is available at a lower price or you prefer Frankford Arsenal’s broader product line.
RCBS Powder Trickler 2 vs. Lyman Brass Smith Powder Trickler: The Lyman Brass Smith Powder Trickler is another direct competitor at a similar price, designed as part of Lyman’s Brass Smith case prep ecosystem. It pairs naturally with the Lyman Brass Smith Pro Funnel System and Lyman scales. Build quality between the RCBS and Lyman units is comparable. The Lyman trickler benefits from Brass Smith ecosystem integration; the RCBS trickler benefits from RCBS brand integration. For a brand-agnostic buyer, both are sound choices at the same price point. Choose the RCBS Powder Trickler 2 if you run RCBS equipment. Choose the Lyman Brass Smith Powder Trickler if you run Lyman Brass Smith case prep tools and want matched components.
RCBS Powder Trickler 2 vs. RCBS ChargeMaster Supreme: These are not competing products – they are different tiers of the same workflow. The ChargeMaster Supreme is a fully automated scale-and-dispenser system that weighs every charge electronically to within 0.1 grains without manual trickling. It costs approximately $380-420. The RCBS Trickler 2 is a manual accessory for a handloader who already owns a separate scale. A reloader who spends significant time at the bench loading precision rifle ammunition will recoup the ChargeMaster’s price difference in time saved over a few hundred sessions. A reloader who loads 50-100 rifle rounds per month will find the trickler-and-scale combination adequate without the automated system cost. Choose the RCBS Trickler 2 if you load moderate volume and already own a quality scale. Choose the RCBS ChargeMaster Supreme if you load high volume precision rifle ammunition and the cost of per-round manual trickling in time and attention justifies the investment.
RCBS Powder Trickler 2 vs. RCBS Matchmaster Digital Scale and Dispenser: The RCBS Matchmaster is an automated scale-dispenser combo in the ChargeMaster category – it automatically drops and weighs charges to high precision without manual operation. Like the ChargeMaster comparison above, this is a different tier of tool rather than a direct competitor. The Matchmaster targets the serious precision rifle reloader who wants automation; the Trickler 2 targets the moderate-volume reloader who wants controlled manual trickling without automation cost. Choose the RCBS Trickler 2 if manual workflow and modest cost are the priorities. Choose the RCBS Matchmaster if automated precision dispensing is the goal and the price is acceptable.

Troubleshooting
Trickler drops multiple kernels per turn instead of individual kernels. The most common cause is overfilling – too much powder in the tube creates excess head pressure on the auger. Empty the tube to half capacity and retest. If the problem persists, the auger channel may be worn or powder residue has packed into the auger threads. Disassemble the tube from the base, clean the auger threads with a small brush, and reassemble. If the auger is plastic and visibly worn at the thread crests, the unit needs replacement.
Powder bridges in the tube and stops flowing. Bridging occurs with coarse extruded powders – Hodgdon H1000, Vihtavuori N570, Alliant Reloder 50 – when the tube is filled too high or the powder has clumped from humidity. Tap the tube lightly against the bench to dislodge the bridge. For humidity-caused clumping, dry the powder before use. Keep the tube at half capacity with problematic powders.
Output tube slips from the set height during use. The height collar locking ring has loosened or the friction fit has worn. Tighten the locking ring firmly. If the collar continues to slip, a small wrap of PTFE tape around the tube at the collar contact point adds friction to restore the hold.
Scale reading fluctuates while trickling, making it hard to determine when the target weight is reached. This is normal with fast-response digital scales. Turn the trickler knob, then pause for two full seconds before reading the scale. Vibration from knob rotation transmits through the bench surface to the scale and temporarily destabilizes the reading. An anti-vibration mat under the scale reduces this effect, and positioning the trickler on a separate surface from the scale eliminates it.
Powder contamination between sessions – residue from previous powder in the tube affects new charge. Empty and brush the tube thoroughly between different powder types. Even a few kernels of a faster powder mixing into a slower one changes the effective burn rate in a way that pressure testing will not catch. If you load multiple powders regularly, label the trickler tube contents or use a dedicated trickler per powder type.
Frequently Asked Questions
Does the RCBS Powder Trickler 2 work with all powder types? Ball and small flake powders flow through the auger most smoothly – Winchester 231, Hodgdon Titegroup, Hodgdon Varget, IMR 4064, Hodgdon H4350 are all well-suited to this trickler. Short to medium extruded powders work with attention to fill level. Very long-grain stick powders like Hodgdon H1000 and Hodgdon Retumbo can bridge in the tube at higher fill levels – keep these powders at half tube capacity and expect occasional manual dislodging.
Can I use the RCBS Powder Trickler 2 without a powder measure – just filling the scale pan entirely from the trickler? Technically yes, but it is impractical for anything over a few grains. Trickling a full 40-grain charge of Alliant Reloder 26 from scratch would take several minutes per round. The correct workflow is: powder measure throws a charge 0.3-0.5 grains below target weight, trickler brings it to exact weight. The trickler handles the final increment, not the entire charge.
What scale should I pair with the RCBS Powder Trickler 2? Any quality scale works. Within the RCBS line, the RCBS M500 Balance Beam Scale and RCBS Rangemaster 2000 Digital Scale are natural pairings. Outside RCBS, the Lyman Accu-Touch 2000, Lyman Pocket Touch 1500, and Frankford Arsenal Platinum Series Precision Scale all pair well. For the trickler-and-scale workflow, a scale that reads to 0.1 grains is the minimum useful resolution; 0.02-grain resolution scales are better.
Is the RCBS Powder Trickler 2 different from the original RCBS Powder Trickler? The “2” designation indicates an updated version with design improvements over the original, primarily the adjustable output tube height and refinements to the auger mechanism. If you encounter old stock of the original at a lower price, the main practical difference is the fixed tube height – verify the tube height is compatible with your scale pan before purchasing the original version.
Should I consider an automated dispenser instead of a manual trickler? If you load more than 100-150 precision rifle rounds per month consistently, the RCBS ChargeMaster Supreme or Frankford Arsenal Intellidropper 2.0 is worth evaluating. The time cost of manual trickling at that volume is real. Below that threshold, the manual trickler workflow is practical and the $350-400 price difference buys a lot of other reloading components.
How long does the RCBS Powder Trickler 2 last under normal use? The metal auger is the long-life component. Under normal precision rifle loading use – a few hundred rounds per month – the auger should last indefinitely without wear-related performance degradation. The plastic body and tube are the wear items; cracking from dropping or overtightening the tube base is the most common failure mode. RCBS replacement parts for their trickler line have historically been available through their customer service channel.
Conclusion
The RCBS Powder Trickler 2 is a straightforward, durable manual trickler that does its job without complication. The metal auger outlasts plastic alternatives, the adjustable output tube accommodates different scale configurations, and the stable base keeps the unit in position during single-handed knob operation. At $25-35, it represents solid value for the precision rifle handloader who wants controlled, kernel-by-kernel charge weight management without committing to an automated dispenser.
The honest limitation is equally simple: trickling manually is slow. For a reloader who loads 200+ precision rifle rounds per session on a regular schedule, the time investment in per-round trickling becomes significant, and the case for an automated system like the RCBS ChargeMaster Supreme or Frankford Arsenal Intellidropper 2.0 grows stronger with every session. For the moderate-volume precision loader – 50 to 100 rounds of 6.5 Creedmoor, 308 Winchester, or 6mm Dasher per month – the trickler-and-scale workflow is entirely practical, and the RCBS Powder Trickler 2 handles it reliably.
Choose the RCBS Powder Trickler 2 if you load moderate volumes of precision rifle ammunition, already own a quality powder scale, and want manual trickling capability without the cost of an automated dispenser – particularly if you are already in the RCBS equipment ecosystem.
Choose the Frankford Arsenal Powder Trickler instead if it is available at a lower price and you do not have a strong brand preference – both tools perform the same function at similar price points.
Choose the Lyman Brass Smith Powder Trickler instead if you run Lyman Brass Smith case prep tools and want matched components that coordinate with the Brass Smith powder measure and funnel system.
Choose the RCBS ChargeMaster Supreme instead if you load high volumes of precision rifle ammunition regularly and the time cost of manual trickling per round is a meaningful constraint on your loading sessions.
