RCBS MatchMaster 98820 Aluminum Powder Funnel Set

RCBS MATCHMASTER · 98820
A clean, reproducible transition from the measured powder charge into the case – with six precisely fitting interchangeable adapters in one set.
The RCBS MatchMaster Powder Funnel Kit 98820 is aimed at reloaders who switch between several common caliber or case neck groups and don’t want to improvise with a universal plastic funnel every time. The high-strength aluminum funnel has an anti-stick coating; RCBS includes six precision adapters for .22, 6 mm, 6.5 mm, 7 mm, .30, and .338 as well as a compact storage box.

Honest assessment
The 98820 is not a powder filler, scale, or electronic dispenser. It takes exactly the last mechanical step: guiding already correctly measured powder carefully into the case. Its added value is therefore not in higher charge accuracy itself, but in a high-quality funnel system that can be quickly adapted to different case neck groups.
Fits well: if you regularly use several of the six included sizes, value a sturdy aluminum funnel, and want to transfer stick, ball, or flake powder cleanly into the case.
Fits less well: if you only load a single caliber and a simple funnel already reliably covers your process – or if your required adapter size is not among the six supplied sizes.

Purchase check before ordering


Included adapters: .22, 6 mm, 6.5 mm, 7 mm, .30, and .338.

Not to be understood as a full range: The kit covers exactly these six sizes named by RCBS. Additional MatchMaster adapters are available separately.

Product purpose: powder transfer into the case. Weighing or dosing the charge is still done with a dedicated powder measuring or weighing system.

Powder types: RCBS explicitly describes the funnel for stick, ball, and flake powders.

Workbench workflow: Especially useful when loading multiple calibers at the same workstation and adapters should remain organized and quickly accessible.

What the design brings in practice
RCBS specifies the funnel as high-strength aluminum with a high-quality anti-stick surface. This design is intended to reduce sticking and support the flow of different powder types. The six adapters are intended as precisely fitting interchangeable adapters for the mentioned sizes. An independent expert test of the exact 98820 additionally describes the funnel as 6061-T6 aluminum with anodized surface. Since RCBS does not specify the exact alloy on its own 98820 product page, 6061-T6 is deliberately cited here as a specialist source reference and not as a manufacturer specification.
An independent expert test by RifleShooter describes the adapters as coarse-threaded with a grippy knurl and highlights the very fast flow even with long-grain stick powders. However, the same test also showed a practical limit: the upper funnel opening is comparatively compact, so hasty or inaccurate pouring can push individual grains over the edge. This is a good reason not to understand the manufacturer’s advertising “without spilling” as a physical guarantee.
Important for assessment: even a high-quality funnel does not replace clean loading organization. The correct powder amount is not determined by the funnel, and the anti-stick coating is no reason to neglect control over case fill level, powder type, and the rest of the loading process.

Compatibility and limits
The 98820 includes adapters for .22, 6 mm, 6.5 mm, 7 mm, .30, and .338. RCBS calls them precision-fit adapters for popular caliber groups. Therefore, the purchase decision should be based on the actually needed adapter and not on the assumption that the kit covers every cartridge.
case from .22 to .338 automatically covered.
A secure fit of the case in the loading block remains important. RifleShooter points out from practical use that too large holes in the loading block can cause the case to tilt when the comparatively massive aluminum funnel is placed on. This does not fundamentally prevent the function but makes clean pouring unnecessarily more difficult.
Those who need sizes outside this delivery scope should check the modular MatchMaster system before purchase. The separately offered RCBS MatchMaster Powder Funnel 98821 is described by the manufacturer with separately available MatchMaster adapters in the range of .17 to .50. This makes the single funnel more interesting if adapters are already available or if other sizes are to be specifically built.

User and instructor notes

Sort the six adapters by size before loading and consciously select the adapter intended for the respective case neck/caliber group. This reduces confusion when changing calibers.
RCBS explicitly designs the system for stick, ball, and flake powders. Especially when switching between different powder forms, it is worth visibly checking the free passage of the funnel before the next series.
A suitably dimensioned, stable loading block hole is sensible: The independent expert test describes that loosely fitting cases are more likely to tilt under the aluminum funnel. So check for a stable fit before pouring.
The more compact upper opening rewards a controlled, centered pouring process. Do not pour powder sideways or with unnecessary momentum into the funnel – it was precisely here that the expert tester occasionally observed grains jumping out.
The compact box is not just packaging: it is useful for storing the six adapters as a matching set and immediately recognizing missing parts when changing the workplace.
In training, a clear separation should be made between dosing/weighing and filling. The MatchMaster kit optimizes the filling step; it does not provide any statement about whether the powder charge itself was correctly measured.

98820 kit or 98821 single funnel?
Choose 98820: if you want a complete set with aluminum funnel, six frequently used adapter sizes, and storage box right away.
Check 98821: if you want to configure the MatchMaster funnel specifically with separately available adapters or need sizes outside the six kit adapters. RCBS lists separately available MatchMaster adapters for 98821 in the range of .17 to .50.

FAQ about the RCBS MatchMaster 98820
Which adapters are included in the set? .22, 6 mm, 6.5 mm, 7 mm, .30, and .338 – a total of six interchangeable adapters.
Dosie
rt or does the funnel weigh the powder? No. The 98820 is a powder funnel system for transferring an already correctly measured charge into the case.
For which powder types is the funnel intended? RCBS lists stick, ball, and flake powders.
Does the kit automatically cover all calibers from .22 to .338? No. It contains exactly the six specified adapter sizes. For sizes not included, suitable additional MatchMaster adapters must be checked.
What does the anti-stick coating do? According to the manufacturer, it is designed to reduce sticking and support the powder flow through the aluminum funnel. However, it does not replace monitoring the loading process and does not guarantee that no individual grains are spilled when pouring carelessly.
Do I need a special loading block? RCBS does not specify a proprietary loading block as mandatory. In practice, the respective case should sit as upright and stable as possible; a specialist test reports that loading block holes that are too large can make handling the heavier aluminum funnel more difficult.
When is the separate MatchMaster Funnel 98821 the better alternative? If you already have suitable adapters or want to configure your system specifically with other sizes. RCBS offers separately available MatchMaster adapters for the 98821 in the range of .17 to .50.
