RCBS Matchmaster Powder Funnel .17

• Caliber-specific fit: The .17 adapter is sized for very small case mouths, helping powder enter cleanly instead of spilling around the neck during careful handloading work.
• Built for the MatchMaster system: This adapter works with the RCBS MatchMaster Powder Funnel, giving reloaders a modular setup that can be matched to the cartridge family they load most often.
• Cleaner powder transfer: A precise fit at the case mouth helps maintain a more centered powder stream, which is especially useful when working with small-caliber cases where minor spills are more noticeable.
• Useful for precision reloading: For .17 caliber cartridges, the dedicated adapter supports a more controlled charging process, reducing interruptions and helping keep the loading bench tidy.
• Compact bench accessory: As a small, purpose-built reloading accessory, it adds caliber-specific functionality without taking up space or complicating an existing powder charging setup.

About the MatchMaster Series

The RCBS MatchMaster series sits at the more precision-focused end of the company’s reloading lineup. It is aimed at reloaders who want greater consistency, cleaner workflow, and better control over each step of the loading process, whether they are assembling ammunition for competition, varmint shooting, or careful load development. Across the series, the emphasis is on tools that reduce small errors and make repeatable results easier to achieve.

Within that family, MatchMaster powder-handling tools are designed to improve how powder moves from measure to case. The system uses a modular funnel-and-adapter layout so the setup can be matched to cartridge size rather than relying on a one-size-fits-all opening. That approach is especially useful when loading smaller calibers, where clean alignment matters more and stray kernels are more likely to end up on the bench instead of in the case. The series reflects RCBS’s practical design philosophy: durable materials, straightforward bench use, and purpose-built accessories that support a more controlled reloading routine.

About the RCBS Matchmaster Powder Funnel .17

The RCBS Matchmaster Powder Funnel .17 is a caliber-specific adapter made for reloaders working with .17 caliber cartridges. Small case mouths leave little room for error during powder charging, so a dedicated adapter like this helps guide powder more directly into the case instead of letting it scatter around the neck or loading block. In practice, that means a cleaner bench, less wasted powder, and fewer interruptions during a loading session.

Used with the RCBS MatchMaster Powder Funnel, this adapter becomes part of a system built around fit and control rather than compromise. The .17 size is particularly useful for handloaders assembling ammunition for small-bore centerfire cartridges, where precise case handling and tidy powder transfer are important to maintaining an efficient workflow. Because the adapter is matched to a very narrow bullet diameter, it supports more consistent alignment at the case mouth than a broader universal funnel opening would.

As a reloading accessory, the value of this model is its specialization. The 4.40 mm / .172 caliber size is intended for a very specific application, and that is exactly why it matters on the bench. Instead of adapting a general-purpose tool to a small cartridge, this RCBS accessory gives the loader a component tailored to the job, making powder charging more orderly and better suited to fine, detail-oriented handloading work.

About RCBS

RCBS was founded in 1943 by Fred T. Huntington in Oroville, California. The company name came from Rock Chuck Bullet Swage, the original bullet-swaging die that started the business. Over the decades, RCBS became closely associated with ammunition handloading, building its reputation on practical tools for rifle and pistol cartridge reloading.

Today, RCBS specializes in reloading equipment such as presses, dies, shell holders, powder measures, and priming tools. Its catalog covers single-stage, turret, and progressive press systems, reflecting a broad focus on both entry-level and experienced handloaders. RCBS became a brand of Hodgdon Powder Company in 2024, while continuing its long-standing connection to reloading tools and bench equipment in the United States.
