At some point in their shooting career, nearly every gun owner arrives at the same conclusion: I should start reloading my own ammunition. It’ll save money.

That thought usually leads to a few late nights on YouTube, several deep dives into online forums, and a conversation with a friend who has a reloading bench that looks like a cross between a chemistry lab and a machine shop. Eventually, curiosity wins, equipment gets purchased, and the journey into reloading begins.

Most reloaders start with pistol cartridges—typically 9mm or something similar. It’s a logical place to begin. The cases are straight-walled, the process is relatively forgiving, and the workflow is simple. Clean the brass, deprime it, resize it, and you’re well on your way.

Before long, confidence sets in. Reloaders start to feel like they’ve got things figured out.

Then they move to rifle cartridges.

And that’s when they discover case trimming.

Now, trimming rifle brass isn’t actually worse than death—but after starting with pistol calibers, it can feel close. Rifle brass stretches during firing and resizing, and if it grows beyond the maximum case length specified for the cartridge, it must be trimmed back down to a safe dimension. It’s an important step for reliability, safety, and consistency, but it also happens to be one of the least exciting tasks in the entire reloading process.

For years, case trimming has been the chore that reloaders endure rather than enjoy.

Fortunately, RCBS decided to do something about it.

A Better Approach to an Old Problem

Recognizing how tedious traditional trimming methods can be, RCBS partnered with Henderson Precision to develop the RCBS MatchMaster Precision Case Trimmer. The goal was simple: create a trimmer that delivers outstanding accuracy while dramatically improving speed and ease of use.

If you’ve spent time with older trimmers, the difference is immediately obvious.

My first case trimmer was hand-powered, required multiple adjustments every time I switched calibers, and looked like it might have been designed sometime around the Lewis and Clark expedition. It worked, technically—but the process of trimming a few hundred rifle cases could turn an otherwise relaxing reloading session into an endurance event.

If the MatchMaster had been available when I started reloading rifle cartridges, I’m fairly certain I would look about ten years younger, and my kids would have grown up hearing significantly fewer four-letter words coming from the basement.

Feature-Rich by Design

The RCBS MatchMaster Precision Case Trimmer isn’t just a motorized version of older designs. It’s a purpose-built system built to streamline the entire trimming process.

At the center of the system is a high-speed custom motor that eliminates the need for hand cranking. Anyone who has trimmed hundreds of cases by hand knows exactly how welcome that upgrade is.

Even more impressive is the 3-way cutter. Rather than performing multiple steps separately, the cutter trims, chamfers, and deburrs the case mouth in a single operation. That means when the brass comes off the trimmer, it’s already properly finished and ready for the next stage of the reloading process.

The trimmer accommodates a wide range of cartridges, handling calibers from .22 up to .338 and case lengths from 1.36 inches to 2.85 inches. That range covers the overwhelming majority of rifle cartridges most reloaders are likely to encounter.

RCBS also integrated a brass shaving collection system, which is a small detail that quickly proves its value. Anyone who has ever vacuumed brass shavings out of carpet understands why this matters.

Additional features include a dedicated case catcher bin to keep trimmed brass separated from untrimmed cases, a rugged motor mount, and a heavy-duty base plate that can be easily secured to a workbench for stability while operating.

Taken together, these features make it clear that the MatchMaster was designed with real reloaders—and real reloading benches—in mind.

The Micrometer That Saves Time

Perhaps the most impressive feature of the MatchMaster system is its integrated micrometer adjustment.

With many traditional trimmers, dialing in the correct trim length involves a slow process of trimming a case, measuring it, making a small adjustment, trimming again, measuring again, and repeating the process until the correct length is achieved.

Then comes the real frustration: switching to a different caliber.

At that point, the entire adjustment process begins again. And if you later switch back to the original caliber, you’ll likely be repeating the same routine all over again.

The MatchMaster solves this problem elegantly. The precision micrometer adjustment allows the user to quickly dial in a trim length and record the setting for future use. When switching calibers, simply return the micrometer to the recorded setting and you’re ready to go.

For reloaders who process multiple rifle cartridges, this feature alone can save a significant amount of time.

In fact, it’s not uncommon for experienced reloaders to maintain entirely separate trimming setups for different calibers just to avoid constantly resetting their equipment. The MatchMaster essentially eliminates that need.

Pilots Included—Right Out of the Box

Case trimming requires a part called a pilot, which is a guide rod sized to match the diameter of the case mouth. The pilot assures that the case remains properly aligned with the cutter during trimming.

Some manufacturers include a single pilot and sell the rest separately.

RCBS decided to take a more user-friendly approach.

The MatchMaster includes seven pilots right out of the box, covering:

• .22 caliber
• .24 caliber
• .25 caliber
• .26 caliber
• .27 caliber
• .28 caliber
• .30 caliber

This selection covers the vast majority of popular rifle cartridges used by hunters, competitors, and recreational shooters alike.

For those working with larger cartridges such as .338 Lapua Magnum, additional pilots are readily available through Midsouth Shooters Supply.

A Collet System That Covers Nearly Everything

Another primary feature is the universal collet system.

For anyone new to case trimming, the collet is the part of the trimmer that holds the base of the brass case securely in place during trimming. A poorly designed collet system can slow down the entire process.

The MatchMaster includes Collet #1, which supports 41 different calibers with rim diameters of:

• .379 inches
• .473 inches
• .532 inches

In practical terms, this means the included collet works with a huge range of common cartridges right out of the box.  A full list of the 41 different calibers is on the RCBS website.

Additional collets—#2, #3, and #4—are available for cartridges outside that range, extending compatibility to everything from .30-30 Winchester to .338 Lapua Magnum.

The result is a trimming system that can easily grow with a reloader’s needs over time.

Final Thoughts

Most reloading equipment evolves slowly. Manufacturers make small adjustments, tweak designs, and release products that differ only slightly from what came before.

The RCBS MatchMaster Precision Case Trimmer feels different.

By partnering with Henderson Precision, RCBS didn’t just update the traditional case trimmer—they built a system that actually improves one of the most tedious parts of rifle reloading.

It’s fast, precise, and intentionally designed, with features that address the frustrations reloaders have dealt with for decades.

Somewhere in the RCBS office, I imagine Joel Hodgdon confidently channeling Bret “The Hitman” Hart when he even thinks about this case trimmer and saying:

“I’m RCBS is the best there is, the best there was, and the best there ever will be.”

When it comes to case trimming, that might not be far from the truth.

Whether you’re new to rifle reloading, expanding into additional calibers, or simply looking to upgrade your bench, the MatchMaster Precision Case Trimmer is one piece of equipment that can greatly improve your workflow—and make case prep far simpler.

And if you see one available in stock, it might be wise to grab it.

Because nothing makes a reloader question their life decisions quite like seeing the words:

“Currently Out of Stock.”
