Two manual case trimmers consistently dominate the conversation among reloaders: the Hornady Cam-Lock 050140 and the RCBS Trim Pro-2. Both promise to deliver the precise, consistent case length that’s non-negotiable for accuracy, whether you’re prepping for a benchrest match or a high-volume session. But their approaches to achieving that goal are fundamentally different, leading to a real fork in the road for your brass prep station.
This isn’t just about trimming a few thousandths off a case mouth. It’s about workflow, feel, and long-term satisfaction with your reloading tools. The choice you make will impact every batch of ammunition you produce. Let’s break down how these two titans of cartridge trimming stack up.
Head-to-Head: Hornady Cam-Lock vs. RCBS Trim Pro-2
At their core, both tools accomplish the same task. The devil, as always, is in the details. The Hornady leverages a unique cam-action locking mechanism for speed, while the RCBS employs a more traditional threaded design. This single difference cascades into every aspect of their operation, from setup to daily use.

Precision & Consistency: Which Case Trimmer is More Accurate?
For precision shooting, repeatability is king. Both manufacturers emphasize accuracy, but they ensure it differently. The Hornady’s system holds the case square with the cutter via its locking lever and measures all trim lengths from the head of the cartridge, a critical point for consistency. Its micrometer adjustment allows for incredibly fine, repeatable adjustments without moving the casea huge benefit when dialing in the perfect length for your chamber.
The RCBS is built to achieve “the highest level of accuracy” with adjustable settings for reliable performance. Honestly speaking, the threaded locking system on the Trim Pro-2 can provide a very solid, vibration-free hold, which is essential for a clean cut. The question of which case trimmer is more accurate Hornady or RCBS often comes down to the operator’s technique and how well each tool’s method meshes with their process. Both are fully capable of sub-thousandth consistency in capable hands.
Setup, Operation & Ease of Use Compared
This is where these trimmers truly diverge. The Hornady Cam-Lock is built for speed. The lever-action lock is fastyou turn it to secure the case and feed it onto the cutter pilot. There’s no threading a collar on and off. This can shave seconds off each piece of brass, which adds up dramatically. It uses a universal shell holder system, meaning you likely already have compatible holders if you use a Hornady reloading press.
However, some users report Hornady Cam-Lock 050140 setup problems related to initial alignment or mounting. Ensuring the base is perfectly secure is paramount. The RCBS Trim Pro-2 has a more straightforward, traditional operation. You insert the case, thread the locking collar to secure it, and trim. It’s a proven, simple motion. For high-volume trimming, the threading action can feel slower, but it’s a rhythm many reloaders find meditative and secure.
My honest take is that the Hornady feels more specialized for speed, while the RCBS feels more universally accessible. Your preference for a quick lever versus a threaded collar will be a major deciding factor.
Specific Caliber Performance & Considerations
While both handle a wide range, performance with specific calibers can vary. For example, in an RCBS Trim Pro-2 vs Hornady for 223 brass scenario, the Hornady’s cam-lock might offer a speed advantage for processing hundreds of small rifle cases. The included pilots cover most common needs, but always verify your specific caliber, like .308 Winchester or 6.5 Creedmoor, is covered by the standard set or requires an additional purchase.
Durability, Build Quality & Long-Term Value
These are tools meant to last decades. The Hornady boasts a large diameter, replaceable cutting head made of ultra-hard tool steel, designed to trim up to .50 caliber. The entire unit feels robust, and the cam-lock mechanism is built for repeated, high-force engagement. The RCBS is described as made from high-quality, durable materials built to last, a hallmark of the brand.
Long-term maintenance is a consideration. The Hornady’s cutting head is replaceable, a nice feature. Both trimmers will benefit from occasional cleaning of brass shavings and light lubrication on moving parts. Speaking honestly, the noise and vibration are generally low on manual trimmers, but a secure mount minimizes any chatter. When considering is the Hornady trimmer worth the extra money, you’re paying for the patented cam-action mechanism and the potential speed gain. The RCBS often presents a compelling value in its kit form.
