Getting your case length right isn’t just a suggestion; it’s a cornerstone of safe, consistent reloading. A case that’s too long can prevent chambering or create dangerous pressure spikes, while one that’s too short can lead to poor ignition and accuracy issues. This fundamental measurement dictates whether you need to trim, and by how much, making a reliable gauge or trimmer indispensable. Two tools often find themselves on a reloader’s shortlist: the comprehensive Frankford Arsenal Platinum Series Case Trim and Prep System and the straightforward Ludex Ammo Case Length Gauge. They serve different primary functions, but both aim to solve the same core problemensuring your brass is within spec.
between a full case prep station and a dedicated measuring tool depends entirely on your workflow and needs. To be completely honest, a beginner might prioritize simple verification, while a high-volume shooter likely wants an all-in-one processing solution. We’re going to break down each product’s actual capabilities, compare them head-to-head, and help you decide which tool earns a permanent spot on your reloading bench setup.
Frankford Arsenal Case Prep System: The All-in-One Workhorse
The Frankford Arsenal Platinum isn’t just a gauge; it’s a complete processing center. Its designed for the reloader who wants to take resized brass and perform multiple trimming and preparation steps in one powered unit. Its core function is as a precise ammo case trimmer, but it bundles several other essential tools into a single system.
Features & Core Functionality
This system is built around a durable motor and drivetrain, promising longevity through thousands of rounds. The key to its reloading precision is how it handles cases: the trimmer indexes on the case shoulder, not the mouth, which promotes consistent length and superior concentricity. This method is generally considered more accurate than trimmers that reference the case mouth, which can be uneven.
- Versatile Collet System: It works with a wide range of shouldered rifle cases, from .17 Remington up to .460 Weatherby. The adjustable collet and six included shoulder bushings cover a lot of ground.
- Integrated Toolset: Beyond trimming, it comes with tools for inside chamfering, deburring, and cleaning both large and small primer pockets. This turns it into a true case preparation station.
- Built for Durability: It uses hardened High-Speed Steel (HSS) cutters designed to stay sharp through extensive use. The unit also has a built-in storage box to keep all components organized.
Honestly speaking, its value lies in consolidation. Instead of separate hand tools or multiple single-purpose devices cluttering your bench, this system aims to streamline the entire post-resizing preparation process. For someone processing hundreds of rifle cases, the speed and integrated workflow are major advantages. You can read more about optimizing your reloading workflow on our site.
Ludex Ammo Case Length Gauge: The Specialized Verifier
The Ludex gauge takes a completely different, minimalist approach. It doesn’t trim, chamfer, or deburr. Its sole purpose is to answer one critical question: “Is this case too long?” It’s a dedicated reloading case gauge for measurement only, functioning as a rapid go/no-go gauge for case length.
Features & Core Functionality
Constructed from a hard alloy, the Ludex gauge is a simple, durable block. It features laser-etched markings for over 70 popular cartridges, designed not to fade. You drop a fired or resized case into the appropriate chamber, and if the case mouth sits above the gauge’s surface, it signals that trimming is required.
- Pure Measurement: It provides an easy and accurate method for case length measurement, suitable for both fired and resized brass. It quickly sorts out over-length cases.
- Broad Cartridge Compatibility: Covering 70 cartridges makes it highly versatile for reloaders who work with multiple calibers without needing to change bushings or collets.
- Simplicity and Speed: The process is instantdrop in, check, move on. It requires no setup, calibration, or power, making it perfect for a final check before loading.
From my honest perspective, the Ludex excels in its simplicity. Its the tool you use to verify the output of your trimmer or to quickly check a batch of range brass before deciding what needs processing. Its a classic example of a tool that does one job very well. For insights on other precision tools, check out our picatinny accessory guides.

Diving Deeper into the User Experience
For the Volume Processor: If you’re decapping, resizing, and then prepping 500 .223 cases, the Frankford Arsenal system is a time-saver. You trim, chamfer, deburr, and clean primer pockets with minimal tool switching. The motor does the hard work. Speaking honestly, the initial setup for a new caliber takes a few minutes, but once it’s dialed in, it’s a production line.
For the Meticulous Checker or Beginner: The Ludex gauge is about confidence. After trimming on any device (even the Frankford), you can quickly verify every case meets SAAMI spec. It’s also the perfect tool for the new reloader wondering how to measure case length for reloading without complexity. My honest assessment is that its a fantastic teaching tool and a universal quality control checkpoint.
A point often missed in reloading tool accuracy discussions is calibration. The Frankford Arsenal requires you to set the trim length correctly using the provided wrench and a reference casea simple but crucial user calibration. The Ludex gauge is pre-calibrated by its machining; your job is simply to read it correctly. Both methods are valid, but they place the responsibility for initial setup in different places.
