Frankford Arsenal Platinum Series Case Trim and Prep System

In this review the Frankford Arsenal Platinum Series Case Trim and Prep System is evaluated for reloaders who want faster, more consistent brass prep. The bottom line: it is a shop-grade benchtop trimmer that speeds case length control and adds useful finishing tools, with the biggest reason to buy being the trimmer's shoulder-indexing and adjustable collet system that handles a very wide range of shouldered cartridges cleanly and quickly.

Key Features

• Indexed Trimming: The trimmer indexes cases on the shoulder for repeatable, fast length control so batches of brass come out uniform without constant measuring.
• Adjustable Collet System: The included collets and shoulder bushings let the unit center everything from.17 Remington to.460 Weatherby without jury-rigging, saving setup time for multiple calibers.
• Hardened HSS Cutters: High speed steel cutters retain an edge for thousands of rounds, so trimming remains quick and requires minimal frequent replacement.
• Complete Prep Tools: Inside chamfer, deburr, and large and small primer pocket scrapers are included so users can perform finishing operations at the same station.
• Built-in Storage: An integrated storage box keeps extra tools and bushings organized and ready, reducing lost bits and bench clutter.

Who It's For

The Platinum Series is aimed at hobbyist and small-scale competitive reloaders who process dozens to hundreds of cases and want consistent, shoulder-indexed trimming with the convenience of dedicated chamfer and primer-pocket tools. It particularly fits users who reload multiple calibers and need a single machine to cover a wide size range.

Those who should look elsewhere include absolute casual reloaders who only trim a few cases a year and can get by with a manual hand trimmer, or shops that require fully automated, high-throughput production systems beyond a benchtop motorized trimmer.

Pros & Cons

Pros

• Durable HSS cutters keep sharp for thousands of rounds, so running costs are low.

• Built-in storage and included chamfer, deburr, and primer pocket tools make it a true all-in-one prep station.
• Indexes on the shoulder for speed and precision, cutting overall prep time significantly.

Cons

• As a benchtop trimmer it is not designed for fully automated, high-volume production lines.
• Users trimming only occasional cases may find the initial investment higher than a simple manual trimmer.
