Redding Model 2400 Case Trimming Lathe

The Redding Model 2400 case trimming lathe is built for reloaders who demand precise, repeatable case length control across a wide range of calibers—from modern short-action rounds to longer classic and magnum cartridges. This bench-mounted trimmer combines Redding's proven trimming design with a micrometer head for fine adjustment and a push-button chuck lock that speeds up case handling without sacrificing alignment. Whether you're preparing cases for precision rifle loads, hunting ammunition, or specialty rounds, the 2400 delivers the accuracy that tight case-length tolerances demand.

The extended cast iron frame is the key upgrade here: it handles cases up to 3.25 inches in length, covering everything from standard rifle cartridges to long-action and classic big-bore rounds. The micrometer adjustment works in increments as fine as .001 inch, so you can dial in exact case lengths and repeat them shot after shot. The push-button chuck lock makes it simple to seat and remove cases while keeping perfect pilot alignment—no fiddling, no guesswork. Setup and operation are straightforward, making this trimmer accessible to newer reloaders while remaining efficient for high-volume work.

Redding supplies a comprehensive starter kit of pilots and accessories: six case pilots covering .22 through .30 caliber, two neck cleaning brushes for .22–.30 cal, and both large and small primer pocket cleaners. That means you can trim multiple calibers right out of the box without hunting down extras.

Frequently Asked Questions

What calibers can the Redding Model 2400 trim?

The 2400 handles any caliber with cases up to 3.25 inches long. That covers standard rifle cartridges, long-action rounds, magnum cartridges, and classic big-bore loads. The six included pilots support .22, 6mm, .25, .270, 7mm, and .30 caliber. Additional pilots are available separately if you reload other sizes.

How precise is the micrometer adjustment?

The micrometer head adjusts in .001-inch increments, allowing you to set exact case lengths and repeat them consistently. This precision is essential for competitive, long-range, and precision hunting loads where case length uniformity directly affects cartridge concentricity and velocity.

What's included in the box?

The Model 2400 ships with six case pilots, two neck cleaning brushes for .22–.30 caliber, a large primer pocket cleaner, and a small primer pocket cleaner. Everything needed to trim and prep cases across most common rifle calibers.

Is the push-button chuck lock just a convenience feature?

It's more than that. The push-button lock simplifies case handling and ensures perfect alignment between the collet and pilot every time you load or unload a case. Consistent alignment means consistent trim lengths and minimal setup time between batches.
