What is a Case Trimmer?

The simplest and the best power case trimmer have the same purpose, trim cases so you can reuse them. Reusing cases saves you money as it allows you to reuse bullets that you’ve fired.

As a shooter you can just pick up the rounds you’ve fired and using a case trimmer, trim the round so you can use it again. While this is the basic definition of a case trimmer, the operation and features vary.

If you have never used a case trimmer before, it’s a good idea to learn the different types of case trimmers.

Types of Case Trimmers

The following are the most common case trimmers you’ll find.

  • Lathe Systems: the rim is clamped on a holder and on the other side is the trimmer cutter. These are adjustable and allow you to debur, trim and chamfer at the same time.
  • High Volume Precision: these shoulder indexing trim systems work in a similar manner: put your brass in the trimmer and the device trims it like a pencil sharpener. These trimmers are easy to work with.
  • Low Volume Precision: these are simple trimmers that suit those who don’t change calibers often. To replace calibers you just get a new case holder and reset the trimming.
  • On Press Trimming: these trimmers are fast and can debur, chamfer, trim and handle. The trim die and sizing die are the same so when you size it also trims.

 

How to Choose the Best Case Trimmer

If you’re looking for a case trimmer for 300 blackout there are several factors you’ll need to mull over.

Deburring and Chamfering

Chamfering and deburring refer to the procedures used to smooth a case after it has been trimmed. There will always be a few edges that need smoothing, but by deburring and chamfering you’ll be able to even these edges out.

Some case trimmers are bundled with these tools, which is great. If not it’s easy to find one of these as they’re essential.

Shell Holders

This is used to hold the shell while you reload and trim. What a shell holder does is keep the case press stable.

Case trimmer for 223 shell holders come in different sizes to accommodate the various calibers. That’s why it is crucial you buy a case trimmer which has the specs suitable for your caliber.

Polishers and Tumblers

Polishers and tumblers are used to polish bullets, plus you can use it to polish your guns and extend their lifespan. Many – not all – case trimmers have polishers and/or tumblers built in.

Case Trimmer Variant

The most common types have already been covered so there’s no need to go over them again. A few more points however:

  • High volume precision: for trimming lots of cases
  • Low volume precision: for occasional case changing
  • On press trimming: for fast results
  • Fixed adjustment: low cost and easy to use
  • Lathe type: the most widely used

No matter what you’re trimming, remember that a consistent length and square mouth are the most important. The case length has to be less than max otherwise the case could grip the bullet too hard.

The bottom line is a square mouth leads to more consistent releases, aids in accuracy and enhances bullet entry when seating. This in turn improves your marksmanship.

That’s a lot to factor in, but the trimmers reviewed here all adhere to the highest standards  and can deliver the results you’re looking for. These trimmers are also suitable for casual competition, plinking and hunting.

How to Use a Case Trimmer

The following is a general guide to using a case trimmer.  Please refer to your manual for more detailed instructions.

Mounting

Mount the case trimmer on a reloading bench at the location you want. Use C clamps or screws to secure it. Some of these case trimmers are bundled with a base plate or stand for greater stability.

There should be enough space for you to run the device comfortably.

  • Load a case in the case holder by holding and pushing the lever. Use your free hand to put the case base in, making sure that it’s flushed.
  • To run the trimmer, move the cutter shaft in the direction of the case holder until the cutter and pilot lock in the case’s mouth.
  • Hold the cutting knob, cranking the cutter in a clockwise manner. Keep turning the knob towards the case until finished. Forward pressure should be maintained throughout.
  • The trimming is done when the cutter guide and the adjustment bushings make contact. Move the cutter shaft towards the right.
  • Press the case holder lever and take the trimmed case out.
  • Debur and chamfer the case interior and exterior with chamfer / debur tool. Some case trimmers come with a 3 way tool that trims, chamfer and debur at the same time.
  • You can adjust the length using the adjustment bushing set on the cut shaft.
  • If the case trimmer isn’t running smoothly, you’ll need to do some maintenance work. Often you just need to remove brass debris and shavings and it should run smoothly.
  • It also helps if you lubricate the trimmer after every 300 cases. Any multi-purpose, lightweight grease will do.
  • Grease the cutter shaft, fine adjustment bushing face and case holder lever contact surface.
