​Before choosing a case trimmer, it would be prudent for you to get the answers to the questions below. If only you can get the answers for each question, rest assured that you will end up with the better case trimmer that the market can offer for your specific needs. The questions are:

  1. How accurate would the case trimmer trim each of my bullet’s cases to their pre-set lengths​
  2. What is the speed or rather the cutting aggression of the trimmer?
  3. What additional functions would the case trimmer offer me?
  4. How square would the cut be made in reference to the case mouth and with respect to the case’s axis
  5. Is the case loading and offloading process easy?
  6. How much clean would the cut be when this case trimmer is used?
  7. What are the caliber pilots offered by the trimmer manufacturer and what are the acceptable cartridges (case head sizes)?
  8. Is this the good case trimmer for me at its range?

​Types of Trimmers

There are several case trimmer types available for you in the market. These include:

  • The Default: Lather-Type - This is the most common type carrying the likes of RCBS and Lyman among others
  • The fixed-adjustment type: It is the most simple as well as the lowest in cost
  • On-Press Trimming: A raw speed trimmer type
  • Shoulder-Indexing: For high-volume precision
  • Low-Volume precision type

The Default: Lathe-type Systems

The systems have been designed to clamp the bullet in some type of holder before trimming it using a cutter that would be extending from the trims opposite side. It comes with the possibility of making from crude to fine adjustments, as well as from slow to fast. This type has some of the best case trimmers just by the simple fact that they are capable of trimming literally any type and size of caliber there is in the market.

The Fixed-Adjustment: Simplicity and Low Cost

Each of these units have been designed for a single caliber size hence would only be a great choice if you are sure you will never want to change a gun and caliber. Its greatest advantages are its low price together with its simple design thus making it easy to load, trim and unload.

On-Press Trimmer: Raw Speed

This is an unbeatable type as far as raw speed is concerned. Unlike other trimmers that will take a few seconds to trim, chamfer and deburr the bullets, the on-press types take no time at all. Its trimming die also works as the sizing die hence upon sizing, you will also have trimmed. Killing two birds at ago!

Low-Volume Precision

Maybe the term low volume has been overstated since the system can be as fast as or even faster than some of the Lathe-types. The system is slow to set up thus a great choice for someone who infrequently changes their calibers. This type of case trimmer comes with a convenient clamp/stand mechanism for ease of use. Each caliber is reset using a new case holder and deburring tools aren’t included in the design. It is not the best choice of a case trimmer.

Shoulder-Indexing: High-Volume Precision

This is a type that would be used to trim large volumes of bullets per unit time. It is the good case trimmer for those who don’t mind some case-length variance. Insertion of cases is easy, chip management great and adjustment quite easy in deed.

​As you go shopping for a case trimmer, there are a number of factors worth great consideration. Such include the numbers of cases to be regularly trimmed and your budget among other factors that we are going to look it below.

​Factors of Consideration When Searching for the Best Case Trimmer

Amongst the very first things of consideration when shopping for the perfect case trimmer is the simplicity of design & construction and its ease to use. Look for a case trimmer that will work maybe by just chucking up its case on a drill or so, followed by simply running the trimmer.

1. Chamfering and Deburring

This is the process followed to smooth a case after the trimming has been done. After you trim your case, sharp edges around its mouth are always noticeable. With the use of Deburring tools, you can be able to cut such edges thus smoothing the case. Though Deburring tools can always be separately bought, it would be great if you consider a case trimmer that has this feature in its design or package.

​2. Shell Holders

Just as the name suggests, shell holders are used to hold the shell as the trimming & reloading process continues. Its purpose is to hold the case securely to the press. Since every type of caliber needs a different shell holder size, a wide range of holder sizes are available in the market. It is worth noting that there are some cheaper case trimmers that don’t need the shell holders for them to work. However, the good case trimmer for you would be the one that comes with shell holders having a high degree of adjustability.

​3. Tumblers and Polishers

Though not very necessary, some gun owners would really want their cartridge to have a shiny and good looking bullet thus the use of tumblers & polishers is introduced after trimming. Besides polishing the bullets, the tumblers and polishers can also be used in polishing the rifle thus lengthening its life. Some of the good case trimmers will come with this feature as an addition in the package.

As usual, after passing through the test of quality, what is good for me may not necessarily be good for you. As a result, you need to know what exactly you really want to do with a best case trimmer. Do you want high volume blasting ammo or the low-volume hunting ammo is the one you want to trim? Are you interested in high volume or low volume precision? And of course, what’s your budget?

What matters the most in trimming is the length consistency as well as the square case mouth. The case length should certainly be kept shorter than its maximum lest the case mouth jams against the gun chamber thus increasing the pressures of the bullet. As a result, the length consistency together with square mouths increases the accuracy of the shots. A good case trimmer is that which will help you to achieve these.
