Case Trimmer Buyer's Guide : How to Make the Perfect Choice?

Before talking about specific products, I wanted to first address some important factors that will help you to determine what the best trimmer to purchase is. Here are some criteria to consider.

  1. Cutter Material

    This should be the primary factor in determining which case trimmer you desire. Most will have a basic steel cutter, which will do the job effectively. However, there are some brass options out there which aren’t nearly as hard. If you are intending to do high-volume reloading, you may want to look at something harder, maybe even carbide.

  2. Manual vs. Electric

    It is a little more difficult to use a trimmer than you may have thought, especially if it has a small crank that you have to turn repetitively to get it to work properly. If you are a person who is doing a number of rounds consistently, you really may want to look at choosing an electric option to save yourself from becoming fatigued.

  3. Durability

    The quality of the product is important as well. Consider the fact that this is a tool that is designed to perform a specific task and to do it with great efficiency. You want something that is going to have a durable construction and be able to handle the workload.

  4. Accessories

    Accessories are always a nice feature to have with any product you purchase, and that is true of the case trimmer is well. Some come with a replaceable cutter, dies, or other tools. If you are a person who is looking to trim many different caliber rounds, finding one with accessories that can handle a diverse load is really in your interest.

  5. Price

    If we are realistic, you have to admit the price is always a concern. You want to get something that fits within your budget, but something that also works effectively. The truth is that if you can spend $25 more for a higher grade quality trimmer you should be willing to do so.

Most Frequently Asked Questions

Before ending this review, I wanted to address some of the more common types of questions that I am asked by people. I thought this would help you to make more informed decisions and have a better understanding related to trimmers.

  1. Why you need a case trimmer?

    The purpose of the case trimmer allows you to trim your cases so that you are able to reuse them. This allows you to save money and create rounds that are generally more accurate than the ones you would purchase at the store.

  2. Do I need to trim every case?

    The answer to this is no. It should be done on a regular basis, but that can be as regular as every two or three times that you reload. That should be sufficient enough.

  3. How to Use a Case Trimmer?

    Because some trimmers are different than others, here are some general guidelines on what you should do.

    Begin by mounting the case trimmer in place. Some have options that allow you to screw it directly into your workbench, or you may have to use a vice, reloading press, or clamps to accomplish the task. When doing this, ensure that there is enough space to be able to work and that the bench is stable in its location.

    • Load the case into the case holder and make sure that it is flushed.
    • Move the cutter shaft in the direction of the case holder and tell the cutter is located against the mouth of the case.
    • While holding the cutting knob, turn the cutter in a clockwise manner until the case is finished. The trimming has been accomplished when the guide and the bushings come in contact.
    • Remove the trim case and then finish off the case using the chamfer or debur tool.

    As a quick note, make sure that you lubricate the trimmer on a regular basis, at least after using it 300 times. Also check your fine adjustments on a regular basis.

  4. How do I set up the trimmer the first time I use it?

    This is a little more complicated answer than you would think. Because every trimmer is a little different, the best thing that you should do is to review the guide that came with your case trimming product. This should give you instructions on exactly what you need to do, including how to mount the product properly.

  5. What should I do if the case is too big for the case holder?

    If this is the case, you have one of two options. If the trimmer allows you to use larger size case holders, then you may have to purchase a different sized case holder to be able to handle the trimming process. You may also have to consider the fact that your trimmer may not work for that size case. This will likely require you to purchase a different product to be able to complete your trimming.

  6. How to keep out my case trimmer from rusting?

    Rust is created when humidity or water come in contact with metal. The best thing that you can do to prevent this from happening is to properly store your device in a location that is low in humidity. If you have a gun cabinet, this would be an ideal place.

    However, many people install their case trimmer to their workbench, meaning that they can’t simply take it out and put it away. In this case, you need to do two things. First, there are gels and oils that you can purchase that you would place a very light film over the entire product. This acts as a barrier to keep moisture from being able to get on the trimmer. Also, regularly wipe down the trimmer so that humidity does not have a chance to build up. This should be done daily.
