Buyer’s Guide

What is a Case Trimmer?

A case trimmer is a tool that helps you trim brass cases down to size. This is important because brass cases expand when fired and need to be trimmed down periodically in order to ensure proper fit and function in your firearm. There are many different types and brands of case trimmers on the market, so it’s important to choose one that will work well for you.[1]

What do I need to consider before buying a case trimmer?

There are a few things you’ll want to keep in mind when choosing a brass case trimmer:

Trimer versatility

Think about if the cartridges you shot are all of the same type. If so, you might want to think about finding the best case trimmer that can resize various shell kinds.

Trimer versatility

By using a universal case trimmer, you can save spending money on case trimmers for particular firearms and trim shells from a variety of weapons.

Power source

Most trimmers are either hand-powered or electric.

Hand-powered trimmers are typically less expensive, but they can be slower and more difficult to use.
Electric trimmers are generally faster and easier to use, but they will require an electrical outlet.

Lifetime of Blade

One of the most important things to consider when choosing a brass case trimmer is the lifetime of its blade. You’ll want to make sure that you choose a trimmer with a blade that will last for many reloads. Otherwise, you’ll find yourself having to replace the blade frequently, which can be costly.

Caliber Compatibility

You’ll also want to make sure that the trimmer you choose is compatible with the caliber of brass you’ll be reloading. Most trimmers will indicate what calibers they’re compatible with on their product page.

Material of the Cutter

The cutter is the part of the trimmer that actually does the cutting. It’s important to choose a cutter made from high-quality materials, such as hardened steel, so that it will stay sharp and last for many reloads.

Ease of Use

Another important consideration is how easy the trimmer is to use. You’ll want to make sure that it’s easy to set up and use, especially if you’re new to reloading. Some trimmers can be more difficult to use than others, so it’s important to read reviews before making your purchase.

Overall Quality

Another important factor to consider is the overall quality of the case trimmer. This is important because you want a product that is going to last. Look for case trimmers that are made from high-quality materials such as stainless steel. This will ensure that your case trimmer will last for many years to come.

Portability

Portability is another big factor to consider.

If you plan on doing a lot of reloading on the go, then you’ll want to make sure that the brass case trimmer you choose is portable enough to take with you.
Some brass case trimmers are small enough to fit in your pocket, while others are larger and require a bit more space.

Budget

Finally, you need to consider your budget. Case trimmers can range in price from around $30 to over $100. It’s important to find a case trimmer that fits your budget. However, don’t sacrifice quality for price. It’s better to spend a little more and get a high-quality product than to save money and end up with an inferior product.

Time required for each trimming

This element is not very significant if you are a casual shooter with a few brass cases that need trimming. But, for those who have to trim hundreds or even thousands of brass cases, the time required for each trimming is an important consideration.

The hand crank that comes with some manual trimmers can be replaced with a power adapter and drill press. Or, although it will cost more, you can start out with a motorized trimmer.

What features should I look for in a case trimmer?

There are a few features that you should look for in a brass case trimmer:

Accuracy of the Trim

This is important because you don’t want your brass cases to be too short or too long. The best way to ensure accuracy is to get a case trimmer that has a micrometer adjustment. This way, you can precisely adjust the length of the trim according to your needs.

High speed

The best trimmers have rapid cutting rates. Your fired cartridges should be able to be resized in a short amount of time.

Easy to operate

You don’t want a trimmer that is difficult to operate. The best trimmers are those that are easy to use and require minimal setup. You can easily load and unload the cartridge.

Extra features

Some trimmers come with extra features that can be useful. For example, some trimmers have a case-feeder attachment that can save you time. Others have a power adapter so you can trim brass cases without having to use a separate power source.

The number of caliber pilots

The number of caliber pilots is important because it determines how many different types of brass cases the trimmer can trim. If you only plan on trimming one type of brass case, then a single-pilot trimmer will suffice.

The number of caliber pilots

However, if you want to be able to trim multiple types of brass cases, then you should get a trimmer that has multiple pilots.

Expected Results

If a case trimmer can generate the cartridge length you require, it is considered to be the best. All shells that have been resized should also be the same size.

To help you set any desired shell range, it should also be altered.

What are the best case trimmer brands?

There are a few well-known brands that produce high-quality case trimmers. For example, Hornady makes a very popular case trimmer called the Lock-N-Load Case Trimmer. This particular model is very easy to use and produces consistent results.

Another well-regarded brand is Lyman brand. Lyman also makes a great case trimmer called the Universal Case Trimmer. This model is a bit more expensive than the Hornady, but it comes with a number of features that make it worth the extra cost.

Frankford Arsenal is another high-quality case trimmer brand. Their Platinum Series Case Trimmer is a great choice for those looking for a top-of-the-line model. This trimmer features a number of helpful features, such as adjustable stop collars and a built-in deburring tool.

Forster products are also known for being high quality. Their Benchrest Case Trimmer is a great option for serious reloaders who are looking for the best possible accuracy.

Finally, RCBS also makes a high-quality case trimmer called the Rock Chucker Supreme Press. This press is designed for reloading ammunition and can be used to trim cases as well.

What types of case trimmers are there?

Case trimmers come in a variety of forms, dimensions, patterns, hues, and varieties. Check out the following to learn more about the types of case trimmers available currently on the market:

Fixed-adjustment

It has a straightforward design and only accommodates one size. Therefore, it cannot be used to resize bullets of various calibers. But they are inexpensive due to their simplicity and limitations.

Low-volume precision

This case trimmer features a stand mechanism for a better trimming experience.

Do not be misled by the word “low-volume”; this trimmer can outperform well-known models like the Lathe kinds in terms of speed.

It is not the best option for a newbie because setting it up is a hassle. Additionally, it’s not ideal for a shooter who employs bullets of various calibers and sizes.

Lathe type

It is the most popular kind and has a holder to aid in clamping the bullet. To trim the bullet, its cutter is positioned on the trimmer’s opposing side.

It can be adjusted to resize coarse to fine shells despite being quite quick, however you should select a slower speed for accuracy.

On-press trimming

It is the quickest method for shell trimming and deburring. But in order for it to function correctly, you need a reloading die with a full-length size. It is also incredibly bulky and makes a lot of noise.

Shoulder-indexing

This is one of the more expensive trimmers, but it’s also the most precise.

Shoulder-indexing

It has an indexing collar that moves in set increments, so you can get an exact measurement every time. It’s great for reloaders who want to achieve consistent results.

It is ideal for resizing many cartridges at once. The machine is simple to operate because of the flexibility of the chips. Case-length variations are not the best candidates. [2]

Can the cases be changed with ease?

Here, we look at how long it takes and how straightforward it is to go from one trimmed case to the next untrimmed case. It is desirable that cases can be changed quickly and easily. If there are only a few examples, this element can be somewhat disregarded; however, this cannot be said when there are many cases that need to be trimmed.

Is the cut clean?

This is probably the most important criterion. A clean cut will mean that there is less work to do in preparing the brass for reloading. It also indicates that the trimmer is likely to have a good, sharp cutting blade that is correctly aligned. If the cut isn’t clean, it can damage the brass and make it difficult to reload.

Other available functions besides trimming

Some brass case trimmers also come with other functions that can be very useful for reloaders.

For example, some trimmers can chamfer and deburr the mouths of cases at the same time that they are trimming them. This can save a lot of time when reloading because it eliminates the need to perform these two operations separately.

Another handy feature that some brass case trimmers have is the ability to prime cases while they are being trimmed. This is a great time saver because it means that you don’t have to prime your cases after they have been trimmed.

Finally, some brass case trimmers come with built in scale weighing systems. This can be very helpful for making sure that your cases are all the same weight which is important for consistent accuracy.

How easy is it to set up the case trimmer for precision trimming?

There are trimmers that you can set up in about two minutes, while others require more than five minutes only for the setup. When you just have one case trimmer and a variety of cases to trim, this factor really shines. But if you want to encourage a friend to start a comparable firm, I think this aspect is the least significant. He shouldn’t have to wait more than five minutes for the setup, under any circumstances.

When Small Changes Matter: Why Do We Need Case Trimmers?

We all know the saying “the devil is in the details.” Nowhere is this more true than when reloading ammunition. Every component in your reloaded rounds must meet strict tolerances or you risk a dangerous malfunction.One of the most important components of a round is the case.

The case needs to be exactly the right size to ensure proper function and safety.<
This is where brass case trimmers come in. A brass case trimmer is a precision tool that removes small amounts of brass from the case, ensuring that it meets the correct specifications. While this may seem like a small change, it can make a big difference in the performance and safety of your ammunition.

How to set up the Trimmer?

Most trimmers will come with specific instructions on how to set them up. If you don’t have the instructions handy, don’t worry. Setting up a case trimmer is usually pretty straightforward.

First, you’ll need to determine what size shell holder you need. This will be based on the caliber of brass you’re working with. Once you have the correct size shell holder, insert it into the trimmer.

Next, adjust the cutting blade so that it’s flush with the top of the shell holder. You can do this by loosening or tightening the screws that hold the blade in place.

Now it’s time to test the trimmer on a piece of scrap brass to make sure everything is set up correctly. Place the brass in the shell holder and pull the handle to operate the trimmer.

If everything looks good, you’re ready to start trimming your brass!

Things to keep in mind when using a case trimmer

  • Be sure to use the correct size die for your brass. Using a die that is too small will result in an undersized case, while using a die that is too large will result in an oversized case.
  • If you are trimming cases that have already been fired, be sure to clean them thoroughly before trimming. Any dirt or debris on the case can cause the trimmer to damage the case or produce an inaccurate cut.
  • Do not force the handle, let the cutter do the work.
  • When setting up the trimmer, be sure to follow the manufacturer’s instructions carefully.
    Incorrect setup can damage cases or produce inaccurate cuts.
  • Be sure to use sharp cutting blades. Dull blades can damage cases and produce inaccurate cuts.
  • Take your time when trimming cases. Rushing the process can result in damage to the case or an inaccurate cut.
  • Cases should be deburred after trimming is completed.
  • Trimmed cases should be full length resized before reloading.
  • Always use eye protection.
  • Be careful not to cut yourself on the blade.
  • Keep your fingers clear of the cutting area.
  • Trimmed brass can be sharp, so handle with care.

With these tips in mind, you should be able to get the best results from your case trimmer.

FAQ

What is the fastest case trimmer?

The fastest case trimmer is the one that can be used with a power drill. This type of trimmer can trim cases very quickly, making it a great choice for high volume shooters.

How important is brass trimming?

Brass trimming is important because it helps to ensure that your brass cases are the correct size. Trimming ensures that your cases are the same length, which makes them easier to load and prevents jams. It also helps to remove any burrs or imperfections on the case so that it will function properly in your firearm.

There are a few different ways to trim brass cases, but the most common is using a case trimmer. A case trimmer is a tool that helps to quickly and easily trim brass cases down to size.

Is case trimming necessary?

One of the most common questions we get asked is whether or not case trimming is necessary. The answer to this question depends on a few factors.

Firstly, are you reloading for accuracy or just plinking? If you are only shooting for fun, then case trimming is probably not necessary. However, if you are trying to get the most accurate shots possible, then trimming your brass cases can help to improve the consistency of your loads.

Another factor to consider is what type of firearm you are using. If you are shooting a revolver, then case trimming is generally not necessary as the brass cases will be supported by the chamber walls and will not need to be trimmed down.

On the other hand, if you are shooting a semi-automatic rifle, then case trimming is generally recommended as the brass cases need to be of a consistent length in order for them to function properly in the firearm.

So, as you can see, there is no simple answer to the question of whether or not case trimming is necessary. It really depends on your individual needs and preferences. However, if you are looking to get the most accurate shots possible, then we recommend trimming your brass cases.

What is a case trimmer used for?

A case trimmer is used to trim the brass casing down to a uniform length. This is important because it ensures that each round will fit into the chamber of your firearm correctly. It also helps to prevent jams and misfires.

There are a few different ways that you can trim your brass cases. You can use a manual trimmer, an electric trimmer, or even a lathe. However, the most popular method is to use a case trimmer with a power drill.[3]

Case trimmers come in a variety of sizes and styles. Some are designed for specific calibers while others can be used for multiple calibers. There are also some that are universal and can be used on any type of brass case.

Does the Case Trim Length Affect Accuracy?

This is a common question among reloaders. The simple answer is yes, the case trim length can affect accuracy. The reason for this is that when a bullet is seated into the case, it pushes on the back of the case. If the case isn’t trimmed to the correct length, this can cause the bullet to be pushed forward slightly, which can impact accuracy.

That being said, as long as you are consistent with your trimming length, it shouldn’t have a major impact on accuracy. So, if you’re using a brass case trimmer that has an adjustable stop, make sure you adjust it so that all of your cases are trimmed to the same length.

Another thing to keep in mind is that different brass case manufacturers have different tolerances for case length. So, you may need to trim your cases a bit more or less depending on the brand of brass you’re using.

If you’re looking for the best possible accuracy, it’s always best to err on the side of trimming your cases a bit too short, rather than leaving them too long.

Finally, if you’re reloading for competition, there are usually strict rules about case length. So, make sure you check the rules of the competition before trimming your cases.

Does Pistol Brass Need Trimming?

The answer is maybe. It all depends on the gun you’re shooting, how often you shoot, and what kind of brass life cycle you want.

If you’re a casual shooter who only goes to the range a few times per year, then it’s probably not necessary to trim your brass. However, if you’re a serious shooter or reloader who wants to get the most out of their brass, then trimming is definitely something you should consider doing.

There are a few main reasons why people choose to trim their pistol brass:

  • To increase accuracy – trimmed cases will fit more snugly in the chamber, which can lead to increased accuracy;
  • To increase brass life – trimmed cases will last longer since they’re not being forced into a chamber that’s too small for them;
  • To make reloading easier – trimming your brass will make it easier to resize and deprimer during the reloading process.

If any of these reasons resonate with you, then trimming your brass is definitely something you should consider doing. In this guide, we’ll show you some of the best brass case trimmers on the market so you can choose the right one for your needs.
