Top Three Best Case Trimmer in 2019

Trimming cases is a job that every reloader looking to recycle their cartridges do. You can’t skip the job unless you’re up to purchasing a new one every time you load those bullets. And back in the days, you have no other ways than using a manual trimmer by turning your hand on the case that has been put on the holder.

It simply takes way too much time.

Seeing that the method isn’t exactly the most effective or maybe how your recent trimmer is probably losing its edge it used to have when you first had it, here’s the review you’ve been waiting for. The case trimmer you should get next for a better reloading experience!

How does a case trimmer work?

Various case trimmers work differently from each other. Almost all companies produce both the manual and automatic prep center. Manual case trimmer has a lock and handles turning system that has been made more convenient and precise. While the handles were initially made to be manually turned, they can be easily replaced with a driller to fasten the whole process.

Before trimming, one has to find the right case holder and size it by trimming one case before hand or follow the manuals that come with it. After you size the first case you trim, adjust it and there, you have got your trimming template. The case holder uses a sort of locking system by turning to loosen and tighten.

Lee trimming system is different in that it makes use of the reloading press. You only need to adjust the length of the screw and manually turns the handle to trim it. While a prep center is automated with three different trimmers. There’s a small adjustment needed depending on the length of the cartridge you want and the other two are for cleaning the mouth of the brass.

Top Three Best Case Trimmer in 2019

These 3 case trimmers have their own strengths and can depend on your own preferences. Each brand has a different type of case trimmers and you may have your own preferences or budget that you want to stand-by.

#1 Frankford Arsenal Platinum Series Case Trim and Prep System

The Frankford Arsenal is the best case trimmer that works differently and amazingly quick for us. It has 4 different functions. It trims, chamfers, deburrs and cleans your primer socket in 5 seconds. The whole set is portable and all the tools can be kept in the case that’s attached to the machine.

The Frankford Arsenal Platinum Series Case Trim and Prep come with the four mentioned tools, 3 collets, and 6 shoulder bushings to trim various cartridges into the sizes that you want.

Pros:

Quiet even though the machine turns three tools at once due to the fact that they are not necessarily turning like a drill, but at just enough speed to trim the cases at the right length. The rubber isolator at the feet also prevents vibration and dampens the noise.
Wide capability: Trims cases from .17 Remington to .460 Weatherby by adjusting the bullet with the right collet and shoulder bushing.
One template for all: After you get the right collet and bushing, you install it into the trim socket, lock it and adjust the length which has a visible mm knob.
4 functions at once: Other case trimmers come with only trimming but this prep center also has deburring, chamfering and even cleaning the primer sockets in one run.
The adjustable position allows you to work in the most convenient position for you. You can place it face up, horizontal or even turn it upside down; whichever works best for you!

Cons: The plastic structure can make it seem a bit flimsy and the chamfering, as well as deburring tools, seems to wobble slightly while they don’t really change the results that still make your bullets look smooth.

#2 Hornady 050140 Cam-Lock Case Trimmer

The case trimmer here works with brass from Hornady only and makes it the choice for those who use the brand. It has easy prep and no electricity needed, while it’s manual and has to be turned by hand. But it’s a great choice for those of you who look forward to simplicity (and budget!). Comes in red color.

The trimmer can be attached to the bench and comes with 7 pilots for various mouth sizes. Adjusting it is as easy as locking the brass on the right case holder and adjust the length of the trimmer so it’ll stop at the right point. The handle is designed to allow you to use your palm to turn the handle and trim. Rinse and repeat!

Pros:

Simplicity is the great thing about using case trimmers like this if you don’t like having machines work the job and trim too much before you see it.
Hand-drill (optional) can be mounted instead to trim them faster, just place it at the right position to get it to stand
Affordable compared to prep centers and also works with the case holders that you probably already have from Hornady.
Range – trims case mouth of various sizes with additional pilots can be bought separately.
Accurate and quick as it trims cases down to 1000^th of an inch and cycling each case is as easy as pulling out the trimmer, loosening the cartridge, and tighten them again.

Cons: You need the energy to turn the handle, something that automated machine can do without making your arm sore. While it can be changed to a drill, a driller is generally a little too fast and hot to trim a case. And you still need to chamfer & deburr them. Lastly, it’s strictly for Hornady’s brass only as you need the case holders of the same brand as well.

#3 Lyman Universal Trimmer with 9 Pilot Multi-Pack Trims .17 Cal to .458 Cal

Lyman Universal Trimmer works similarly to the Hornady’s. The major differences are in the color and the handle’s shape. While the Hornady’s shape is much like a flattened cone, Lyman’s uses a knurled handle which can be changed into a drill as well. It can also be attached to a power adapter which is sold separately. And it comes in the color of orange.

Similarly, Lyman trimmer case can be screwed to the bench as the offset is provided there. It comes with 9 different pilots instead of 7 to give even better precision depending on cartridge size. The brass is locked in place similar to the Hornady’s; loosening and tightening the brass by turning the lever can easily be repeated.

Pros:

Simplicity is the great thing about using case trimmers like this if you don’t like having machines work the job and trim too much before you see it.
Hand-drill (optional) can be mounted instead to trim them faster, just place it at the right position to get it to stand
Affordable compared to prep centers and also works with the case holders that you probably already have from Hornady.
Range – trims case mouth sizes from .17 to .458 and 9 pilots are included with this trimmer.
NO case holders! As opposed to the Hornady’s that requires them, this trimmer case is truly universal for any brass so long as they are within the range of the pilots available. Simply lock it in place and you are ready to go.
Accurate and quick as it trims cases down to 1000^th of an inch and cycling each case is as easy as pulling out the trimmer, loosening the cartridge, and tighten them again.

Cons: You need the energy to turn the handle, something that automated machine can do without making your arm sore. Additionally, the knurled handle is less effective than the Hornady’s. While it can be changed to a drill, a driller is generally a little too fast and hot to trim a case. And you still need to chamfer & deburr them.

Things to consider before choosing a case trimmer

Before you rush to the Amazon to get that new prep center or case trimmer, be sure that you’ve done a quick homework on them. They might not look that complicated, but choosing the right one will save you the pain of turning the handle hundreds of times while pouting or bewildered by the automated machine that seems to screw with your usually precise feelings.

BudgetBrandCapacityPersonal preferenceNoiseElectricityConvenience

With prep centers that runs on electricity and additional tools, you are expected to pay much more for a single device. It may cost 75% to twice the price of a trimmer case plus chamfering and deburring tools. You also need to think of the additional pilots that you need to buy for your brass.

Some trimmers are brand-specific, meaning you can’t use other trimmers on them. It could be because of the case holders or collets (which is often the only reason). If you use mostly Hornady’s products, you know that you’re not left with much choice but to use their trimmer tool. Or you can opt to get a prep center with suitable collets and shoulders brushing.

Comparably, prep centers trim, chamfer, deburr and clean prime sockets much faster than a simple case trimmer. This means you are preparing more in a short amount of time. At the same time, automatic chamfering and deburring may not be recommended for beginners as you may instead sharpen the mouth too much.

Some people love being able to turn the handle and feel the brass being cut. You can also see how far it goes and if it’s clean-cut, or still require a couple of turns. With a prep center, it may cut a little too much at times, but high-quality ones generally don’t let happen.

A trimmer case with a drill as the handle obviously makes much louder noise. A prep center on the other hand, not so much. This is because a prep center is not turning as fast as a drill; just enough to cut the brass quick. The Frankford that we recommended is also great for not making a loud noise considering there are 4 different tools turning at the same place.

Prep centers use electricity while turning handles don’t.

A prep center is a little more complicated to prepare at first as you need to attach the tools to the machine and then choose the right collet and shoulder brushing. You have to lock it at just the right tightness. While a case trimmer is simpler to use with the right size of pilots and case holders attached and the right gap of a brass length set up.

Advantages of Having a Case Trimmer

A lot of times, we see brass in much less good condition, but not at the size we want. Others might notice that the mouth is a little cracked and wants to salvage what’s left by trimming the cracked edge. Whichever it is, here’s a good reason to get a case trimmer:

No need to buy new cartridges
Trim within seconds, especially if you get a prep center, everything is in one place and you don’t need to buy separate tools or be bothered to manually put pressure on your hand while trimming.
Salvage unused cartridges, such as the ones that you found or have been shot before. After tumbling them, you can trim them for other uses or salvage brasses that you found in ranges.

Conclusion

Once you get your case trimmer, you’ll know how much time you will be able to save in the long-run. You don’t have to worry about buying new cartridges every time you want to reload. A case trimmer isn’t exactly costly considering the cutters and pilots can be used for a very long term.

The Frankford is the best value that we have to recommend due to how there are many tools available in a single device. The Lyman is our next favorite guy being a universal trimmer and trims a brass like a pro. The Hornady is a great addition for Hornady lovers and we love the handle shape that makes it easy to turn and trim with the palm of your hand.
