Best Case Trimmers – Buyers Guide

Brass cartridges get larger every time you fire them. This expansion can prevent it from fitting in the chamber after reloading your ammunition for reuse.

Case trimming lets you reload your ammunition multiple times without this problem. However, case trimming is one of those activities gun enthusiasts don’t always enjoy doing.

A case trimmer — along with a great reloading scale, die, caliper, tumbler, and press — is necessary for the consistency and accuracy of your hand loaded ammunition.

In this buying guide, you’ll learn what a case trimmer is, as well as the 6 best case trimmers on the market.

What is a case trimmer?

A case trimmer is a device that adjusts the length of your cases and makes it easier to chamber and extract ammunition.

Using a case trimmer makes the size of your rounds more consistent, improves accuracy, and prevents malfunctions. The right case trimmer increases the reliability of your ammo and keeps cases from jamming in the chamber.

Do I need a case trimmer for reloading? Yes, you need a case trimmer to reload your ammunition. Having the right trimmer lets you resize your cartridges for reloading. You also need a scale, die, caliper, tumbler, and reloading press.

Without a case trimmer, your cartridges may not fit into your reloading presses or even chamber correctly in your firearm. Cutting them down to the right size makes the reloading process more efficient.

Reloading spent ammunition is more cost-effective, and trimming cases is essential to getting the best results from all styles of presses: turret, single-stage, or progressive reloading press.

Are case trimmers caliber specific? Yes, many case trimmers are caliber specific. Some models, however, such as the Lyman Universal Trimmer, feature a universal chuckhead, which lets you trim caliber sizes between .17 and .458.

Other models like a fixed-adjustment case trimmer often support one size. This makes it difficult, if not impossible, to trim different calibers.

You could find a case trimmer that lets you change the size of the shell holder, which makes it possible to work with different caliber sizes.

When should you trim your cases? You should trim your cases before reloading your ammunition. Trimming your cases removes excess length that results from expansion. This allows your ammunition to properly fit into the chamber when you reuse it.

Case Trimmer vs. Case Prep Center

What is the difference between a case trimmer and a case prep center? A case prep center is like a case trimmer deluxe. It lets you trim, chamfer, deburr, ream, and clean. Think of it as an all-in-one option for gun enthusiasts.

You can attach different tools to a case prep station, many of which speed up the reloading process.

Case trimmers change the length of your casings before reloading your ammunition. A lather-type case trimmer lets you make adjustments and trim cases quickly.

A fixed-adjustment case trimmer is ideal for working with a single-size casing. However, this is a limitation for shooters who want to reload different caliber sizes.

On-press case trimmers trim and deburr ammunition in seconds. Unfortunately, this requires a full-length sizing reloading die, and many users find some models difficult to work with.

Low-volume precision case trimmers offer speed, but they can be challenging to set up.

Shoulder-indexing case trimmers make it easy to trim more ammunition in a shorter amount of time. However, it may not be ideal for someone trimming a variety of case lengths.

What is the best case prep center? The best case prep center is the Frankford Arsenal Platinum Series Case Trim and Prep System. Frankford made this all-inclusive case prep center using high-quality materials and with durability in mind.

The RCBS 90375 Trim Mate is another standout choice for the case prep center.

Go out and buy the best case trimmer for you!

You should now have a better idea about what kind of case trimmer best suits your individual needs.

Chamfering and deburring smooth out the case mouth after trimming. This lets you achieve the right shape. Choosing a case trimmer with deburring and chamfering functions makes trimming cases more efficient.

What is the best case trimming machine? The best case trimming machine is the Frankford Arsenal Platinum Series Case Trim and Prep System. It features a steel cutter, a high-speed motor, and an adjustable collet system for chamfering, cleaning, deburring, and trimming cases.

Choose a case trimmer with shell holders that match your caliber size or allow you to adjust to a variety of sizes.

What is the best case trimmer for trimming cases? The best case trimmer for trimming cases is easy to use and has all the features that match your shooting needs. You want a trimmer that’s fast, consistent, and accurate. I recommend the Frankford Arsenal or RCBS trimmers.

Slower models may not be suitable for you if you plan on reloading a high volume of ammunition.

Look for polishers, tumblers, and a storage box when buying a case trimmer. Choose a case trimmer with a deburring tool and other features that enhance the reloading process.

These 6 best case trimmers offer features that make reloading easy, efficient, and more affordable. You can find these case trimmers on Amazon and through other retail websites.
