You can stay assured that this particular machine’s cutters will remain sharp even after a million usages.

The HSS cutters are made of lightweight yet strong aluminum, and they’re also super hard, which makes them durable and helps them stay sharp for a long time.

The series is named arsenal because you’re getting everything you need in only one kit. It comes with a chamfer, trimmer, deburrer, and extra tools.

We loved the adjustable collet system that’s designed to be compatible with any shouldered case as long as they fall between 17 Remington-.460 Weatherby.

There are three output shafts, and they’re usable with any trimming tool or accessory.

No need to carry the bushings and collets in your hands anymore, the set comes with a storage box for you to arrange them neatly.

  • Manually operated, can be fitted with an adapter.
  • Comes equipped with the seven popular pilot sizes
  • Reshapes cartridges perfectly
  • Equipped with a micro-adjust cutter

Any professional hunter knows the importance of perfectly sized cartridges and the difference they can make with meeting the target.

Keeping that in mind, Hornady introduced the Cam Lock Trimmer, which specializes in reshaping fired rounds as if they’re entirely new.

Don’t assume that the precision will require extra care while working. The trimmer can make changes of 0.001” without moving the shell; its micro-adjust cutter plays a significant role here.

It’s a heavy-duty, durable, and precise trimmer with a replaceable cutting head. As the cutting head is made of steel, you don’t have to worry about it decaying.

The trimmer comes equipped with the seven popular pilot sizes: 38 cal, 45 cal, 22 cal, 30 cal, 270 cal, 6mm, and 7mm.

The 7pilot sizes offer fantastic flexibility with its lightweight construction. Even if you’re not very experienced, you can easily learn to trim cartridges using this trimmer.

The large diameter of the cutter also offers users more space and comfort while working. The dimensions of the machine are only 11 x 6 x 4 inches, and it weighs only 3 pounds.

If you have a small workstation and no place to store a large trimmer, you can try this one as it’s equally efficient as any larger tool.

It’s a manually operated tool, some users like running the trimmer with a hand crank as they get more control this way.

If you don’t want to use the machine manually, you can purchase the adapter separately. The adapter doesn’t cost very much and significantly saves time.

  • Excellent for daily use
  • Length can be adjusted up to a thousandth of an inch.
  • Cast iron construction

This is our first of three universal case trimmers from Lyman. Along with the standard cutting head, the trimmer comes with a carbide cutter.

If you like hunting but also want to save some money, this case trimmer is perfect for you. Like the other Lyman products, this one is also affordable and doesn’t require shell holders or case collectors for working.

Many hunters trim their cartridges daily and want a tool that can perform consistently every day. The nine pilots multi-pack will ensure exceptional precision every single day you work with it.

As the tool is highly adjustable, you won’t get bored or frustrated while working with it. You can adjust the length up to a thousandth of an inch, which helps you in making your cartridge good as new.

6. Lyman Power Adapter Trimmers

Highlighted Features:

  • Highly affordable
  • The universal trimmer can be upgraded to a power trimmer in a few seconds.
  • Can trim 250 cases per hour
  • Ideal for both right and left-handed users
  • Comes with a sharp cutting head

Many people claim this trimmer is the best one because of its low price. The claim is justified because you won’t find another tool of this standard at the same price.

Although you’re buying a universal trimmer, converting it to a power trim is just a matter of seconds. All you need to do is replace the original shaft with a power adapter drill and rod.

Updating to a power trip will allow you to work on different cartridges more precisely and quickly. The tool becomes so quick that you can trim a maximum of 250 cases in only an hour; nobody can do that manually.

We mentioned Lyman products so many times because they come with everything you need in the kit.

This kit is no different, everything you need for updating the universal trimmer to a power trim is included in the kit, and you don’t have to spend a penny for extra tools.

Along with the essential tools, users receive a detailed step-by-step guide for the upgrading process.

If you’re a left-handed person and often face difficulty finding a tool that’s ergonomic for you, don’t worry, Lyman has thought about you.

The power adapter trimmer is ergonomically designed for both right and left-handed people.

With its sharp cutting head, fairly large diameter, and durable construction, the case trimmer is recommended for both professional and amateur hunters.

It’s low-cost, but high quality and excellently designed. We couldn’t hope for a better trimmer at such a price.

7. LEE 90437 Deluxe QK Trim CASE

Highlighted Features:

  • Handheld case trimmer
  • Lightweight
  • Compact size
  • Easy to use
  • Cannot be upgraded to a power trim

Are you just getting started with shooting and hunting and want to try a trim case without investing in a professional-grade trimmer kit?

Don’t worry, Lee Precision has specifically made trim kits just for hobbyist hunters/shooters like you.

The QK trim case looks and feels different than anything else on the list. It’s simple, compact, and lightweight. If you trim only a fistful of calibers now and then, the tool is ideal for you.

The product comes with an individual die that you’ll find fitted in the reloading press of the machine.

You can get the same level of precision with the QK trim as you do with the other kits. Users just need to turn the crank, and they’ll get the cartridge trimmed enough for a whole year.

Unfortunately, you cannot upgrade this trimmer to a power trim. It’s wholly handheld and manually operated. Just place the cartridge into your trimmer, and start turning the handle.

The trimmer will automatically start working on the round you’ve just placed inside.

8. Lyman 7862210 Accutrimmer with 9 Pilot Multi-Pack

Highlighted Features:

  • Trims wide variety of cartridges from caliber .17 – .458 Win Mag
  • Requires shell holders
  • Compact and lightweight
  • Other brand’s shell holders can be used with it.
  • Ergonomic design

We will end our review with the most popular brand, Lyman. The trimmer can trim a wide variety of cartridges from caliber .17 – .458 Win Mag.

It requires shell holders for working and is less expensive compared to the other products we have reviewed here.

If you have a small workstation and would like a trimmer that works very well but takes less space, we recommend this one for you.

The dimensions of this trimmer are 10.5 x 4.9 x 3.8 inches, and it weighs only 14.1 ounces. You can even carry it from place to place if you’d like.

For the low price, you get nine pilots included in the kit. If you want to upgrade the universal trimmer to a power trim, you’ll have to use a shell holder set, which is sold separately.

We don’t recommend upgrading the accutrimmer because then you can buy the other Lyman case trimmers, which don’t require shell holders.

If you want to upgrade it but don’t have the money, you can try using shell holders from previous trimmers; they can even be from other brands.  Setting the length you want is the primary task you have to do before starting trimming.

You can set the height at 3006, 44mags, 357, 308, or 380. The maximum length of the trimming is 7.60 for this machine.

We liked the solid construction, slim body, and the ergonomic handle of this tool. Whether you’re left-handed or right-handed, you can use it comfortably.

Conclusion

We hope you have a clearer perspective now and have found the best case trimmer for your cartridges.

Every hunter and shooter has different styles, so they require different accessory accessories. Keep your budget in mind, and have fun on your next hunting trip with newly loaded precision rounds!
