A Comparison of the 5 Best Case Trimmers for Reloading
Last update on 2021-09-21 / Images from Amazon Product Advertising API
How We Choose + Our Must-Have Features
Here are the features that you should take into consideration when shopping for a case trimmer.
Think of how much you’ll be reloading. If you won’t be using your case trimmer often, a steel cutter will be more than enough. But for high-volume reloading, we suggest you get a cutter constructed from carbide or something more durable.
If you plan on reloading different calibers, you should get a case trimmer that’s compatible with all your cases. It would be best to purchase a universal case trimmer so you can use them in the future in case you want to add more calibers.
Investing in something that you can use for a very long time is a wise decision. But it’s also wise to spend within your budget if you have one. Besides, there are plenty of affordable but reliable case trimmer brands out there.
Electric or Manual
This actually depends on your preference. But if you want your reloading done quickly, we suggest that you get an electrically-powered case trimmer.
This goes without saying, but we all want to buy something that’ll last for a long time. And we can never guarantee a product’s durability unless we use it. To save you time, we’ve gathered and summarized all the customer reviews for these case trimmer brands so you can compare and decide for yourself.
Ease of Use
Let’s admit it, trimming brass cases is a tedious task. But you can make it less exhausting by getting a machine that’s user-friendly.
Not all of us have a workshop or dedicated space for reloading. If you have one, you won’t have to worry about your case trimmer’s size. But if you don’t, make sure to get a portable case trimmer or one that fits in your reloading area.

Customers also mentioned how easy it was to assemble the machine and how consistent the RCBS was once it’s set up.
One thing that some customers complained about was that loading the shells into the universal chuck takes longer than most brands.
