Buying Guide of Digital Caliper for Reloading 2023

best reloading digital caliper

Now, for the buying guide. We want you to walk through the things you can use to determine how a caliper becomes the best one explicitly for reloading. Keep the following things in mind when judging a caliper, and you should get your one in no time.


When you’re getting a digital caliper, you want to avoid plastic. Stainless steel is the most suitable material for a caliper. Not only because it’s durable and robust, but also because it’s convenient and smooth to operate.

If the caliper doesn’t run smoothly or feels rough, measurement becomes an annoying thing to do. So, if you want your caliper to last a reasonable amount of time, we recommend choosing a steel caliper.


Calipers come in all sizes. So, what size is suitable specifically for reloading? If you intend to use the calipers explicitly for reloading, a device that can measure up to six inches is enough. However, with a few more bucks added to the budget, you can go for a caliper that can measure up to eight inches.

Units of Measurements

Some calipers only support imperial units, whereas some support metrics. The good news is that most digital calipers nowadays can offer you both of these units of measurement.

However, make sure that the device can function accurately in both these units. Sometimes calipers can lose their accuracy when you frequently switch from one unit to another.

Locking Screw

Check for the caliper’s description, whether it features a locking screw or not. A locking screw will allow you to lock the measurement. This way, you can note down a measurement even if you slip your hand and remove the object from the caliper.


No matter what you’re measuring, you want it to be precise. The accuracy level should be as low as 0.001” if you want precise measurements. The lower the accuracy rating of a caliper, the more accurate it is.


You’ll notice that not all calipers can measure step and depth. Some of them are limited to internal and external diameters. We recommend you go for a caliper that can measure depth and step, too, especially if you’re getting one for reloading.


Price is always a determinant factor when getting anything. You can get easily confused while getting a caliper because they come in all price ranges. So, which one should you go for?

Naturally, the higher your budget, the better quality you’ll get. But that’s not always the case. Some calipers are insanely expensive yet disappointing when it comes to durability. So, whether you’re going for an affordable option or an expensive one, make sure you’re purchasing an authentic product.

Additional Features

Try to get a caliper that’s waterproof and dust-proof. Besides that, the caliper should come with a protective case and a battery. Some will even offer you a spare battery with the package.  

Difference Between Digital vs Dial Calipers for Reloading: Know the Best One for 2023

Many people get confused about whether they should get a dial caliper or a digital caliper for reloading. While it completely depends on the user’s comfort, we would like to point out some features of both types of calipers to make the decision easy for you.

All About Digital Calipers for Reloading

  • Digital calipers feature an easy-to-read display and run on batteries.
  • They are more accurate compared to dial calipers.
  • You can lock the measurement you took. So, even if your hand slips and the object falls, the measurement stays locked.
  • Digital calipers also allow you to switch between units of measurement.
  • A copper plate under the display of a digital caliper features specific grooves. If these grooves get damaged, you won’t get precise readings using the caliper.

Details of Dial Calipers for Reloading

  • Dial calipers run on a rack and pinion system. The device features gears inside it that measure the objects.
  • If you drop your caliper, the alignments can get messed up.
  • Dial calipers don’t require batteries to run.

6 Easy Tips for Using Digital Calipers for Reloading (The Ultimate Guide 2023)

Tips for Using Best Digital Calipers For Reloading

If you’re a beginner and haven’t used a digital caliper for reloading before, read through the instructions for an overall understanding.

  1. First, you’ll have to monitor the caliper’s jaws. Bring them together, so they stay close. Look for any light passing through. If there is, you need to clean the jaws before using them.
  2. Make sure that all your ammunition has been cleaned thoroughly before measurement. Anything remaining on them may alter the findings.
  3. The outer jaw area is for measuring bullet lengths and diameters.
  4. The inner jaw area is for gaps and holes.
  5. Tightening the lock screw will prevent the jaws from wobbling and get a better grip on the object you’re measuring.
  6. Note the measurement that appears on display.
