Top Calipers for Reloading – Buying Guide

Let me elaborate on some of the key buying factors for your convenience.

Construction and Durability

When it’s all about durability, the overall construction needs to stand out for any calipers.

You don’t want any fragile unit that might break if it drops down or you sit on that. On top of that, you don’t want to buy a caliper each year. So, it’s vital for the unit to have solid construction.

If the frame of a caliper is made from stainless steel without any plastic involvement, it’s an indication of a long-lasting unit.

Measuring Modes

All the calipers offer multiple measuring modes. That’s nothing new. However, for reloading, you must go for the one that includes millimeter measurement mode.


Both accuracy and precision are crucial factors for a caliper. A minimum of 0.02 mm or 0.001 inches accuracy is expected from a top-notch reloading caliper.

Relative Zero

This is important if you reload different sizes and thicknesses of cartridges, which I believe you do for sure if you reload regularly.

To find out the measurement smoothly, the caliper must get back to zero quite easily against each attempt.

Easy to Calibrate

As per the standard practice, a dial caliper needs to be calibrated once in a year to verify the stated accuracy specifications.

To achieve that smoothly, the calibration should not be a complicated process because of the caliper’s complex design.


You will want to use a caliper both indoors and outdoors. That’s why it needs to be weatherproof.

At least it should be protected from dust ingress and water splash. An IP54 rating is enough for a caliper to consider it to be a safe unit.

Battery Life

Battery life is another vital factor for digital calipers. It has nothing to do with the dial calipers.

Any top-notch digital caliper should provide at least 1-2 years of battery life against regular use.

The cheap Chinese ones fail in this regard measurably.

Not only the battery life, but the battery compartment should not be a flimsy one.

What are the Different Types of Calipers?

Although the digital caliper is the most popular type of caliper amongst the reloaders, the dial calipers are not too far away from its digital counterpart in terms of user acceptability.

Let me brief a bit about these two types.

Digital Calipers

A digital caliper is the most popular type of caliper among the reloaders. It’s because a digital caliper gives a more accurate result, and it’s more beginner-friendly.

In the case of a digital caliper, a digital sensor gives the measurement information, that’s why it doesn’t get hampered by human movement.

You can easily see the digits through the LCD screen, use the buttons to switch between different measuring modes, on-off the unit, etc.

Dial Calipers

When it’s about comparing durability, a dial caliper tends to last longer than a digital caliper.

The significant advantage of dial calipers over digital calipers is a dial caliper doesn’t require any battery to operate. So, you don’t have to worry about battery life and all these.

Final Verdict

In this best calipers for reloading article, I’ve tried to list down some of the top-most calipers (both dial and digital) of various price ranges.

It’s quite evident that the budget ones don’t provide the same quality as the comparatively pricey ones do.

So, finally, it’s your preference. It’s always what you get is what you pay for.

If you don’t want to sacrifice the quality, durability, and performance at all, then either the iGaging or the Mitutoyo is the best bet for you.
