Reloading calipers are vital because safety is of paramount importance when it comes to reloading. Reloading cartridges the wrong way is an excellent way to blow your gun, if not your hand.

Second to this consideration is reliability. A good reloader makes reliable ammo, and tools necessary to ensure your ammo is both safe and secure are digital calipers. These allow you to measure cases inside and out, both lengthwise and diameter. On top of that, you have to measure overall cartridge length. This ensures the bullet is loaded correctly, will chamber, and cycle reliably — all important considerations for reloaders.

Below are our recommendations for the 4 best reloading calipers on the market:

Hornady Digital Reloading Calipers

The Hornady calipers are purpose-built for reloaders and are quick and easy to use as well as being quite affordable.

The Hornady calipers are digital, and digital is the superior option when it comes to excellent measurements. They are easier to read and just as reliable as dial calipers. The only downside is the requirement of a battery. The LCD screen is ultra-large for easy and accurate readings, especially if you factor in the shadow cast by your reloading gear in many cases.

The Hornady digital caliper has a smooth and relaxed moving adjustment wheel, as well as a knob that locks the slide in place. The accuracy is within .02 MMS. This level of accuracy is critical in making ammo that runs reliably, shoots true and, most importantly, is safe to use.
