Comparators & Concentricity Gauges for Sale – Improve Your Reloading Accuracy

If you want to achieve the highest level of precision in your handloaded ammunition, comparators and concentricity gauges are essential tools. These devices help measure bullet seating depth, overall case length, and round concentricity, ensuring that each cartridge is consistent and accurate.

Whether you’re a competitive shooter, long-range hunter, or serious reloader, these precision tools allow you to fine-tune your ammunition for maximum performance.

What Are Comparators and Concentricity Gauges?

Comparators

A comparator is a tool used to measure a bullet’s seating depth and case length to ensure consistency when reloading. Instead of measuring from the bullet tip (which can vary slightly due to manufacturing differences), a comparator measures from the ogive—the point where the bullet’s curve starts. This provides a more precise and repeatable measurement, improving accuracy.

Concentricity Gauges

A concentricity gauge checks how straight a bullet is seated in the case. If a bullet is off-center (out of concentricity), it can affect accuracy and cause inconsistent performance. These gauges help reloaders detect and correct any misalignment, ensuring a properly loaded round every time.

Why Use Comparators & Concentricity Gauges?

Reloading ammunition by hand allows for greater precision than factory-made ammo, but even small inconsistencies can impact accuracy. These tools help you:

✔️ Improve accuracy – Ensuring bullets are seated uniformly leads to better shot consistency.
✔️ Reduce bullet runout – Detect and correct misaligned bullets that could affect trajectory.
✔️ Extend case life – Proper measurements prevent overworking brass cases, making them last longer.
✔️ Fine-tune handloads – Match your ammunition perfectly to your firearm for superior performance.

If you’re serious about accuracy, these tools are a must-have for your reloading bench.

Types of Comparators & Concentricity Gauges for Sale

There are different styles of comparators and concentricity gauges available to meet every reloader’s needs.

Bullet & Case Comparators

How to Use a Comparator and Concentricity Gauge

Using a Bullet Comparator

1. Attach the comparator to a caliper.
2. Insert the bullet and measure from the ogive.
3. Adjust seating depth as needed for uniform measurements.

Using a Concentricity Gauge

1. Place the loaded cartridge into the gauge.
2. Rotate the case while checking the dial indicator.
3. If the bullet is off-center, use an adjustment tool to correct runout.

By following these steps, you can fine-tune your ammunition to achieve the best possible accuracy.
