The Hornady Bullet Comparator is a precision tool used by reloaders to ensure consistent bullet seating depth and overall cartridge length. Understanding its size chart is crucial for accurate and safe reloading. This guide will delve into the intricacies of the Hornady Bullet Comparator size chart, explaining its purpose, how to use it, and troubleshooting common issues.

Understanding the Hornady Bullet Comparator

The Hornady Bullet Comparator is a simple yet effective tool consisting of a body, a set of precisely machined bushings (the size chart refers to these bushings), and a measuring device (often a dial indicator). The bushings are what dictate the size of bullet that can be measured. Each bushing corresponds to a specific bullet diameter, allowing reloaders to accurately measure the bullet's base-to-ogive (the curved portion of the bullet) distance. This measurement is critical for consistent bullet seating and overall cartridge uniformity, leading to improved accuracy and safety.

Deciphering the Hornady Bullet Comparator Size Chart

Unfortunately, Hornady doesn't provide a publicly accessible, single, comprehensive "size chart" in the traditional sense. Instead, the sizing information is implicit within the individual bushing selection. You purchase bushings that correspond to specific bullet diameters. The key is to match the bushing's internal diameter precisely with the bullet's caliber. This is where careful attention to detail is crucial.

How to Find the Right Bushing:

  1. Identify your bullet's caliber: This is usually clearly marked on the bullet box or the bullet itself (e.g., .223, .308, 9mm).

  2. Consult your Hornady reloading manual or the specific product information for the Bullet Comparator: These resources often contain a list of available bushings and their corresponding bullet diameters. Accurate measurement using a caliper is essential here. Slight variations can lead to incorrect measurements.

  3. Select the appropriate bushing: Choose the bushing with an internal diameter that precisely matches your bullet's caliber. Using a bushing that's too large or too small will result in inaccurate measurements and could potentially damage your equipment or bullets.

Using the Hornady Bullet Comparator Effectively

Once you have the correct bushing, using the comparator is relatively straightforward. The process usually involves:

  1. Securing the bushing: Insert the chosen bushing into the comparator body and ensure it's securely fastened.

  2. Inserting the bullet: Carefully place the bullet into the bushing, ensuring it's seated correctly and firmly.

  3. Taking the measurement: Use the dial indicator to measure the distance from the bullet base to its ogive. This measurement is critical for consistent seating depth.

  4. Recording the data: Note down your measurements for later reference. This allows for consistent bullet seating in subsequent reloading sessions.

Troubleshooting Common Issues

  • Inaccurate Measurements: This could result from using the incorrect bushing, improper bullet seating, or a damaged or poorly calibrated dial indicator. Double-check all components and recalibrate the dial indicator as needed.

  • Bushing Damage: Avoid forcing bullets into the bushing. This could damage the bushing and lead to inaccurate measurements. If you experience any resistance, re-evaluate the bushing selection.

  • Difficulty Seating Bullets: If you are having trouble seating the bullets, you may be using the wrong bushing, or the bullets might have imperfections.

Conclusion

The Hornady Bullet Comparator is an invaluable tool for precision reloading. While a singular, readily available size chart doesn't exist, understanding how to select the correct bushing based on your bullet caliber and utilizing the comparator correctly is paramount to achieving consistent and accurate reloading results. Always consult your Hornady reloading manual and prioritize safety throughout the reloading process.
