Fine-Tuning the Beast: A Hornady Guide to 7.62x39 Reloading

Safety: The Cornerstone of Every Reloading Session

Essential Safety Equipment

Before diving into the specifics of loading, let’s underscore the paramount importance of safety. Reloading is a rewarding hobby, but it demands respect for the inherent dangers involved. Mishandling components or ignoring safety protocols can lead to serious injury or damage. Make no mistake: you are solely responsible for your own safety and that of those around you.

Essential equipment is non-negotiable. Safety glasses must be worn at all times to protect your eyes from projectiles and potential debris. Gloves, ideally nitrile or similar, are crucial for handling chemicals and minimizing skin contact with powders and primers. A well-ventilated workspace is also essential, as the fumes from reloading can be harmful.

Equipment Inspection and Storage

Regularly inspect your reloading equipment. This includes the press, dies, scales, and any other tools you use. Look for wear and tear, cracks, or any signs of damage. This is especially important. A tool malfunction at the wrong time can be devastating.

Storage of components is equally critical. Powders and primers should be stored in a cool, dry place, away from any source of ignition. Keep them securely locked away, out of reach of children and unauthorized individuals. Follow all manufacturer instructions for safe handling and storage of these materials.

Reloading Vigilance and Measurement

Be vigilant for any signs of trouble during the reloading process. These include issues like double-charging cases with powder, using incorrect powder types, or improper seating of bullets. A double charge is one of the most dangerous errors, capable of causing catastrophic firearm failure. Develop a methodical approach, and never rush the process.

Accuracy in measurement is paramount. Invest in a high-quality digital scale to ensure precise powder charges. Use calipers to meticulously measure case length, overall cartridge length (COAL), and bullet seating depth. Accurate measurements are the foundation of safe and effective reloading.

Building Blocks: The Components You Need

Brass Cases

Understanding the components of a reloaded cartridge is essential before you begin. Let’s break down each element of the 7.62×39 load.

Brass cases are the foundation. These reusable containers hold the primer, powder, and bullet. Proper case preparation is vital for accuracy and longevity. Start with cleaning the cases to remove dirt and debris. Next, trim the cases to the proper length as specified in your reloading manual. Then, chamfer and deburr the case mouth to facilitate easier bullet seating.

Primers and Powder

Primers, the small, sensitive capsules, initiate the ignition process. These come in various types, and choosing the correct one is crucial. The 7.62×39 generally uses small rifle primers. Refer to your reloading manuals and specific load data for the recommended primer type.

The choice of powder is a critical decision. Different powders have different burn rates, influencing velocity, pressure, and accuracy. The ideal powder for the 7.62×39 balances burn rate, efficiency, and the characteristics of the Hornady bullet you select.

Powder Selection and Hornady Bullets

There are many excellent options for 7.62×39, and powders are available from a range of manufacturers. Some examples include powders such as Hodgdon BL-C(2), IMR 4198, Accurate 1680, and Alliant Reloder 7. Always consult reliable reloading manuals and verify the recommended powder with your chosen Hornady bullet weight.

The bullet, the projectile that flies downrange, is arguably the most exciting aspect. Hornady offers a diverse selection of bullets for the 7.62×39, each designed for specific applications. From match bullets to hunting bullets, each type is tailored to deliver optimal performance.

Consider the desired purpose of your rounds when selecting a Hornady bullet. If you are interested in target shooting, then consider Match bullets. If hunting is your intention, choose a bullet designed for controlled expansion and good penetration, such as the Hornady SST or InterLock.

From Raw Materials to Finished Rounds: The Reloading Process

Case Preparation and Priming

The reloading process is a series of steps, each of which is critical to creating safe and effective ammunition.

Begin by preparing your cases. This involves cleaning the brass, trimming it to the correct length, and chamfering and deburring the case mouth. This will ensure the cases accept the bullet, and it improves consistency.

Next, prime the cases. Place a new primer into the primer pocket. Use the appropriate tool to ensure the primer is seated properly.

Powder Charging and Bullet Seating

The next step involves powder charging. Use your calibrated scale to measure the correct amount of powder, based on the data you’ve selected. Carefully pour the powder into the case. Consider using a powder funnel to minimize spills.

Seat the bullet. Carefully place the bullet into the case mouth, ensuring it is aligned properly. Slowly seat the bullet to the correct COAL using a seating die.

Crimping and Inspection

Crimping is often the final step. A proper crimp helps ensure consistent bullet pull and reliable performance. Use a crimping die to apply the proper amount of crimp.

Before taking your reloads to the range, visually inspect each round for defects. Measure the COAL to ensure all rounds are consistent.

Testing and Fine-Tuning: Bringing it all Together

Range Testing and Group Size

Range testing is where the fruits of your labor are realized. Choose a safe and appropriate range. Shooting and accurately hitting the intended target is not only rewarding but gives you invaluable data on the effectiveness of your load.

Before you start shooting, inspect your rifle and make sure it is clean and properly maintained. Begin by shooting your rounds at a target. Observe the group sizes and the point of impact. Make small adjustments to your loads to optimize the group size.

Chronographing and Data Analysis

A chronograph is an invaluable tool for assessing the performance of your reloads. Use a chronograph to measure the muzzle velocity of your rounds. Compare the measured velocity to the data listed in your reloading manual.

Observe the spent cartridge cases carefully. Look for signs of overpressure, such as flattened primers, difficult extraction, or expanded case heads. If you observe any of these signs, stop reloading immediately and reassess your load data.

Troubleshooting and Refinement: Addressing Common Issues

Accuracy issues are often related to one of these factors: bullet selection, powder choice, seating depth, or rifle setup. Experiment with different bullet weights and powder types to fine-tune your load. Adjust the seating depth of the bullet in small increments to see how it affects group size.

If you notice inconsistent velocities, investigate the powder charging process. Make sure your powder measure is calibrated correctly, and that you are using consistent technique. Pay attention to seating depth. A bullet seated too deeply can affect the internal case volume and lead to erratic results.
