Today, the .45-70 retains its popularity due to several factors. Its inherent accuracy potential makes it suitable for both target shooting and long-range hunting. The cartridge’s substantial knockdown power is highly effective for taking down large game. The .45-70’s versatility is enhanced by the availability of diverse bullet weights and types, enabling shooters to tailor their loads for specific purposes. This versatility includes options for both black powder and smokeless powder loads, further expanding its range of application. Furthermore, the cartridge’s iconic status and the availability of numerous modern rifles chambered for the .45-70 contribute to its ongoing popularity.

Hodgdon, a name synonymous with quality and performance in the reloading world, has been a cornerstone for reloaders for decades. Their commitment to providing a wide range of powders, coupled with detailed and reliable load data, has earned them the trust of experienced reloaders and those new to the craft alike. Hodgdon’s powders are manufactured to strict standards, ensuring consistent performance and minimizing variations that can affect accuracy and safety. They provide reliable load data for a variety of cartridges, including the .45-70. Utilizing quality powders is crucial for achieving optimal performance and safeguarding against potentially dangerous pressure spikes.

Essential Knowledge for Optimal Reloading

Before embarking on the reloading journey, understanding the fundamentals of this process is necessary. The process involves several critical steps, each of which contributes to the quality and safety of the final product. Familiarizing yourself with the key equipment is paramount for anyone reloading. Here are the essential items that should be in your reloading setup:

Reloading Press: This is the heart of the operation, used to size, prime, and seat bullets. A sturdy press designed to handle the .45-70’s large cartridge is crucial.
Reloading Dies: These are specific to the .45-70 and comprise the sizing, seating, and crimping dies.
Digital Scale: Accuracy is essential. A digital scale provides precise measurements of powder charges. A beam scale is a viable alternative.
Powder Measure: Used to dispense accurate and consistent powder charges into each case.
Priming Tool: Used to insert new primers into the primer pockets of the cases.
Calipers: Used to measure case lengths, bullet diameters, and overall cartridge lengths (COAL).
Loading Block: Holds the cases upright during loading.

The choices made during the reloading process will heavily influence the performance of your rounds. Bullet weight and type, powder selection, and primer choice are all critical factors. Reloaders should always prioritize safety by working in a clean, well-lit area and adhering to established reloading manuals.

Hodgdon’s powders offer reloaders a wide range of options for tailoring their .45-70 loads. The selection of the right powder is key to achieving specific performance goals.

H322: H322 is known for its accuracy and consistent performance, often favored for moderate-velocity loads. This powder is ideal for a wide range of bullet weights and applications, from target shooting to hunting.
H4895: H4895 is a versatile powder that has a good track record for accuracy. It is suitable for a wide range of bullet weights in the .45-70 and will often deliver good results in modern lever-action rifles. This powder is known for its temperature stability, and its performance remains consistent across a variety of environmental conditions.
BL-C(2): This ball powder is suitable for those who want to use loads that will be optimized for a variety of bullet weights. It’s also a good option when the reloader aims to achieve a balance between velocity and accuracy. This ball powder is known for its high density, and it helps in achieving consistent measurements.
LeverEvolution: Hodgdon’s LeverEvolution powder is specifically designed for lever-action rifles. It’s formulated to deliver high velocities with heavy bullets, making it an excellent choice for hunting.

Navigating the Load Data Landscape

Obtaining reliable load data is essential for the .45-70 reloading process. These values will come from sources like the Hodgdon website and reputable reloading manuals. It’s important to always consult a current source and double-check all information. Never start loading without knowing the safety guidelines. Always start at the minimum suggested powder charge and gradually work your way up, carefully observing the behavior of each load. A safe approach is crucial to prevent catastrophic failures.

The table below will provide starting points for several Hodgdon Powders with a variety of bullet weights and types. This information is based on data available from Hodgdon and other reputable sources. Remember that this is a guide, and specific results may vary based on your equipment and the specifics of your rifle.

When selecting components, choose bullets appropriate for your intended use. A bullet designed for hunting will differ significantly from one for target shooting. Follow the manufacturer’s recommendations for primers and cases. Use a consistent case length across all loaded rounds. Carefully consider your rifle’s specifications when determining COAL.

Working Up a Safe and Effective Load

Before beginning the reloading process, ensure you have a clean, organized workspace and all the necessary equipment readily available. Here’s a breakdown of how to approach working up a load:

Choosing the components for your reload is the first step. Identify your ideal bullet weight and style. Select the right primer for your cartridge and powder. Use a source to find appropriate load data for your chosen powder and bullet. Follow the published guidelines to get started.
Once you have the components you will start preparing the cases. After the cases are cleaned and inspected, resize the cases, and then trim the cases to the correct length, if necessary. After this process, the primer pockets of the cases will need to be cleaned. Make sure that your cases are properly primed.
Next, dispense a small amount of powder in your case using the powder measure and powder scale. Carefully weigh each charge, beginning with the starting load. A crucial step is seating the bullet. Place the bullet on the case and carefully seat it using your seating die. Use the COAL recommended. After you do all of this, you can start the process of working up the load.
Begin by loading a few rounds using the starting load. Visit the range with these rounds and take the necessary measures. Keep track of your velocities. Note any signs of excessive pressure.
With each subsequent trip to the range, increase the powder charge in small increments, monitoring the cases for any unusual signs. Look for flattened primers, expanded case heads, or other indicators of excessive pressure. Always stay within the maximum loads specified in the manuals.

Troubleshooting and Common Issues

Even with careful planning, reloaders may sometimes experience issues. Here’s how to troubleshoot common problems:

Inconsistent Velocities: Velocity variations can be due to several factors, including improper powder measurement, inconsistencies in the primer, or even variations in the bullet.
Failure to Feed/Eject: This is often a function of incorrect COAL or issues with the rifle itself. Ensure all your rounds are properly prepared.
Accuracy Issues: Poor accuracy can be caused by many factors, including bullet selection, COAL, and inconsistencies in powder charge. The shooter’s abilities also play a role.
Pressure Signs: Be sure that you know the signs. Flat or pierced primers, case head expansion, or other changes are signs of dangerous pressure.

To address these problems, always double-check your measurements, consult with experienced reloaders, and refer to reliable reloading manuals.
