The .45-70 Government, also known as the .45-70, was initially developed for the U.S. Army in the 1870s. Designed as the standard issue cartridge for the Springfield Model 1873 rifle, the round quickly became legendary. Its large-caliber bullet and significant gunpowder charge delivered considerable stopping power, a necessity in the often chaotic environments of the era. From the battlefields to the hunting grounds, the .45-70 became a staple.
Modern enthusiasts are still drawn to the .45-70. The cartridge provides a satisfying shooting experience. With proper load selection, it’s capable of taking down even the largest North American game. Target shooters enjoy the challenge of the round at long ranges, appreciating its inherent accuracy potential. Its resurgence in popularity is a direct result of its effectiveness and the wide availability of rifles chambered for it. Whether you prefer a classic lever-action, a single-shot sharpshooter, or a more modern rifle design, there is a .45-70 that’s right for you.
Why Choose Hornady Components?
Hornady stands at the forefront of ammunition and reloading component production. Their dedication to rigorous quality control, innovative designs, and commitment to providing consistent performance makes them a favored choice among reloaders. Hornady bullets, in particular, are famous for their precision manufacturing. Their bullets are often favored for superior accuracy and terminal performance on game. Features like the InterLock ring, a raised ring inside the bullet jacket, lock the core and jacket together, providing controlled expansion and excellent weight retention, all qualities that enhance the effectiveness of the .45-70.
The benefits of Hornady reloading components extend to their cases. Crafted from premium materials and manufactured to exacting standards, Hornady cases consistently deliver reliable performance and extended lifespan. The availability of these components is also a significant advantage. Whether you are a seasoned reloader or just starting out, you will have access to the necessary components to start using your **Hornady 45 70 load data** as a reference. Hornady also publishes detailed and updated reloading manuals, offering extensive data and guidance for safe and successful reloading.
Hornady Bullet Selection for .45-70
Common Hornady .45-70 Bullet Weights
The .45-70 is capable of handling a broad spectrum of bullet weights. The choice of bullet weight directly influences trajectory, downrange energy, and overall performance. Hornady provides bullets designed to match the many applications of the .45-70. Three are the most common, and each provides unique characteristics to tailor to the user’s specific needs.
**300 Grain Bullets:** These are generally the lightest bullets offered by Hornady for the .45-70, and excel in terms of velocity and flatter trajectories. 300-grain bullets work exceptionally well in lever-action rifles, and are favored for hunting deer and other medium-sized game. They offer a balance of speed and expansion, providing a devastating terminal effect at moderate ranges.
**325 Grain Bullets:** Falling into a mid-weight range, these bullets provide a nice blend of speed and energy. They are versatile, proving effective in both lever-action and single-shot rifles. These bullets, with the right loading, can provide excellent accuracy and can be used for hunting game of various sizes.
**350 Grain Bullets:** Offering a heavier bullet that provides a significant increase in energy, and can be used for heavier game, while still retaining decent trajectories. 350-grain bullets are favored for hunting larger game species like elk or black bear. They offer excellent penetration and retained energy, ensuring reliable knockdown power.
**405 Grain Bullets:** The heaviest bullet commonly used by Hornady for the .45-70. These are often used in single-shot rifles. With a slower velocity, these bullets provide the greatest amount of energy transfer upon impact, and are very effective on thick-skinned animals.
Bullet Construction and Design
The design of a bullet profoundly impacts its performance. The ogive, or the curved portion of the bullet’s nose, influences ballistic coefficient and drag. The meplat, or the flat tip of the bullet, affects expansion and terminal performance. The jacket, typically made of copper, encases the lead core, and controls expansion. The core itself influences weight, density, and expansion characteristics. Hornady leverages these design elements to create bullets that perform reliably and accurately.
Hornady’s advancements in bullet technology, especially their controlled-expansion designs, like the InterLock ring, dramatically improve performance. The InterLock ring mechanically locks the core to the jacket, resulting in more controlled expansion, increased weight retention, and deeper penetration. The FTX (Flex Tip eXpanding) bullet is another innovative design, particularly suited for lever-action rifles. Its soft polymer tip ensures a safe, reliable ignition while protecting against accidental primer detonation in tubular magazines, providing the benefits of excellent ballistic coefficient with enhanced terminal performance. Understanding these bullet construction features is critical when selecting the right **Hornady 45 70 load data** for your specific hunting or shooting needs.
Safety First!
The Importance of Safe Reloading Practices
Reloading can be a rewarding pastime, but it demands a commitment to safety. The potential for injury and damage to equipment is significant if safety procedures are not followed. Always prioritize safety, never take shortcuts, and double-check all steps.
- Always use a reliable reloading manual as a source of load data. The Hornady reloading manual is the go-to reference, but several reputable sources exist. Use data specific to your bullets, cases, and powders.
- Wear safety glasses and hearing protection at all times while reloading. Eye protection is essential to protect against flying debris or primer fragments.
- Start with the minimum recommended powder charge. Gradually increase the powder charge while monitoring for pressure signs (flattened primers, difficulty extracting cases, etc.).
- Never exceed the maximum powder charge listed in your reloading manual. Overcharging can cause catastrophic failures.
- Use proper reloading equipment. Ensure your scales, dies, and other tools are in good working order and correctly calibrated. Inspect your cases for any damage before reloading.

Tips and Considerations for Reloading .45-70
Proper case preparation, consistent powder selection, and precise seating depth are critical for achieving accuracy and safe reloading.
Case Preparation
- Trim cases to the correct length to ensure proper chambering.
- Deburr and chamfer the case mouths to promote smooth bullet seating.
Powder Selection
- Consider burn rate and velocity requirements.
- Consult reloading manuals for optimal powder choices.
Seating Depth
- Experiment with seating depth to optimize accuracy.
- Be aware that seating depth affects pressure.
Crimping
- Use a proper crimp.
- Consider the rifle design (lever action).
Testing and Optimizing Loads
- Use a chronograph to measure velocity.
- Shoot targets to evaluate grouping.
Firearms Compatibility and Applications
Lever-action rifles, single-shot rifles, and bolt-action rifles chambered in .45-70 provide different experiences and considerations.
Lever-action rifles, such as the classic Marlin models and Henry rifles, are a traditional pairing with the .45-70. Their tubular magazines often require the use of round-nosed or Flex Tip (FTX) bullets to prevent accidental primer ignition. Single-shot rifles, like the Ruger No.1 or the Sharps rifles, can safely handle the heaviest loads and heavier bullet profiles, offering the potential for extreme accuracy. Bolt-action rifles, if they exist, should have proper pressure ratings and are capable of the same loads as single-shot rifles.
Hunting Applications
The .45-70 is a powerful and versatile hunting cartridge, and the right Hornady bullet can maximize its effectiveness on game. For deer and medium-sized game, the 300-grain or 325-grain bullets offer a good balance of velocity and terminal performance. For larger game, such as elk, moose, or bear, the 350-grain and 405-grain bullets provide the necessary penetration and stopping power. Proper shot placement is critical, regardless of the bullet and game.
Target Shooting Applications
The .45-70 is also used for target shooting, and its accuracy potential is remarkable. The choice of bullet weight and design is essential for accuracy, and careful load development is also critical.
Where to Find Hornady Load Data
The Hornady reloading manual remains the definitive resource for accurate and up-to-date load data.
