A Look Back: The History of the 45-70 Cartridge
The Genesis
The story of the 45-70 cartridge begins in the late 1860s. The U.S. Army, recognizing the need for a more modern and effective cartridge, initiated a search for a replacement for its existing paper cartridge rifles. The result was a cartridge that, at the time, was groundbreaking. The specifications were straightforward: a .45-caliber bullet propelled by 70 grains of black powder. From this, the cartridge took its familiar name: 45-70.
Military Service and the Springfield Model 1873
The cartridge and its associated rifle, the Springfield Model 1873, were adopted by the U.S. Army. This weapon quickly became a mainstay of the American military, used in conflicts across the vast landscape of the American West. The rifle was a single-shot, breech-loading weapon that was simple to use and known for its reliability. The 45-70, with its heavy, slow-moving bullet, proved incredibly effective at long ranges. Soldiers and plainsmen alike quickly found that this new, powerful weapon could reliably take down game, at a distance.
Civilian Life and Legacy
Following its military service, the 45-70 found a new life in the civilian world. With the close of the frontier era, the cartridge transitioned into a popular choice for hunting. It quickly became a favorite among big game hunters, prized for its knock-down power and accuracy. It also found favor among target shooters who enjoyed the challenges and nuances of the cartridge.
Today, the 45-70 remains a popular choice. Modern rifles are chambered for this cartridge, and manufacturers continue to produce it alongside modern smokeless powder loads and, of course, *45-70 black powder ammunition*. This enduring appeal is a testament to the cartridge’s effectiveness and the powerful connection it forges between shooter and history.
Understanding the Power of Black Powder
Black Powder Basics
Before delving into the specifics of *45-70 black powder ammunition*, it’s essential to grasp the basics of black powder itself. This substance is the foundation of the authentic 45-70 experience.
Black powder, often also referred to as “gunpowder,” is a relatively simple but highly effective propellant. Its composition is a combination of three primary ingredients: sulfur, charcoal, and potassium nitrate (saltpeter). These are blended in specific proportions, and when ignited, create a rapid combustion that generates expanding gases, propelling the bullet down the barrel.
Grades of Black Powder
Several grades of black powder exist, each designed for specific applications. These gradations relate to the grain size of the powder. For example, FFg is often used in rifles like the 45-70. FFFg and smaller grain sizes are better suited to pistols or smaller cartridges.
Safety Precautions
Black powder is also a relatively dangerous substance if handled improperly. Safety is paramount when dealing with black powder. Always store black powder in a dedicated, approved container, far from any open flame or source of ignition. A well-ventilated space should also be employed. When handling black powder, it is a good idea to wear appropriate personal protective equipment, such as gloves. Any spills should be handled promptly. Always be aware of local laws and regulations regarding black powder storage and use.
Why Choose 45-70 Black Powder Ammunition?
Authenticity and History
The allure of *45-70 black powder ammunition* extends beyond mere historical significance. There are tangible benefits and a unique shooting experience to be found.
Firstly, black powder offers a remarkable degree of historical authenticity. Shooting a 45-70 with black powder recreates the shooting experience of the late nineteenth century. For history buffs and enthusiasts, this offers a powerful connection to the past. It’s a chance to step back in time, to experience the feel of a classic cartridge in its original form.
Recoil and Shooting Experience
Contrary to some misconceptions, recoil from black powder loads can sometimes be perceived as less harsh than that of smokeless powder loads. While the push is distinct, the slower burn rate of black powder and the heavier bullet typically used in 45-70 loads often result in a more gradual, less jarring recoil impulse. This can make for a more comfortable and enjoyable shooting experience, especially for those who are sensitive to recoil.
Then there’s the unique shooting experience itself. The signature cloud of smoke, the distinct smell, and the slower rate of fire all contribute to a unique and immersive experience. It’s a slower, more deliberate process that encourages a different type of shooting, focusing on technique and precision.
Hunting Applications
For some, *45-70 black powder ammunition* is used for hunting. While legal and suitable for many big game animals, ethical hunting depends on knowledge of the range limitations of the cartridge and the ability to make a clean kill. Always check local regulations and ensure your firearm is properly zeroed and sighted to ensure your bullets strike their target with accuracy and precision.
Components of a Black Powder Load
Choosing Cases
To load your own *45-70 black powder ammunition*, you need to understand the components. Each plays a crucial role in the overall performance and safety of the ammunition.
Selecting the appropriate brass cases is important. It is wise to opt for cases specifically designed for black powder use. These cases are usually built to withstand lower pressures and may have larger internal capacity to accommodate the powder charge. Choosing a case that has a large enough internal capacity is important for maintaining a certain amount of “compression.”
Primers and Powder
Primers are another critical element. These small, cup-shaped components contain a sensitive explosive compound. When struck by the firing pin, the primer ignites, initiating the burning of the black powder. For *45-70 black powder ammunition*, large pistol primers are a good choice for reliable ignition.
The obvious next choice is the black powder itself. Select an appropriate grade of black powder for your rifle. FFg is a common choice, and always consult a reloading manual for guidance on specific powder charges.
Bullets, Wads and Lubricants
Bullets for *45-70 black powder ammunition* are frequently cast lead bullets. These are available in various weights, typically ranging from 300 to 500 grains, and the shooter often has the ability to select a cast bullet design that best matches their needs. Proper bullet lubrication is critical for accuracy.
To separate the powder charge and the bullet, wads or over-powder cards are often used. These help to maintain consistent powder ignition and reduce fouling in the barrel.
Finally, quality bullet lubricant or grease is essential. Lubricant reduces friction as the bullet travels down the barrel, improving accuracy and minimizing fouling.
Reloading Your Own Ammunition: A Step-by-Step Guide
Safety First
Reloading *45-70 black powder ammunition* is a rewarding process, allowing you to tailor your loads to your specific rifle. However, safety must always be your top priority.
Equipment and Supplies
Begin by collecting all the necessary equipment. You’ll need a reloading press and appropriate dies, which are specific to the 45-70 cartridge. A powder scale for accurately measuring powder charges is an absolute necessity. You will also need tools for seating primers, seating bullets, and, if necessary, case trimming.
The Reloading Process
The reloading process is divided into several stages:
- **Case Preparation:** Start by inspecting your cases. Clean the cases thoroughly to remove any residue. If necessary, trim the cases to the correct length. Using a primer pocket cleaning tool removes any residue from the previous primer.
- **Priming:** Insert the primers into the case with a primer seating tool. Ensure they are seated firmly and flush with the base of the case.
- **Powder Charging:** Use your powder scale to carefully weigh out the proper amount of black powder. Pour the measured charge into the prepared case.
- **Wad/Card Seating:** If you are using a wad or over-powder card, carefully seat it on top of the powder charge.
- **Bullet Seating:** Place the bullet into the case mouth and use your bullet seating die to seat the bullet to the correct depth.
- **Crimping:** Crimp the case mouth securely. The proper crimp helps to maintain bullet alignment and prevent the bullet from moving during recoil.
Optimizing Your Black Powder Experience
