Finding 45-70 brass for sale that meets your needs is crucial. This guide is your comprehensive resource for navigating the world of 45-70 brass, ensuring you can keep your favorite lever-action or single-shot rifle singing.
Why Quality Matters When Purchasing Brass
The foundation of any successful reloading project is a deep understanding of the materials you’re working with. In the realm of ammunition, the cartridge case is a critical component, serving several essential functions.
The cartridge case is the backbone of the round. It houses the propellant, protects the bullet, and provides the structural integrity necessary to withstand the enormous pressures generated when the cartridge is fired. The case must be strong enough to contain the expanding gases, yet flexible enough to allow for reliable extraction after firing. It’s a delicate balance, and the material used plays a major role in achieving it.
Brass, an alloy of copper and zinc, is the material of choice for the vast majority of cartridge cases, and for good reason. It offers a superb combination of qualities: it’s relatively inexpensive, highly malleable, and exhibits excellent resistance to corrosion. Most importantly, brass possesses the necessary elasticity to expand under pressure within the chamber of the firearm, then contract again after firing, facilitating easy extraction. This expansion and contraction cycle is the heart of how reloadable cartridge cases function.
While the basic design of a cartridge case may appear straightforward, there’s a considerable degree of variation in the manufacturing process and the resulting quality. Choosing inferior brass is a recipe for problems, ultimately impacting safety, accuracy, and longevity.
High-quality brass is manufactured with a rigorous attention to detail. Consistent wall thickness is paramount, ensuring uniform bullet seating and predictable internal ballistics. Improper wall thickness can lead to erratic pressures, which in turn, can compromise accuracy and, in extreme cases, cause dangerous malfunctions.
Proper annealing is also critical. Annealing is a heat treatment process that softens the brass, making it more pliable and less prone to cracking during the reloading process. Brass that hasn’t been adequately annealed can develop splits or cracks, potentially causing a catastrophic failure of the case.
Dimensional accuracy is another key factor. Cases that don’t meet precise dimensional standards can lead to a variety of issues, from poor chambering to inconsistent bullet seating. Precision in manufacturing ensures consistent performance and contributes significantly to accuracy.
Poor quality brass can lead to a variety of problems. The most obvious is case failure: splits, cracks, or even complete separations. Such failures can render your firearm unusable and, in the worst case scenarios, pose a safety risk. Inconsistent pressures stemming from poor brass quality can result in wild swings in velocity, severely impacting accuracy.
Ultimately, investing in good quality 45-70 brass for sale is an investment in your safety and the overall performance of your ammunition. It is an important step to ensure the longevity of your favorite firearm and the safety of every shot fired.
Key Specifications and Dimensions: Matching Brass to Your Firearm
The 45-70, though a relatively simple round in concept, comes with a number of specifications and dimensional standards. These are critical in ensuring that the brass cases fit properly and function safely in your rifle.
The standard 45-70 case length is typically around 2.105 inches, although slight variations may exist. The rim diameter is around 0.607 inches, and the overall case diameter just forward of the rim is roughly 0.505 inches. These seemingly small measurements are actually very critical.
Matching the brass to the specific firearm is essential. Variations in chamber dimensions can occur, even between firearms of the same model and make. Before purchasing any significant quantity of brass, it’s always advisable to measure a fired case from your specific rifle to ensure the cases you buy will function correctly. This can prevent any problems with extraction or feeding, and therefore, potential safety issues.
Understanding these dimensions, or at least having some familiarity, is a vital step in ensuring the proper functioning and safety of your firearm. Always consult reloading manuals and take the time to verify that the brass you select is compatible with your rifle. If in doubt, consulting a knowledgeable gunsmith or experienced reloader is always a wise move.

Gun Shows and Auctions
Gun shows and auctions can be fruitful hunting grounds, but require extra care. You can sometimes find great deals on 45-70 brass for sale at gun shows and online auctions. However, buying used brass requires a thorough inspection to avoid purchasing damaged or worn-out cases. Be sure to closely examine each case for splits, cracks, or any signs of wear.
Key Considerations When Purchasing 45-70 Brass
Brass Quality
Before you click that “add to cart” button, take a moment to consider the factors that will determine the quality, value, and suitability of the 45-70 brass for sale you’re considering.
Quality, as discussed earlier, is paramount. Pay close attention to the manufacturer’s reputation, and read reviews from other reloaders. Brass from reputable manufacturers generally undergoes more stringent quality control, which translates to more reliable performance.

New vs. Once-Fired Brass
Finally, the choice between new and once-fired brass. New brass is, of course, pristine and ready to load. Once-fired brass offers a lower price point but may require more cleaning and inspection. The initial cost of new brass is more, but the potential for better and longer life in reloading is high.
