Brass 45-70
Brass 45-70 (Large Rifle primer) 2.095″-2.102″ O.A.L.
Brass 45-70 has been tested at elevated pressures suitable for Magnum Heavy Hunting Loads in adequate gun systems. When loading with black powder, annealing of mouth may be necessary to allow case to properly seal chamber due to lower pressures generated by these loads. The case is produced very strong to withstand high pressure loads associated with smokeless hunting loads and since the only way to make brass harder is to work the material Starline’s only option is to leave them stiffer so the customers can anneal for specific application.
For reloading purposes, competitive shooters and game hunters choose to use Winchester Unprimed Brass Rifle Cartridge Cases – 50/box because these cases offer the highest level of accuracy and performance possible. The production process that the company uses is quite regimented and is designed to create the highest quality cases that can be found.
As a result of the annealing process, there is a possibility that the cases will have a faint stain in the area close to the neck. It is possible for cases to arrive with round mouths that are not perfectly round due to shifts that occurred during the manufacturing process or the shipping process. Because of this, Winchester cautions its customers that these cartridge cases need to be sized, deburred, and chamfered before they can be loaded.
Hornady produces brass with the same precision, attention to detail and focus on perfection that has made them a world leader in bullets. They measure their brass for consistent wall concentricity, tests pressure calibration to ensure uniform case expansion and hand-inspects each piece.
This dedication to quality ensures proper seating of the bullet both in the case and in the chamber and consistent charges and pressures. The result is optimal velocity and repeatable accuracy from your cartridges. New, unprimed brass. This is not loaded ammunition.
Brass 45-70 Preparation
With bulk rifle brass you may sometimes notice a few case mouths are “out of round” or slightly dented below the shoulder. These imperfections occur in the final tumbling wash operation after the case mouth has been annealed. Brass manufacturers are aware of the case cosmetics and have worked to mitigate it, but due to equipment design, denting may still occur. Minor dents are normally removed in the first firing and will not affect case life or performance. On non-plated brass, you may also notice all the anneal stain might not be polished off, which may give the case neck a pinkish color. With some smaller caliber cases you may notice the case mouths to be slightly belled.
With all new rifle brass, you should first straighten out the case and case mouth, then chamfer and debur the case mouth inside and out. To straighten the case mouth, run the case part way into the sizer die and let the expander ball straighten the brass. To prevent the case neck from stretching, be sure to lubricate the case neck inside the case mouth.
