45 70 Brass (Large Rifle primer) 2.095″-2.102″ O.A.L.
Ammo Marsh .45 70 brass 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.
