Remington Reloading Brass 8x57mm Mauser (8mm Mauser)
Remington cartridge cases are carefully drawn from specially-alloyed brass to provide consistently exact internal volume and resistance to case stretching and brittleness. Primer pocket tolerances are held to .001", and closely monitored case neck annealing ensures easier re-sizing and longer reloading life. New, unprimed brass. This is not loaded ammunition. Bulk brass should be full-length sized, trimmed and chamfered before loading.
- Caliber: 8x57mm Mauser (8mm Mauser)
- Finish: Brass
- Due to the manufacturing process and/or shipping, case mouths may not be perfectly round. To ensure a round case mouth, cases must be sized (or have the expander ball of the sizing die run through case neck) and deburred/Chamfered prior to loading.
A light "staining" may be found on the case neck of new brass. This is due to annealing. Annealing is a process, performed by the manufacturer, which involves rapid heating to a specified temperature followed by rapid cooling. This process imparts cases with the proper hardness to securely hold a bullet as well as gives flexibility to expand and contract upon firing and repeated forming. The "staining" is a residue from this process. This stain may be removed by tumbling before loading.
What Mauser Ammo and Reloading Components do I need?
MidwayUSA carries JS and JRS 8x57mm (8mm Mauser) ammunition and brass. The standard 8x57mm JS Mauser is by far the most common version of this cartridge, used in military and sporting bolt action rifles. The less-common JRS Mauser is a rimmed cartridge developed for double barrel rifles. If you have a bolt action 8mm Mauser, you will want 8x57mm JS Mauser ammunition and components.
