Norma Brass provides the serious reloader a premium grade, quality cartridge to reload. Norma Brass is bulk packed from the same lot. We try to keep a good supply of brass in inventory, but due to factory production and delivery delays, we may occasionally be out of some cartridges. Norma Brass is made to such exact standards that the cartridges typically include machined case heads, drilled (not punched) flash holes and close tolerance wall thickness. Brass is packaged in 100 count bags.
