Belom ammunition is manufactured in Serbia to the highest Mil-Spec standards. They begin each round with a virgin brass casing capped with a boxer primer making this fully modern cartridge ideal for not only your first shot but also great for reloading. Both the powder and primer are 100% non-corrosive and the cartridges are certified as waterproof to provide a long storage life and sure-fire ignition. The 123-grain bullets are lead core and an antimony alloy for stabilization and a true copper jacket so they are non-magnetic making them approved for most ranges. From a personal standpoint, even if I am using steel-cased ammo for my primary blasting go to, I like to keep at least a certain amount of high-quality brass-cased ammo on hand and there is no better choice than this
