German Military Surplus 308 Winchester Ammo 148 Grain Full Metal Jacket ammo review offers the following information; This 308 Win ammunition was originally made for the German military by Chemnitzer Sportwaffen und Munitionsfabrik GmbH, but has been repackaged for international commercial sale. These cartridges sport 148 grain full metal jacket projectiles, which are a lighter weight for their caliber. They take their distinctive color from the cupronickel that their jackets are made of, and they are magnetic because of the iron said alloy is strengthened with. These rounds’ low price tag and ability to prevent rapid bore fouling make them an exceptional choice for high volume shooting. These rounds offer brass casings, although they’re not a great medium for handloading given their Berdan primers. Still, that the primers fitted into these likely 90s-era milsurp rounds’ casings are non-corrosive means that you can confidently invest in them.
