Unlike the USGI ammo, which has non-corrosive Boxer primers, it has corrosive Berdan primers. The cases have longitudinal scratches along the sides, like they have been reloaded. The bullet has a black sealant at its base and the primer has a clear pinkish-red sealant rather than an opaque red sealant. They come packed in 50-round cartons.
