Is this .223 Rem ammo new or remanufactured?
It is remanufactured. The cases are processed once-fired brass reloaded with new components, and the listing above spells out the exact brass type.

FMJ stands for full metal jacket: a lead core fully wrapped in a harder metal jacket. It does not expand like a hollow point, which keeps it cost-effective for practice.
