    It’s not painted as a casing, more like an exceptionally extended body. It rather looks like a tracer projectile body. I suspect somebody searched for 5.56mm projectile references and picked the tracer at random.

    The crimp mark is quite far up though, rather than on the major diameter.

      It is quite clearly painted as a brass casing, the rear half doesn’t look close to the same color as the front copper in the op.
