By "ballistic reticle," are you referring to a "BDC" type drop compensator, or are you talking about graduated reticles?
If general graduated reticles, not trajectory matched, non-uniform BDC types, then Sig's Tango line are FFP with milling reticles. I just picked up a Sig Tango4 4-16x44mm mil/mil. Haven't had time to mount it yet, but will be very soon.
