From This Slide It Looks like the circles represents 100 km so inner circle is 100 km, middle Circle is 200 km and outermost circle is 300 km (the text mentioning it is blurry but still visible if you look hard enough) and 0 degree indicates tail chase mode, 180 degree indicates Head on engagement mode
SO based on that info here are my guesstimates
PL-15's head on Engagement Range is around 180km and tail chase Range is 90-100km which is quite Good (Again its the PL-15 not PL-15E)
The New PL-16 may have 260Km range in Head on engagement and 130-140km range in tail chase Mode.
PL 12's head on Engagement Range is around 70km (Again its the older PL-12 not the modernized PL-12AE)
