My access is restricted to what is available online, so this figure is on the lower side.
Lastly, they keep fine tuning it, so I was surprised when 120km range was announced, when earlier they had successfully carried out tests at 140km.
Just speculating, but this case of 120km seems to be way on the lower side, I was expecting 180/200km.
The range vs payload argument doesn't really apply here since, these rockets have limited space for warheads.
Nonetheless, something "good" seems to be at play here....
