If small propellant is kept for terminal phase then perhaps Pk can be increased. IDK if dual-pulse rocket motor ignites after locking the target in terminal phase. Astr-2 is dual-pulse but IDK if Ramjet missiles like Meteor & Astr-3 SFDR are mono or dual pulse.
It is the interest of dual pulse powder engine, or throttlable ramjet.
In the case of a 2 stages powder engine for exemple : the first stage burnt a few seconds, and give the missile energy to cross. Once this energy is lost due to potential energy loss (if it has to climb) or drag : or the missile fall, or it use the second stage. Once the 2nd stage energy is lost, the missile fall.
The max range is only reached in perfect conditions : missile fired from a high speed fighter, from the higher altitude possible, and against a 0G target in low altitude.
Once any of this condition is false, the range is lowered.
In the Meteor case :
Max range never disclosed, but some said >300 km (ie fired from a supersonic jet, at 15000+ meters height and against a static helo just above the ground)). In this case the missile with the less drag possible because flying main part of the trip at high altitude and no loss because manoeuvers use low amount of fuel/km.
NEZ is >60km (maybe 65, 80...) is the case of a jet flying low, in low speed, firing Meteor against a 9G fighter at 15000+ meters height. In this case the missile has to make some hard turns, and use max fuel to gain altitude.
