There is no absolute range for any missile, it totally depends on your target, their maneuverability, speed, directions and more importantly their electronic warfare system.
If your target is running away at March 2.5, range decrease.
If your target is running toward you at March 2.5, range increase.
If your target is P-8, or C-17, or KC-10, KC-46, range increase.
If your target is Boeing E-3 Sentry, range decrease.
So any figure on PL-15 range is misleading at least, it varies as many other systems as well, such as S-300, HQ-9, etc.
