2500 km is a realistic range of you follow the war in Ukraine. Kyiv is frequently attacked with Shahed drones and it is far from frontlines.
Kyiv is pretty close to the Russian border to its north, even Moscow itself is less than 1000km away.
I think the furthest hits Ukraine has been able to achieve with drones were on a refinery about 1300km from Ukraine controlled land.

It's a couple of hundred miles from the frontlines in Kharkiv, and the Russian border to the North is even closer.
