Robust Luger action? High ejection?

Shot a few times , very nice , impeccable action, ejection. Could not find all the shells??? WTH!?

I shot again and looked up following the ejected cases...Jesus they flew like 25 or more feet in the air, and apparently some rained down on my roof, stuck in the gutter.

Is it normal Luger operation? Safe for the parts or it indicates too powerful ammo?

NO, that is not normal... not even close to normal. While the ejection pattern of individual Lugers may vary somewhat, the case should end up 6 or 8 feet away in most instances.

I suspect that your recoil spring is much too light. It's possible that a previous owner clipped coils from it.

Wolff Gunsprings sell Luger recoil springs in several weights from reduced power to extra-power. They even have a pack with multiple weights. They're good people to deal with.
