Yes I've had a "prop" strike. Airplane was in the hangar, no prop wings or tail feathers, inadvertantly dump it on the nose, i.e. engine flange, took a small divit out of the concrete floor. I went through all of the senarios posted above, had a conversation with my A&P, the result, I called my insurance company, prop strike inspection was covered, insurance paid the bill. No damage found from the "prop" strike.

My advice, if you have hull insurance coverage, call your agent.
