"Don't close an unclocked bolt on a live round in the chamber. The firing pin will rest on the primer. ???

Is this true? Don't primers rebound! They're not loose sliding around and even protruding resting on a primer. Or are they? Any particular rifles at fault. "

I never do this with a bolt action, Mauser-type rifles, due to the hard pressure of the pin against the primer. Dropping the gun "could" cause a discharge.

SxS's with rebounding hammers do not share this event.

On bolt rifles, I always store them uncocked, with the pin sticking out of the bolt.
