Not in properly designed/manufactured rimfires.  There's no need for the
firing pin to strike the breech face.  It can stop short by at least .015-in.
and the rimfire cartridge will still fire very reliably.

Only in ones not made correctly.

Shotguns, especially doubles and singles; their firing pin/hammer design
coupled with their softer receiver metal can be easily damaged by dry
firing.  Shotshell snap caps are virtually mandated for break action
shotguns; pumps and semiautos may be different.

I and thousands of others have been dry firing a given rifle hundreds
of times a year.  This is the same action and firing pin that's been
used for 20 to 30 years.  No metal fatigue has set in at all.  And
many of these firing pins are driven by springs having more force
than standard factory springs.  These are centerfire rifles, such as
Win. M70s and Rem. M700s.
