I remember a story I heard years ago, when Appleseed was a fairly new program.
A guy in Wisconsin (I think it was Wisconsin) went to an Appleseed and shot a high enough score to get his Rifleman's badge. When they asked him how long he'd been shooting he told them he'd bought the rifle and done a lot of dry firing with it, since he really didn't have a place to go shoot. He just practiced the fundamentals (got from reading a pamphlet that that RWVA used to sell/include with orders for targets).
If you've never been to an Appleseed, I can tell you the average percentage of attendees actually shooting a high enough score to get that badge is around 15 to 20%. Shooting a rifle, even a .22 rim fire, at those tiny targets (even at only 25 meters) along with the magazine changes, the position changes, etc. ain't as easy as so many people think it is.
Anyway, dry firing, when done correctly, is very beneficial, even for experienced shooters.
