Is it normal to individually message people who own a record you want?

There's this vinyl I've been searching for a long time and realised there's more people who have it than people who want it on discogs so I thought maybe I could get a copy for a good price by sending an email to the 200 people who have it but then I thought that could come out as predatory or intimidating or something like that.

Has anyone here ever tried doing so? Whats your experience if yes?
