I know a couple of Finns on a discord server. They seem like pretty friendly people to me. I dunno, maybe it helps to have some kind of common interest first? One way I've found to meet people--although not always people I want to meet--is to see what other people are bringing to the gun range, and then ask them about what they've got, assuming that it's something neat. That's how I got to try out a CZ Shadow 2 Compact (...and I'm now waiting for the one I ordered to arrive!), and got to talk to a cool RSO.
I think the Finns I know would be happy to talk about things like that, and would probably even let you shoot a magazine or so.
