Welcome to HuntChat Carolin. Sorry I can't help you out for the countries you're interested in. I know some sites in Poland and Czech, but they are for hunting and not magazines. I'm guessing by your title you already know the ones in Germany !!
But, Skyline, if you're interested in German Hunting Magazine sites, I can help you out there. I've also put a link to the Deutsche Jagd Verband with a lot of information. Alle auf Deutsch:
