Thanks guys.
I'm in Stavanger, so hoping to find a range close to there that i can join so i can get going.
Emailed the contact address at Øksnevad / Klepp, so will see what they say when they reply. Do the local clubs have sport shooting year round, or do they stop during the winters?
We don't have a legally required hunting certificate in the UK, so i think i'll need to take the Norwegian test, but that's fine, i'm more than willing to sit the exam. Might learn something along the way.
