I have a club map that is based off the Shooting the breeze club map. I have currently 231 uk clubs listed as well a few others around the world. I'll check the map when I'm not on the mobile to see if I can add any to the list or even add clubs that I don't have for Scotland. I had hoped with the new license there would have been more new clubs formed to keep these that don't have land to shoot upon would have driven the need for new clubs.
I'll not post a link to my map as I am unsure whether there are rules to be followed on that point as I am not a frequent visitor to the forum.

I found this that has a few clubs that also cater for us Airgunners in one form or another.
