Hi All, did some browsing over the weekend and found some decent websites re airguns.
This is the main page, see specifically the link;
for 2 pdf downloadable airgun magazines. they seem fairly nice with articles and reviews, I have not gone through these.
There is also a link on the main page to a local Eastern Cape outfit that caters for big bore airgun hunting.
The Americans seem to be quite into their large calibre airgunning.
