Been shooting shotgun for the last 15 years or so 22lr and 17hmr for the last 3 or so years. I live in Canterbury in kent I go up to Scotland vermin shooting every year and deer stalking is available. While I have been shooting for quite some time I have never been stalking and am looking for advise and help. My feo has advised that prior to granting .243 or .308 I will require my dsc1 I can understand the requirement and am more than happy to do it but need some basic knowledge before I sign up for this. Any help and advise would be greatly received.
