Yes, Tack it's from the latest version that all FLDs are instructed to be adhering to.
Dean, overseas use is perfectly acceptable as a good reason, but make sure you get UK deer and AOLQ included on the back of it. Copy of your Norge hunter's licence or letter from someone over there where you are shooting would be good supporting evidence if the FLD ask for sight of it.
BTW. there's also this section of the current HO Guidance relating to use of a rifle for deer that appears to negate their argument that you must nominate land if you can establish overseas use:
13.32 An applicant who wishes to shoot deer should name land which has the likelihood of the
appropriate deer species being present, and an invitation, booking or authority to shoot.
This is not necessary where a person already holds a deer legal rifle for an established
reason. Many deer stalkers will rely on invitations to shoot on payment rather than be hired
or paid to do so and may not be able to shoot regularly or frequently, though others may
be permanently employed, for example, Forestry Commission staff. Hunting large animals
with powerful rifles requires particular skill, and applicants should generally have some
experience of firearms.
As Tack says, have a good look at S.13 of the Guidance and be prepared to quote any relevant sections.
