Thank you for that seeing it written within the act would be beneficial however i am unable to find it below is section 28
the only reference i can see is via the appeal process, where am i going wrong ?

its also refers to shotguns only.

(b)is satisfied that the applicant does not have a good reason for possessing, purchasing or acquiring one.
(1B)For the purposes of paragraph (b) of subsection (1A) above an applicant shall, in particular, be regarded as having a good reason if the gun is intended to be used for sporting or competition purposes or for shooting vermin; and an application shall not be refused by virtue of that paragraph merely because the applicant intends neither to use the gun himself nor to lend it for anyone else to use.]
