Devon & Cornwall Constabulary, always one of the most switched on and sensible when it comes to firearms matters, have now apparently decided to allow all (major species) deer legal calibres to be conditioned for boar.
Extract from the minutes of the last Firearms Liaison Committee meeting:
"The meeting was advised that DEFRA‟s recommendation was for .270 to be used on Wild Boar. This was to have been raised at the National Conference, which has now been cancelled. However the meeting was advised that applicants should apply for cover on all lawful animals and should ask for .243 for Wild Boar. If an applicant has a calibre for deer it is in order for them to use it on Wild Boar but if applying for Wild Boar only the reason will be assessed."
