calibre

Once again I'm looking to learn from the collective wisdom of SD members, please help? I have been looking at the 6.5x55 SWE as an all round calibre (will probably only ever have one stalking rifle) and know this is a bit of a hot potato on SD forum and it is often a lively debate that follows...

Does anyby from Northern Ireland know if it is possible to get a deer caliber rifle passed for foxing in Northern Ireland? I have a 6.5x55 Swede and would like to use this rifle for foxes. Thanks Colin
