What can one use to shoot hares in Ireland?

I recently got told on boards.ie that it was illegal in Ireland to shoot hares with a rifle. I had a browse round the Irish Statute Book and found this:

(3) It shall be an offence for a person to hunt or injure in the course of hunting with a shotgun a protected wild animal other than a hare otherwise than under and in accordance with a licence granted in that behalf by the Minister.

Now this seems to say that it is legal to shoot hares with a shotgun, but not that it is illegal to shoot hares with rifles. I have asked in the forum and got told to ask my local ranger or the Ministry for the Environment. I have asked a ranger who is on boards.ie via private message and I rang the ministry who took my details and promised to find out and ring back. The guy actually sounded interested. My current impression is that this may well be a well perpetuated myth.

I am admittedly finding it bizarre enough that one cannot hunt protected wild birds with bullets in this country (doesn't apply for vermin such as crows as far as I can see) and would be surprised if one could not hunt the smallest protected mammal with a bullet - on earth why? But we will see ...
