0.22 Calibre Nail Gun ammo still available?

[ubersonic]

Does anyone know if you can still buy 0.22 calibre singe shot nailgun ammo in the UK? I've tried looking on Google but it's all in the US or long out of stock. Are we even allowed these anymore of is this another nanny state issue? I wanted to do some DIY today but I've run out of ammo

Are they not just .22 blanks? I always assumed they were.

I could be wrong but I don't think regular blanks have enough power to drive nails into wood/metal/concrete. The nailgun rounds have velocity's of 100-400 m/s depending on grade.
