I've got an air rifle, though can't remember last time I fired it as its a pain in the arse digging a backboard out the garage to shoot at.
I've fired .22 rifle, MP5, SA80 (both the fully auto and cadet versions), and some sort of 9mm pistol and its quite fun, but I'm not sure I'd be bothered about owning one.
It would be nice if there was more opportunity to go somewhere and have a go at shooting in the UK, but I imagine it's be a stupid price.
