Only one that's actually mine is an old (and by old, I mean it's over a century old) .22 rifle, inherited. Own it for that reason, on top of the potential selling opportunity if things got sketchy enough. Last I checked on it it's still in fairly good shape, and you can usually get a pretty decent price for an antique rifle, particularly if it's still in working condition.
Been a while since I used it, though. Last time I fired anything not air-propelled was a year or three back, for a concealed carry course whatsit. Opportunity's there, since while I only own the one there's like a dozen or three (mixed rifle, shotgun, and handgun of various makes) I have easy access to, on top of family that's aware of where the local ranges are if for whatever reason I wanted to mess around with something fancier. Just not really interested these days. Don't hunt, far too aware of the statistics when it comes to self-defense, most use I'm likely to have any time soon is possible snake killing or somethin', and that don't exactly need rust shook off to manage. Or much in the way of firepower really. Killed a few rattlers et al over the years just with a BB gun, heh. Target/skeet shooting's interesting enough, but it also involves outside and money, with the former being miserable in this goddamn swamp and the latter scarce enough at th'mo spending it on ammo is... kinda' stupid, if you're not going to hunt with it.
Fair bit more active with the things when I was younger, though. Still didn't hunt (most wild game tastes kinda' nasty to me for whatever reason, and pure sports hunting is an abomination), but more leisure shooting, occasional skeet et al outings, that sort of thing. Was a'ight. Appeal largely wore off at some point, but it's not a regret or somethin'. Probably get talked into going to a range at some point in the next few years, I'unno. Actually never shot at a proper firing range, now that I think about it. Bummed around an outside police range a bit and some of the stuff at the safety courses I've been to might have counted, plenty of shooting in the woods or clay/sand pits or whatev', but never a commercial range.
