I mean if you just want something for hunting or plinking, I feel like any classic bolt action rifle would probably be fine, no? The reasoning being that it’s a relatively low risk gun generally, if someone else decides to steal it, compared to like, a tricked out ar-15, and it’s also much cheaper than that, as well. Depending on what you’re wanting to hunt, you could have an air gun, or a much smaller caliber, as well, and improve the cost and relative safety. If you’re looking for hiding and hunting guns, then something that you can take down might be a good call, and then you could store the two halves in different places.

I dunno, I’m assuming you’re wanting to hide your guns from people who might steal them, rather than like, your kids, or friends, or some sort of accidental discharge situation, cause if that was the case, I would probably just recommend one of those trigger locks that everyone tends to poo-poo on, which would pretty easily prevent any accidental idiocy as far as other people are concerned, but not not prevent a committed criminal from breaking through it, and they might steal it pretty easily as well. I guess it doesn’t matter what you end up getting as much, but if you’re really concerned, you could put a bike lock through the magwell, and out of the chamber, and then through some harder piece of your car, so nobody can get it out unless they’re bringing a hacksaw, or unless they’re a great lockpick. I would recommend anything you might get with a tubular lock, those are pretty hard to open, kind of overkill.
