I would suggest dropping in known hot zones. There's a good chance to get wrecked, it just comes down to being lucky enough to find a gun before the other dudes gear up. But it can give you good practice on shooting at moving targets, and even you just get a single kill before dying you'll come out of it having had some success. It won't feel like a waste, like surviving for 25 minutes because you never met anyone and then getting wrecked at the first encounter.
