I suspect it is inadvisable, but I've read of some firing 22lr from 22wmr break and bolt actions, despite the smaller case. Some report increasing the 22lr case diameter, for instance with a bit of electrical tape, some leave it as is. I would expect this would result in some split cases and greater bullet instability because of shorter oal. But would it do any damage to the rifle?
What about with larger rimmed calibers? For instance, it looks to me (from the specs) like a 30-30 round could chamber in a .303, maybe even a Mosin. What about damage then, with the higher pressure? I know accuracy would probably be even worse than the 22lr in 22wmr because of the difference in bullet diameter. And cases would be ugly. But what about the rifle?
I don't have a .303 so don't worry, and wouldn't try it anyway. And where I am, 22wmr is easier to come by than 22lr and close enough in price, so there isn't really a reason. I also know there are chamber conversions, but I think they require blue loctite and heating in order to return to the primary cartridge.
Chalk the question up to apocalyptic fantasies about useful survival rifles.
