Much of the cheap milsurp ammo is "Corrosive". This does not mean that there is anything in the amnmo that is like an acid, attacking the metal.
What it measn is that the primer compound generates a salt deposit in the barrel and gas system. Salt, by it self is not a problem. But salt attracts water, and then steel rusts quickly.
The big variable is water vapour. In a dry winter house, leaving the rifle for a few days would not be a problem. In a well humidified house, or in the summer, the rusting process could start almost immediately.
It would be best to strip the rifle when you get home and wipe it down. I find that if I strip it, put a wet patch through it and then go and get a beer, the rifle is ready for a final wipe and oil by the time the beer is gone.
In the summer time it is easy to take a bottle of water to the range (say a one or 2 litre pop or waterbottle) and to pour it down the barrel from the chamber end before putting the rifle in the car. This water will wash away 99% of the barrel salt. But you still have to clean the gas system when you get home.
I like salted peanuts and butter, but prefer my ammo "unsalted", if possible.
