After shooting, especially in hot weather, I first wipe the gun down with a damp (not wet) rag or paper towel in order to remove any sweat, which contains salt. Salt, of course, is very conducive to rust. Then I wipe with a light oil to prevent rust.
A damp wipe won't leave much moisture, and it will evaporate right away.
Ditto to what Redneck said about hot ammo. Cooking .22 ammo seems to do something to the lube, and it can mess up accuracy. I live in the desert, and am very careful about that. In hot weather I carry my ammo to the range in a large baggie, in my cooler.
