I oil stored guns (that haven't been handled) every 6 months. I wipe down guns that are handled with a silicone treated cloth and oil them before putting them away. I have a Savage Stevens Favorite (#453 made in 1894) that I inherited in 1979 that is still rust free.
"If someone has a gun and is trying to kill you, it would be reasonable to shoot back with your own gun." The Dalai Llama (5/15/01, The Seattle Times)
"That rifle on the wall of the labourer's cottage or working class flat is the symbol of democracy. It is our job to see that it stays there." George Orwell
