Borrowed from a different forum and the poster was Nimrodder. Very interesting read.
Personally for many years I used Sheath aka Barricade. I also used Breakfree CLP. Rem Oil was my short term stand by oil (right on the shelf and easy to reach). Now I have been using the Montana X-treme Gun Oil and that seems to work real well. But remember, my rifles are technically never stored. I shoot them all from time to time.
