RE: What is a CRUD-RING
I used a lot of different oils. I went through a WD40 phase and that stuff worked real good. Then I got hooked on Rem Oil for a long time. Then a couple years back a poster told me about Birchwood Casey Sheath and I started using that. That has to be my all time favorite. BUT I keep Sheath, Rem Oil, Breakfree CLP, and Kroll Oil, Smith & Wesson bore treatment, and WD 40. I also got the Montana X-treme because of Sabotloader. So I like to try a lot of different things. Some rifles are protected with one thing and some with others. I guess that the advantage of have a few dozen rifles to play with.
