I am on the fence about using this stuff. I have heard a lot of praise for it, but have also heard that it can junk up the your bore. so I thought I would through out a thread to weight the pros and cons of this stuff. I have a friend who shoots benchrest, and he swears by it. says you can shoot all day long without scrubbing the gun. I hear that doing this can lead to "moly rings" in the bore. he also says that it will extend the life of the barrel, due to less wear on the lands. there are also claims of improved accuracy with this stuff. I'm sot so sure that is true, or even how much of an improvement it makes. any thoughts are much appreciated! thanks guys!
