It has worked very well for me. I recently bought a M700VS in 308 & of course the bore is rough & is a copper factory. The M700 rifle, esp. in the Sendero "type" platform is one of my
favorite factory rifles & it may be the luck of the draw for me, but they seem to foul alot even when they are shooters. In my mind FF is just part of the purchase with these rifles.
You will not make peace with the Blue Coats, you are free to go.
