I do see in this posting that Hoppes 9 BR is stated to have changed over the years, and I last bought a large bottle probably 5-8 years ago. Don't know what that tells anyone.
The Bore Tech stuff impressed me well enough (again using a bore scope) that I pretty much switched over to that brand.
Their copper cleaner also states that it is reccomended to leave a light coating in as a sort term corrosion preventative.
While I don't usually do that, because I follow everything w/ dry patches and then Eezox, since the Bore Tech Cu+2 can be used that way I have no quibbles about letting it sit in the bore longer than the reccomended 10 or so minutes if I am multi-tasking. I don't do that with the amonia based copper removers, as I have been advised that they can etch the bore if left for too long.
I don't fear JB bore paste either, though I only really use it infrequently when something (lead, copper, fouling from plated steel jackets, or whatever) just won't budge.
It has never let me down, and whether it was that or just shooting it several hundred rounds, my significantly pitted/frosted M99G that was neglected does seem to also now clean quicker after some polishing time w/ JB. I did spend about an hour on it one day w/ stroke after stroke through the bore with JB.
(I also used it on the chamber to ease the pitting after the scotchbrite followed by 600 grit paste -- the cases wouldn't extract at anything over a 80% of maximum load when I first got the gun, and now it does give me reasonable velocities w/ easy extraction. Maybe the JB didn't do much there, but figured as a final pit easing / polishing step it couldn't hurt.)
Anyone on here use Balistol?
I got a large can of that in some estate sale find, and now I am curious where it will work best.
