I have not read all the posts in this thread... so if I walk something I am sorry - did not do it on purpose....
I do remember reading some where that you might have some concern about plastic fouling in the bore. With the older formulation of sabots, this is/was a possibilty. Looking down the bore and seeing how bright it might be is not an indication of a clean bore. There is probably fouling, especially plastic fouling caught on the leading edge of a land, powder fouling especially can easily be had with water and a bore mop as the powder is fouling is water soluble, while pastic residue is not. The newer sabots that are available today using a new formulation of polymere does not present the problem that the older formulation did.
The '
TOOL', I can not really speak for it or again it as I have never used one. I have seen them before and looked at the adds but realy never felt it was a advantageous to me.
If you really want to rid the bore of any fouling and especially plastic fouling then I would suggest it needs to be stripped back to bare metal. One method is using JB's bore paste it will do a very good job but it is possible to still leave some plastic fouling in the bore.
Here is a video explaining the JB method:

If you really want to get everything out of the a ML bore I think the best method continues to be to flush the bore with clean boiling water and then while hot use a bronze brush to brush out the loosened materials.
If you do this and you have a blued barrel, dry the bore as quiclky as possible - I blow compressed air through and then dry patches. You still may get a bit of flash surface rust.
If you have a stainless bore you will not have to dry as fast and you probably will not experiance flash rust.
The boiling water expands the the metal in the bore flushes the pores of the bore, cause lead or copper fouling to flake and softens the plastic residue to the point it will not adhere to the metal.
On a gun that I shoot a lot, I will do this procedure a couple of times a year. Others may not get this treatment only o very few occasions. All that I am having accuracy issues with will get this treatment after I have eliminated stock to brrel issues and sight/scope issues.
Just another thought if you are using a bore oil with teflon in it, or a petroleum based bore oil, you might consider switching to a synthetic oil.
Hope some of this might help...
