hetzer88,
I have actually used the ultra bore treatment. had a custom 30-06 treated by 'Fit4Duty' 5 yrs. ago, at that time it was called 'micro-slick'. it's a hunting rifle, & I shoot Barnes 165gr. TSX's in it. It definitely cleans up better than before treatment.
I did three other of my varmint rifles, 223, 22-250, & 6mm. after 200 to 400 rds in each of them, can't tell any decrease in accuracy, but my rifles are varmint, & hunting, not BR.
don't know about the comments from the other posters, have they actually used the bore coat, but my rifles, really cleans up fast, even after I run 30 to 60 rds. down the barrel. use some wipe out, & a few patches, & it's clean.
I'm not a 'tech' person', so the comments from the other posters may be right.
just know my barrels clean up a lot better than they did before I treated them, but as I said, mine are hunting, & varmint rifles.
my take on a lot of things like this are ' opinions are like 'butt holes', every one has one.
