Anybody used the Tubb Final Finish Bore Polishing System? I have read a couple of reviews on it and was thinking about using it to break in my new barrel but wondered if someone had used it and what results they had.
I did and it destroyed a factory barrel. Viewed it with a hawkeye borescope before and after, and it rounded off the rifling. It was smoother. Gun went from a solid 0.5-1MOA gun to a 1.5-2MOA gun. It was just so rough and hard to clean before.
I still have set of the bullets if want to buy.
