Re: Tubbs Final Finish in a Used Barrel
I use a Tubbs final final finish on all factory barrels, new or otherwise.
I don't use the full (all the bullets) but some of each. Goodgrouper and UncleB have posted regarding FF. I followed their posts and things have worked out very well.
Having said the above, I have no personal criteria pertaining when to use the final finish process. Copper fouling is a pretty fair indicator, though.
