I will chime in with my experience for what it is worth. I have used Tubb’s FF on 3 factory Remington barrels. I first broke them in as best as i could in order to get the best possible improvement with the FF bullets. I only used 5 of each grit and thoroughly cleaned between each 5. The result in each barrel was a bore you could feel the smoothness difference. They all cleaned up much easier. The 223 barrel shot awesome. I pulled the barrel at 3000 rounds still shooting 1/2 to 3/4 MOA gropus.
The 308 and 30-06 barrels did better but were still just MOA or slightly better. What was different was that the grouos were now round and the cold bore shoot was much closer to the 5th shoot from a cold clean.
I have sort of a testimony about what it can do with a well used barrel. I bought a service rifle pulled barrel from one of the juniours guns at about 3k rounds. I took it home and it took seversl days to get all the copper out of it. I then decided to do a FF on it because it was clearly long inthe tooth. Again i just used 5 of each grit. The results were that it came in as a 3/4 MOA barrel and cleaned up easy. I shoot that barrel for another 2k rounds as my NRA match rifle. It became the first barrel that I literally shot it to death.
Based on what i found out about FF I became a TMS user. I use them at the beginning of the range trip were i have 200 or so rounds down the barrel. I do them first rather than last so that the bare steel sees the polishing first. I cannot tell that life has been effected adversely.
