Re: Tubb's final finish ?? anyone use it ?
I have used it on two rifles, both have factory barrels. One is a M-700 in 30-06 and the other is a M-70 in 270 WSM. Before using the system, the barrels were pretty rough. They now clean up like custom barrels. I used the 25 round method on the second barrel, 50 on the first. I believe they initially had a 50 round method but changed the process several years after it hit the market. I hand load all of my hunting ammo and accuracy is pretty good. Dont have any data to compare with factory rounds as far as accuracy before and after. The throat moved only .001-.002. I don't think I would use it on a custom barrel but on a rough factory barrel I would use it again.
