Re: Tubbs final finish :-(
I've used a Tubb Final Finish kit on two rifles over the past couple of years. A Savage 99 in .308 Win, I only used factory ammo in. The rifle went from a 1 1/2+ MOA off a sand bag to a minute at 100 yds.
The second rifle was a new Remington 700 in .223. After breaking it in, I developed a load that would shoot about 3/4 MOA but I couldn't get it any better. Curiosity finally got me and I fire lapped the barrel using only the 3 finest grit bullet sets in the kit. I did have to re-work the original load a bit. Powder increased very slightly and the 52 gn Sierra MK is seated closer to the lands. The gun will now shoot under 1/2MOA and often better when I do my part.
Would I use it again? Yes, in the right situation such as a factory barrel I want to shoot better. You would, however, have to twist my arm hard to get me to put it through any of my match grade barrels. Maybe when I get one that starts to lose accuracy I'll try it.
This was my experience with the product. Hope it helps.
