Need to tap into some experience on barrel FinalFinish TMS...

[Cimarron2011]

Has anyone on here used David Tubb's Final Finish TMS system? They claim to improve accuracy and extend barrel life. Can anyone support or deny those claims?

I would change your heading to has anyone used tubbs final finish.It will attract more responses.

I used them on one barrel that was accurate but had some tooling marks & fouled pretty easily. I only ran the 3 finest grits which I THINK from memory are 800-1000-1200 grit. 5 shots each with complete cleaning before & after each string. It definitely made the barrel easier to clean and it also picked up a slight improvement in accuracy. I have heard that fire lapping in this fashion creates a tapered bore BUT I certainly don't have the equipment to measure it. I wouldn't hesitate to use it again but haven't because I started buying lapped barrels. That barrel last year doing an impact check at 300 yds before a hunting trip put 5 bullets into a .202 group with ballistic tips so I wouldn't be concerned about hurting accuracy. One of my best shooting barrels.

Correction, pulled out my Tubbs kit & they are marked #1-#5, with no grit rating BUT they are definitely not finer than 400. I used #3-#5 as per their instructions for good shooting barrels.

Yes, I have use both the final finish kit and the TMS (throat maintenance system) kit. The final finish was in a rougher barrel which fouled more then others. I occasionally run one or two TMS bullets though after a major clean, but I don't know if it is doing anything as the expected results would be hard to judge.
Now that I don't have any guns still running factory barrels and can't for see any in the future, I don't think I will be needing to use the rest of the final finish bullets, but if I was to get another hunting rifle with a rough factory barrel, I would certainly try the final finish kit again.

Thanks for the advice Jon.

Larry, that is good info. Sounds like the barrel that I am working with is in about the same condition as the one that you had your experience with.

What caliber, as I have some bullets left.
