Tubbs Final Finish bullets

Oddly enough I was just reading a blurb from Otis Technology about "Lifeliner", which they say is a ceramic barrel liner and is easily applied. They claim prolongation of barrel life to "...virtually indefinitely..."; large accuracy increases and muzzle velocity increases between 10 and 33 % depending on barrel usage. So, the topic is timely. Simple answer is that I don't know what to think about such claims. Any decent match grade barrel I've had has been very good and it is hard to see much room for improvement. It would be nice to increase barrel life or make a good barrel into a hummer, but experience over the years has taught me that introducing a new variable into anything can either improve things, make them get worse or leave things pretty much the same. Sadly there is usually a certain percentage for each of these results :(, providing one makes the effort to measure carefully. The claims are reminiscent of those made for molycoating bullets, most of which I haven't been able to duplicate. Then again, how many of us really have the time and resources to actually test these claims in any meaningful way. :confused: fred
 
There was an article I'd read by a guy names Bill Johnson in the states about the most cost effective ways of making a rifle more accurate. He had some pretty good things to say about the Tubbs system - I'd personally like to give 'em a try myself.

It's an article on the internet though, so just take it for what it's worth.

I was thinking about trying them on one of my match barrels that was pooched. In the end I didn't figure it was worth the time and effort into try and revive a lousy barrel, so I put a new barrel on.
 
I actually bought the final finish system recently to put through my 700P in .308. Now all I have to do is get home to actually do it. Once I have completed the process I will post both the before and after so you can decide for yourself if it's worth it or not. You're looking at over a month though, so you'll have to be patient.
 
and how long is a warranty.. my savage was one year and that was years ago. Chrysler told me the same thing about my truck.. yet if it could be made better and thus last longer it was all good to me...
 
After viewing the Otis Technology blerb and David Tubb's Final Finish, I have come away unimpressed, particularly pertaining to the claims of increased barrel life. Barrel life is subject to the flame temperature of the burning propellant, which occurs under great pressure at the throat of the barrel, combined with the rate of fire of subsequent rounds. Passage of the bullet is of lesser concern. I can see how a slippery finish might produce more uniform muzzle velocities, and reduce jacket fouling, which is why I use Microlon, but I fail to see how a claim of improved barrel life could stand up to scrutiny.

These products might be attractive to those who shoot with factory barrels, but I don't see how there can be of much benefit by the use of these products to the shooters who have chosen to invest in top quality match rifle barrels.
 
I agree the anecdotes are impressive, but until the results are quantified by studies under properly controlled conditions, the remain merely anecdotes.

There are pens you can sniff that guarantee weight loss, there are pills guaranteed to make your willy bigger, and schemes to make you independently wealthy by working from home....
 
Speaking from experience I had good results with both my .308 and my AR.Groups in both shrank.The AR showed the best results probably because it wasn't a precision instrument to begin with.My .308's groups got a little smaller on average,but going from .75 to .50 average is still decent.
A big plus for me was the ease of cleaning.Both hardly take any patches and very little copper comes out.
