Thoughts on Tubbs Final Finish?

I acquired another new M1A this past weekend along with a new Howa Mini Action rifle.

Listening to a Camp Perry shooter that some of you may know, he kept mentioning "You need to try out Tubbs Final Finish on those barrels before you really go to loading for them and shooting them!" .

I cleaned the M1A and the barrel finish is quite dull, and so is the Howa Mini Action. Would running Tubbs Final Finish loads through either of these rifles have any drawbacks that you can think of?

My only concern is ... does it prematurely wear the barrel or throat at all?

Thanks for the input.

Question

This is a exaggeration but let me put it too you this way... Would you wax your car with sandpaper?

Absolutely not.

Is there a less aggressive way to polish the bore?

No but I would polish it with different steps of rubbing compound.

Thanks from 1100 tac

I used these in my AR and my M14 when breaking in the barrels. I have great accuracy in both but then again they are both NM rifles. These were recommended to me by a retired secret service agent who did a brief stint as a sniper on the protective detail. That recommendation was enough for me. YMMV

I don't know my base line, because I used Tubb's on my new M1A Scout before firing. The rifle shoots better than 2 MOA and the bore is very slick, and easy to clean.

Final finish works, the question is how much good it does on a run of the mill service rifle or bolt gun?

I have not used the Tubbs system but know many who have. If the new barrel is showing signs of heavy copper in the bore, obvious rough spots by eyeballing it, etc., some sort of polishing/burnishing the bore is in order. Most quality barrels today are pretty much good to go and in cases where excessive copper have used JB Compound which is a very mild abrasive compound/grease that will polish the bore. Only use it for the first 1/3rd of the bore and avoid the muzzle portion. The copper is picked up in the bore when bullet first leaves the chamber and continual firing will tend to spread it toward the muzzle. If you smooth out the bore at the breech end, no more copper migrating forward. For those barrels showing copper residue I have found using JB will reduce or eliminate that in short order. Remington offers a product known as RemClean which looks like mud but will polish the bore fine and CemiChrome is a paste used for polishing engine parts, motorcycle engine cases, etc. and is similar to what is called jewelers rouge. None of the above items cost as much as the Tubbs system and they are not as aggressive in their application. Just a suggestion.

Thanks from ConRich and boomerpusher

Final finish and other abrasive products may void the barrel warranty. Better check that before using it. I would not use it on a quality match grade barrel as it just is not necessary but, it can certainly smooth out some of the lesser quality barrels. There may be a slight reduction in velocity after using final finish. A friend of mine documented his results before and after use and noticed that his velocity dropped 50 fps in his AR using the same load. Your results may vary. Disclaimer; I have never personally used final finish.

I don't know if it was effective, as I shot them first. I can tell you they are really underpowered and you might have to cycle them manually

For the record ... the M1A that I purchased was another Scout Squad. I assume that it has a standard grade barrel on it.

The way I understood the purpose of the Tubbs Final Finish system was to either renew a heavily shot out barrel or to burnish a match grade barrel for that extra little bit of accuracy. On the one hand, you were possibly saving a shot out (accuracy wise) barrel and on the other hand it was worth the possible extra wear on the barrel, because supreme accuracy was the goal, not longevity. For a scout rifle that isn't seeing competition, I don't see how the wear on your barrel is worth the relatively small gain in accuracy.

As the process makes the barrel smoother, that would reduce wear. If a hand lapped barrel is good, why is a fire lapped barrel bad, as hand lapping also causes "wear"? Not trying to be smart, but trying to get smarter by asking questions.

If I had a near shot out barrel, I suspect Tubbs might help a bit. My understanding is that people mostly like it because its makes copper cleaning much easier, especially if the barrel is a little rough. Thing is, foaming bore cleaners, especially Wipe-Out, will clean all that copper out (and everything else, you should see some of the crap it pulled out of CMP rifles I've ordered in the past) in short order, and save you a whole lot of elbow grease and patches in the process. No abrasiveness, no bad odor.

My thought is, if a barrel shoots well, leave it alone and let the chemicals do the cleaning. I like tinkering with stuff as much as the next guy, but I try not to fix things that aren't broken...it usually results in me having to fix something that wasn't broken before I "fixed" it.

I have done this to several rifles, including high dollar target rifles, with nothing but positive results.
It does more than just polish. I think the dimensional uniforming results are more important and the smoothing is just icing on the cake.
I would not use it on a barrel that is already shooting well, so I wouldn't recommend doing it to a new rifle without giving the factory barrel a chance.
