David Tubbs Final Finish and TMS Bore Lapping System
By: TexanTiger Date: September 23, 2012, 4:47 pm
---------------------------------------------------------
This one is long, bear with me.
My old 270 Remington 700 "Classic" is getting a tad long in the
tooth. Tight 1" groups have started to slip, and I have decided
that it's time to "project" my favorite deer rifle in the hunt
for a sub-MOA rifle. There are many things that can be done to
increase accuracy in a factory rifle, and some of them will cost
you some big bucks.
With budget in mind, 2 things are happening at the moment.
First, I'm re-tuning the trigger, bring it down to a crisp 2.5
lbs, and removing some of the travel. This is a pre- X-mark
trigger, so it has to be done the old fashioned way. Progress
with that, if there's any interest, will follow in another post
elsewhere. Lightening the trigger will decrease the amount of
pressure that has to be used to squeeze the trigger, reducing
how much movement I can impart on the rifle during the squeeze.
I may also refinish the stock, but that's strictly cosmetic and
another project for another time.
The second item on the agenda, and the subject of this review,
are David Tubbs Final Finish and Throat Maintenance System. The
two systems together are a series of 50 or 40
projectiles(depending on which route you go) coated in rough
aluminum oxide in progressively finer grits, starting with 10
very coarse grit projectiles, and ending with 10 very fine grit
projectiles (or 10 factory loads if you opt for the 40 round
kit.) Like shooting sandpaper down the barrel, the kit claims to
work by removing .00003" from the inside of the barrel. The idea
here is to smooth out any imperfections in the barrel caused by
tools used to bore and rifle the barrel at the factory, and to
smooth and polish the bore to a mirror shine through a process
known as lapping (this specific process, because its done by
firing rounds through the barrel, is called "fire lapping"). A
smooth, imperfection free barrel results in projectiles being
better stabilized when exiting the barrel and higher velocities,
both of which make a rifle shoot flatter, farther, and more
accurately. The system is touted to shrink group size, in some
cases by upwards of 300%. It also claims to make the barrel far
easier to clean and to reduce copper fouling. Hand lapping,
traditionally performed by gunsmiths and by high end rifle
manufacturers, is a time proven butvery time consuming and
extremely expensive proposition. This kit claims to provide like
results in a single afternoon at the range, and for only $35 per
20 round preloaded kit ($90 for both kits together with express
shipping) or $35 for the 50 rounds kit (but you must provide
your own brass, powder, and primers for the 50 round kit), I
figured it was worth a shot.
A little side note here, ALL factory barrels will have some tool
and chatter marks in them. Some manufacturers perform a process
called "hand lapping" on their production rifles. You tend to
find that only on high end rifles and custom made barrels
though, Sako, Hart, Liljen and the like, which of course adds an
extra step and raises the price. Even so, fire lapping can
improve shooting in those rifles, but you likely won't see as
much improvement as one would with a mass produced rifle that
hasn't been lapped, such as a Winchester, Remington, Ruger,
Marlin, Savage, etc. There are claims all over the internet that
3" groups became sub-1" groups after using the system.
The system is offered in pretty much all of the major (popular)
high power rifle caliber (and even handgun calibers) from .22
all the way up to .308. You have 2 options, either the 50 round
kit which comes with 10 rounds each of grit from #1(coarse) to
#5 (extra fine) and includes only the projectile, which you must
then handload onto your own brass and primers. For folks like
me, who haven't started reloading, this isn't the best option.
The second option is buying the loaded kits, which are 20
rounds, 10 each of 2 different grits, already loaded onto
factory brass. The Final Finish kit contains 10 rounds each of
#1 and #2 grit, while the TMS kit contains 20 rounds of #3. The
basic idea is to fire 5 rounds of #1, clean the rifle, 5 more
#1s, clean again, 5 #2s, clean again, 5 more #2s, continuing
down the line and cleaning every 5 rounds, firing 10 rounds of
standard factory ammunition as the final step in the process.
The instructions also indicate that you should fire 5 rounds of
TMS ammunition every few hundred rounds through your rifle to
prolong accurate barrel life and maintain your results.
Anyway, I placed my order this morning, and in a few days will
have the kit in my hands. Next weekend I will take them to the
range and put them to the test. I will attempt to take some
pictures and get a full review out by next week, including the
step by step and observations made along the way. Just wanted to
get all of this stuff down today so that I am forced to write
the review and not put it off. Hopefully a few adjustments and
we'll have a sub MOA rifle capable of putting one in the eyeball
from a few hundred out.
More to come.

UPDATE: I placed an order for the two maintenance systems (Final
Finish and TMS) on September 23rd. Yesterday, after two weeks of
waiting for my package to arrive, I decided to give Superior
Shooting Systems (the company which produces and sells David
Tubbs products) a call and see what was going on with my order.
The fella I spoke with explained that while they had an order of
Final Finish ready to ship out to me, he "wasn't sure" if they
had any TMS loaded ammo in .270 available to ship but he'd "go
upstairs and look". Because of this, they hadn't put a single
package in the mail. He went on to explain that they were way
behind because a "large distributor" of theirs kept buying up
everything they had. He then told me that if they didn't have
any TMS projectiles made that it would be about 2 months before
they got around to filling my order. I'm gonna be honest, I'm a
little more than infuriated at this point. Still waiting to hear
back from them. I understand the being busy part, and the way
that these products are selling tells me that I may be on to
something good here, but what I can't wrap my mind around is why
there was no communication to me at any point during the
ordering that my products mght be delayed. Either way, we shall
see how they resolve this issue, and there is still plenty of
time for them to do right by me. I will keep an open mind, but
strongly recommend that if anyone else decides to order this
product that they order from Midway USA or another distributor
who can actually fill the order.
More to come.

We always called this seasoning a barrel. kinda like a black pot
you know. we always shoot, clean, oil, for at least the first
box of bullets. Usually before we even put a scope on it. But, I
wanted to tell you that my uncle owns a
http://www.ruger.com/products/no1Varminter/models.html
and it is a fine rifle, if I am not mistaken he has the 6.5 and
it seems to do the trick every time. The 6.5 is a .264 caliber
140 grain bullet with little recoil. He uses this because he is
a handicapped hunter (degenerative disk disease has hampered his
hunting lifestyle) and he can shoot this without crippling
himself. They also make this rifle in more traditional shooting
calibers I would like to get this gun in a .308 It is a very
good looking and very accurate gun.

Yeah, those No. 1 s are niiiice guns. With a good piece of
glass, there'd be no reason to ever miss. The only trade of is
that they are pricey. I looked at them when I first started
researching single shot rifles, and most were 1400 or more. But
I agree, beautiful guns, and from everything I've ever been told
extremely accurate.

He got his for 800 I think. I also think MSRP is 1400, and I'm
not paying MSRP for anything I purchase. Oh i gotta run got a
little yearling action going on.

Nice. I may look into them more once there's a little more cash
flowing around. Good luck with the hunt.

Well it only took me 2 years, but here's my review of the David
Tubbs system. The ammunition I recieved came with excellent
instructions. I followed them to the letter, cleaning between
five shot volleys and allowing the barrel to cool. The barrel
did become noticably easier to clean throughout the process, and
remains easy to clean 2 years later. Accuracy did improve, from
an average group of 1.95" to just under 1.5". Significant enough
to call it an improvement? Eh. Statistically speaking, not
really. But just because it didn't improve this particular rifle
doesn't mean it doesn't work for any rifle, and that is the
important thing to remember. Especially with the number of low
end budget rifles that are coming out these days, a good barrel
lapping process may be helpful to many.
