Leaving Sweets in your bore more than 10 minutes may cause pitting. And you
must completely dry the bore by using clean swabs after using Sweets.

As it says on the Sweets bottle, you need to run a patch with some oil on
it through the bore after finishing with Sweets. This neutralizes the
Sweets and prevents the damage you had.
But I'm with you, I don't like using anything that caustic on my rifle bores.

Pete, sorry to hear of your bad experience, but to blame Sweets may be too
easy. I use Sweets on all of my rifles and some of my magnum revolvers, and
have been doing so for quite some time; enough time that I'm even used to the
smell! I have absolutely zero pitting in my bores. What I do have are bores
free of jacket fouling. Perhaps there is another explaination for your
predicament. I'm not a chemist, but I don't believe there's anything in Sweets
which could eat steel. I hope you find your answer.

You should have sent it to me.
I've used Sweets without problem for several years in my M1 (GI barrel)
and do not see any indication of pitting.
My method has been to clean the powder fouling with Hoppe's #9, patches,
and brass brush - when the powder/carbon fouling has been removed I
use the Sweets to remove copper fouling - run a wet patch thru the
barrel and let it set about 10 minutes, then run a dry patch thru the
barrel. I usually do a few repetitions of Sweets and then the patches
show only faint traces of blue from the copper being removed.
After the Sweets I ALWAYS use a patch wet with Hoppe's #9, and then
dry patches.
I would not leave a barrel wet with Sweets (or other strong cleaners
that contain ammonia) for more than 10-20 minutes.
Plain Hoppe's #9 will also removed copper fouling, but it takes much
longer than with Sweets.

Anybody else had problems? One bad batch of Bisleys got through a few years
ago, rusting out a few barrels out here. All I'm saying is IF Sweets has
caused problems it is VERY unusual.

Maybe your barrel was already pitted and the ammonia removed the copper,
which was hiding the pitting. Hey, it could happen......

After a few wet patches, did you clean it out with something else
to nutralize it? I hope you did'nt leave it in there for more than 10
minutes.

Did you use any other solvent in the same barrel? I've been told that
Sweet's combined with some solvents like Shooter's Choice can form a
combination that is corrosive.

Ask not what your country can make other people do for you.
My procedure is:
1. I mount a nylon (or plastic) bore brush. Do not use a bronze brush! The
ammonia will go after the brush.
2. I wrap a patch around the brush. The purpose of the brush is to hold the
patch only.
3. I dip the brush/patch combination into a bottle of the cheapest ammonia
containing household cleaner. I think it cost me $1.35 for a half gallon.
4. Stroke it back and forth through the bore a few times. Replace patch.
5. Repeat 3 and 4 until all copper is gone. BTW, all the powder residue will
be gone also.
6. Rise brush under faucet.
7. Patch brush and wet with water only. Run through bore.
8. Repeat 6 and 7. This is to remove all soap residue left from the cleaner.
9. Swab bore with "Ed's Red".
10. Repeat 9.
Store the rifle. The bore is spotless, there is not a trace of water and it
is coated with oil. And. . .it is cheap!

Another factor is that Sweets will sometimes react with some of the
components of other solvents like Shooter's Choice to form a pitting
chemical - this has been documented in Precision Shooting, etc.
Apparently the problem occurs when some Sweets is left in the bore, and
SC is applied and left in the bore to soak. If the Sweets is completely
removed first, and the bore is not stored with SC, the pitting and light
frosting reported does not occur. Many current bore cleaners recommend
NOT to use amonia-based cleaners in conjunction with them.

PPS. The attached letter may also be enlightening.

Rick ... right! Not just match grade, but I believe match grade
stainless in particular. As I recall, the ammonia attacks one of the
components of the stainless alloy, leading to cracking of the bore
surface; this is speeded by heat and pressure, and will cause the rifle
to throat out much quicker than it otherwise would. Further, it is not
something that stops when you quit using Sweets. The ammonia bonds with
the metal in deep (on a microscopic scale) cracks. Further, as I
recall, the ammonia in Sweets reacts with other solvents like Shooter's
Choice and Hoppes and their product is quite corrosive and stubborn as
hell ... nigh impossible to remove. I believe some shooters have
resorted to using weak acid solutions to try to remove the ammonia salts
.
All in all, nasty stuff. Much better to avoid Sweets with stainless
barrels.
As I recall, it was developed for cleaning heavy copper out of M1A match
rifles. Every one of those I ever saw had a blued steel barrel, which
is not as succeptible to the corrosion caused by Sweets. Further, being
shot with iron sights, they simply do not require the same level of
accuracy that a benchrest rifle, or possibly even a varmint rifle,
requires ... though saying that will most certainly piss off a few
highpower competitors.
The big problem, then, is using a product for a job it was not intended
to do.
The answer to heavy fouling, in stainless rifles, in my experience, is
not harsh copper solvents, but instead, mildly abrasive compounds
designed for physical removal. Benchrest shooters have been using JB,
USP, and Rem Clean for years with no problems. These mild abrasives
have a very fine grit, so fine that they do not effect dimensional
changes, but if anything, polish the bore yet smoother. It is important
with 'em to use a bore guide, 'cause they COULD bell the muzzle and
affect the throat similarly if a cleaning rod with 'em on it were pushed
hard against those areas.
Personally, I use USP in my stainless rifles that foul badly, then used
patches with Shooters Choice to "hose" it out, and follow with a little
Kroil oil.

I haven't read the reports but Sweets is used very heavily here in
Australia both in benchrest and for hunting rifles.

Sweets 7.62 was developed in Australia for use in Full Bore competition.
This is competition using military issue ammunition (7.62 x 51) in up to
1000 yd competition withg iron sights. Rifles are typically heavy barreled
bolt actioned single shots. Many a stainless as are many of the benchrest
guns that use Sweets here without any apparent problem.
Most shooters use Sweets to get out the copper and something else top get
out powder fowling.

Anything abrasive enough to polish the bore must by definition also be
rounding off lands etc. If you picture an bore as a surface with various
projections and hollows which tear of minute paricles of copper and hold
them in the hollows, in order to get the copper out, you must cut back the
metal to remove the low spot (this is the polishing you refer to). If you
don't remove that copper which lays in the hollows, it will quickly gather
more copper on subsequent shots because similar metals tend to gall quite
severely. So I would suggest that a solvent which actually removed *all*
the copper is a better method. Those cleaning methods that use
electrolosis might be even better (RCBS etc).
I'm not qualified to comment on whether Sweets attacks or bonds to any
particular alloy of Stainless steel... Just thought I'd share the Aussie
experience :)
BTW, my wife would agree with you just so I didn't stink the house up with
the stuff anymore ;-)
