Sweets 7.62 and foaming bore cleaner?



Quote:
I am no expert by any means, but I wouldn't mix chemicals in my barrel. Others may disagree and that's okay too.





I will agree with 4949 on this, with the exception of using an oil thereafter as a last step.....If your using Sweets 7.62 theres no need to add another coppersolvent to the mix....There are two specific cleaners that should not be mixed but they escape me at the moment....

Even on the worst of the worst, I'll only brush once maybe twice and the rest patches...with a nylon brush it can trick you, and leave copper that it picked up before...making your patch blue.....

so with that said just run wet patches of Sweets through until they are clean then dry patches and finally a good detergent oil to protect the bore...

I shoot alot of very hot fast calibers and deal with copper regularly...If I were to shoot 250 rnds through my Swift (50gr bullet @ 4050) then I would be expecting the worst in terms of getting that copper out... but I can shoot 250rnds from my AR without any cleaning at all and it may take some elbow grease to get back to bare metal but its not that bad...... Now I have a savage that used to be almost impossibe to de-copper...

you'll get it out, also I will second the vote for JB bore on the tough to clean barrels... /ubbthreads/images/graemlins/grinning-smiley-003.gif

Good luck and I love the tractor....how do you hide that on stand... /ubbthreads/images/graemlins/confused1.gif /ubbthreads/images/graemlins/grin.gif
 
I'm not really mixing, one is swabbed out with many dry patches before the second is applied, but I will try it with the sweets only on your recommendation. I just pretend I'm farming then shoot em when they come out to chase the mice. They never see it coming!

I'll probally take a beating for this but it's the way a good gunsmith taught me. 1. insert bore guide 2. pour 20-25 drops of sweets thru bore guide into barrel 3. wait 15 minutes 4. run patches thru till dry,if patches are still blue go back and repeat from step#2.Oil bore after sweets and run dry patchs thru to dry the oil. Now he's switched to foaming cleaners with accelerants,says its faster & works just as good.
 
I use sweets, but I also use Simply Remarkable. I soak a swab and run it in the bore till I get foam out the other end, then I let it set for about 10 minutes. Run a few dry patchs through it and usually I done. Sometimes I might have to do it a couple of times. I also picked up a bottle of Barnes CR-10. It seems to work pretty good, but smells pretty high in amonia content.
 
MPFD, I cleaned that copper fouling pig after 60 shots for 600 rounds, then the barrel started shooting better. I was able to extend my cleaning session to 100 shots on red hot p. dog towns.

I think that very few people have had the experience of having a rifle that fouls like you are describing.

Hope this helps!
 
I've seen a few barrels like that, and most went back to the factory for replacement. The others were re-barreled with Shilen or other quality barrels, and no more problems. Sadly, some of the factory replaced barrels weren't much better than what had been replaced...Savage in particular. For cleaning, I use Wipe Out, and if its ugly, JB's can help, but Wipe Out, overnight, usually cleans stuff that hasn't been neglected too badly. I never could tell that the Accelerator did anything; smells like it should have some vodka added, for a drink. Guess thats just me.
 
Tonight after about another 2 hours of cleaning I finally stopped seeing color. I came home from work and used sweets only for about another ten passes (10-15 min between) and started not seeing anymore blue. I ran several dry patches through and a little rem oil and put that hog to bed. I have to say I was pretty discouraged last night when I went to bed, but it did take alot less elbow grease to get it clean this time. Now is there anyway I can hurt this barrel with JB's and what are the best tools to use? Do they make a bore guide for AR upper recievers?

Allen,,,,,,, you're probably thinking of Sweets and Shooters Choice.
That's a no no.

Sinclair makes bore guides for AR's.
JB's has directions on the label. It's a last resort IMO.
 
That link that Ackleyman gave you to Sinclair International will have everything you need. I love Sinclaires...but my checkbook doesn't.

MPFD,

I can't answer your other questions, but I will say that I generally clean the copper out of the barrels on my bolt guns after every 20 rounds. Rarely do I shoot more than 20 through a bolt gun at one outing, but if I do then I will clean the copper out when I am done.

For my AR's (with non chrome lined barrels) I clean them with sweets after every shooting session. This way, the copper doesn't have a chance to build up as much.

I am glad you were able to clean out your barrel.

Good shooting.

Your answer is easy. Use JB Bore cleaner on a good bronze bristle brush, follow with Sweets, let the sweets sit up in the bore for no more than 15 minutes.

Brushing with JB will do a little polishing. Use good bronze bristle brushes available from www.sinclairintl.com
are the quality you want to use.

Your barrel probably was over looked for lapping, hence the roughness.

Shooting bullets with a lot of bearing surface will promote copper buildup faster, Bullets such as the 60g and heavier are what I am talking about. A bullet such as a 55g Sierra BT for yotes or a 55g Sierra Blitz king for p. dogs would have much less bearing surface than the 69's and heavier.

You should consider cleaning your rifle frequently to aid in copper removal.

The problem with Wipe out is that it is a time activated chemical reaction that takes over night soakings to work properly.

I had a cheap custom barrel installed on a 22PPC just to see how a bottom of the barrel in quality would shoot if chambered with a custom match reamer. It would shoot in the .600's from the get go, and the barrel would turn solid copper after 60 rounds. After about 600 rounds, the rifle started grouping in the .300's. I cleaned the bore on this copper fouling pig with the JB and a brush as I mentioned.

Good luck!



A BIG DITTO! /ubbthreads/images/graemlins/grinning-smiley-003.gif
JB is an important part of the solution.
And I never leave Sweet's in a bore longer than 20 minutes. 15 minutes is a good recommendation too. Longer will allow the Sweets to etch the bore, which is bad...

i use jb bore bright its done wonders with the fouling invest in some a lil REALLY does go a long way and scrubb the heck out of it with it and it will get out the fouling trust me i had to do it for my buddies AR it came out sparkling and the copper would lay on that polished bore and make it alot easier to scrub out. premenative maintence goes along way
 
FWIW, Pac Nor reccomends "neutralizing" the barrel in between solvents/cleaners using 90% rubbing alcohol. I've always done this and still can get some blue streaks from brass jags.

I have a J&T bbl that fouled badly from the get go. Shot great, but loaded up w/ copper. Polished/lapped it w/ Flitz (I believe this is about 600grit) and the fouling subsided. As stated above, get a coated rod and a JP Enterprises bore guide.

I found this cleaner made by gunslick called Copper-Klenz that is the best I have ever used ....eveh!Try it what have you got to loose other than copper /ubbthreads/images/graemlins/smile.gif
 
Spray it down with simple green let it soak for a while then go to town on it just make sure you get it really dry because the simple green is water based.
 
I will tell you in my experience I dont see what all the fuss is about sweets /ubbthreads/images/graemlins/confused1.gif. I had a friend bring me a gun that was dirty like you wouldnt belive /ubbthreads/images/graemlins/shocked.gif. I used sweets and after two nights of cleaning for hours I gave up /ubbthreads/images/graemlins/mad.gif. I called a gunsmith who lives close to me and he told me to use Barnes Cr-10. I picked some up a few daya later and wow. It took a total of ten minutes and the barrel was spotless /ubbthreads/images/graemlins/bowingsmilie.gif /ubbthreads/images/graemlins/bowingsmilie.gif. I wont waste my money again on sweets. By the way I always use coated or tipton carbon fiber rods and nylon brushes /ubbthreads/images/graemlins/grinning-smiley-003.gif.
