Help removing moly from my dasher barrel

[BigDaddie]

Hi All,

I would like to get all of the moly out of my barrel....Ive decided to return to naked bullets now. I did a search on moly cleaning and from what I could glean, ammonia is a good solvent to use.

On the ammonia level, I have butch's bore shine, and sweets 7.62. I was thinking about hitting it with the butches and a bronze brush then patches. Then giving it a good working over with JB bore paste.

Does this seem like a reasonable method? If not, any suggestions would be appreciated.

Cheers,

BD

BigDaddie: I went thru the same problem about 5 yrs. ago when I gave up on moly: a lot of claims, with little or no benefits. The moly is burned/baked into the surface of the bore from the heat of the burning powder, some say over 2000 degrees F.), and while I got most of it out, 1 Hart & 2 Shilen barrels) with JB bore paste, a very small amount remained in the corners where the land meets the grooves, as seen w/ a borescope. Just used "naked" bullets after that with all being normal: excellent groups and easy to clean. Check out Hart barrels web site, and read what they think of moly. If someone is happy with moly results, great!. Myself and many others I know were not impressed after giving them a try. Sorta like cleaning, barrel break-in, powder choices, etc. : whatever works for you.

thanks mate,

did u use anything else other than JB? The barrel has only had 126 rnds thru it,28 of those were naked projectiles the rest moly) and I did not coat the bore with the stuff boefore and after shooting as some people do so I'm hoping that I'll get it out a little easier.

I also have about 200 107smk's that I coated. I read somewhere on this forum that a household ammonia bath and a little rub might get all of that off.....that would be nice. I'd hate to have wasted all those bullets!

Try some IOSSO bore paste on a patch wrapped around a nylon bore brush. With no more round count than you've got in that barrel, I seriously doubt whether the amount of moly that could possibly be in your bore would ever cause any sort of problem.

Just give your barrel a normal cleaning and start shooting bare bullets.

You can tumble your bullets to remove the moly.

Now, if your bullets were properly plated, not coated, dunked, sprayed, or wiped on, moly does not build up, get baked on, or burnt into the barrel, nor can you see it in the barrel with a borescope. Quit spreading that.

Bigdaddie I read somewhere that GOJO handcleaner did a good job removing Moly from barrels. The article did state to use the kind that did not have pumice in it. Also heard that Dawn dish soap would also work.

I have not tried this, so don't hold me to it if it doesn't work.

I agree with alf clean the barrel well, and go naked. HAHAHA!

Simple and effective JB/Kroil.... It works

Ditto CJ6.

I believe that what a lot of shooters think is moly in the bore is actually carbon. I've seen it in barrels that have never had a moly'd bullet fired through them, as well as in barrels fired with nothing but moly'd bullets. Whatever - the fastest, most reliable way I've yet found to get carbon out of the throat is IOSSO on a patch wrapped around a nylon bore brush.

I'm always skeptical when someone claims that his custom barrel has never seen a bronze bore brush, yet remains easy to clean with nothing more than Kroil. I read all the moly hype/BS in PS magazine back in the mid-90s, and tried getting by without brushing a very nice Krieger service rifle barrel in 223 - the result was lousy accuracy at 500 & 600yds. When I borrowed a friend's Hawkeye and scoped the bore, the amount of carbon build-up in the throat and on out 8"-9" into the bore was extremely obvious, and it took 3 days of soaking/brushing to get rid of it - that was before I'd tried IOSSO, which might've made the cleaning a bit easier. At any rate, accuracy returned after I'd finished cleaning the crud out, and I've never considered brushless cleaning since. Wonder how many of the guys who've sworn off using a brush and written about doing so have actually inspected their bores with a Hawkeye?

BigDaddie: Guess what I was trying to say, but others said it better is: if you don't get all the moly out, in my experience it does not matter, the barrel will still produce excellent results when returning to "naked" bullets. Flatlander: Yes, I too read all the B.S. articles in P.S., that's what convinced me to try moly. Then read the article,in P.S.) by Kevin Thomas from Sierra bullets, where he explained all the related problems with moly. Thought this was "strange" since it was also about the same time Sierra began to offer moly coated bullets for sale. Then read the articles by "Speedy Gonzales", and saw the borescope/camera video of what a moly barrel looks like. Also believe, after using my "Hawkeye" borescope/ best investment I ever made), a brush, and a tight-fitting one at that) must be used to get the barrel clean. I'm sure IOSSO is every bit as good as JB: I just happened to have JB on hand, but would have used IOSSO if I had it at the time. Both excellent products. Never regretted returning to uncoated bullets.

 

[BigDaddie]

Thanks guys. This is my first experience with the stuff so I guess you go on other people's experiences hence why I posed the question here....although it seems a contentious one

I break back down to a bare bore a few times a year and then recoat with my Tungston coating.

I use a Montana extreme bore brush at .270 for my 6.5 bore. I push it through a few times and then dry patch.

I then use brake cleaner and run soaked patches down the bore and then dry patch.

I then brush it some more and run two wet patches of kroil down the tube and allow to sit overnight.

I then brush it out an use normal bore cleaner the next day.

I then use my tungston grease and recoat the bore.

Never had a problem with accucracy.

RHINOUT!

Al,
I disagree with your above statement. If you examine a bore with a Hawkeye that has shot moly, you will see little islands of moly dispersed throughtout the bore. I had a sacrificial barrel that I experimented with shooting nothing but moly. I cleaned it regularly using Kroil and JB, as recommended. I also use Bore Tech's Moly remover and never totally removed the moly.

chino,
Here's why I say what I say.
I do have a borescope. I defy anyone to look in my barrels and show me any moly. No streaks, no islands, no nothing. You can compare them side by side with a brand new blank and not tell the difference.
I've got a barrel that was shot as a PPC for 2000 rds then rechambered for a prairie dog barrel with another 6000+ rds. thru it. According to what's being said, it should look like a sewer pipe inside. Zip, zero, nothing, nada.
I shoot Hunter Class all day, 100 yd. in the morning, 200 in the afternoon and don't clean at all. Push a patch thru when I get home and take a look inside. Nothing.
I also shoot 600/1000 yd. I've shot my 6.5-284 as many as 70+ rds. without cleaning.,no time) There is absolutely nothing, but a few copper streaks, in that barrel at the end of the day when I look at it.
Now, that's why I said "properly plated" bullets. The original process was impact plated, not sprayed, not coated, not with ceramic beads, and not tumbled by themselves alone w/o anything.
With human nature the way it is, everyone tries to cut corners.
They won't spend the $140 for Neco's kit, instead using some substandard moly dust or spray, applied by various means, then jump on their soapbox telling the world that moly sucks.
I bought a used 223 once, that the guy had used something in it I could never get out. I tried everything but the kitchen sink.
When done cleaning, you could put a clean patch on the jag, work it back and forth, and it would still come out black.
I use to use kroil and JB, but now just use Boretech Eliminator.
A wet patch or two, a little brushing with a nylon brush, let it set a bit, and patch it out. Maybe a little JB for the throat.
Moly, you either love it or hate it. The benefit for me is to be able to shoot more, with less cleaning, with no loss of accuracy. Nothing more, nothing less.

with a good bronze bristle brush, fill the brush full of JB.

25 strokes with a stroke = one forward and one backward should do the job. Refill the brush every 7 strokes.

Good luck

 

[Macs]

Al I also agree I get as many as 180 to 200 rounds between cleanings on my 6x47 and yes checked with a Hawkeye borescope tada, clean in just a few strokes. I also use the same cleaning method other than I use ATF instead of kroil, I do't think it makes alot of differance. They must be plated not coated as stated.

 

[chino1969]

If you like moly and it works for you, then use it. I personally will never put it in a custom hand lapped barrel. That barrel did not have moly impregnated in the bore from the barrel maker and I would think if the claims were true about the benefits of moly, barrel makers would heartily recommend it.

Just for the record, my experience was shooting factory moly coated bullets,Sierra, Hornady, Berger) and not plating myself.

Hart's website doesn't recommend moly and Kreiger's is non-commital.

I would be connecting a hose from your hot water service to your bore guide and run boiling water down your barrel leave for 5-10 minutes.
Then patch water out and apply sweets 7.62 with a nylon brush be well ventilated as the fumes can be excessive this wont harm your barrel and will remove the moly.

and go naked. HAHAHA!

I did and got arrested! (yes I know it is an old post but couldn't help myself)
